!!! UNDER CONSTRUCTION !!!

AT commands are used as an interface with Nemeus Communication modules. Modules can be driven at 3 different levels:

Radio level: embedded AT server uses RF SX127x driver API (LoRa™and FSK modulations can be used).
LoRa™WAN level: embedded AT server uses LoRa™WAN library API (available only when the library is present in embedded software).
SIGFOX™ level: embedded AT server uses SIGFOX™ library API (available only when the library is present in embedded software).

When radio level is used, no device personalization is required, it is up to AT client application to implement network layer according to the network the device is attached (the module doesn’t know the network).

When LoRa™WAN level is used, the device is personalized with the following parameters:

Whatever the activation type, a 64 bits device unique identifier.
When Activation By Personalization (ABP) is used:
- An AES128 network session key for MIC computation and encryption of MAC control commands on port 0.
- An AES128 application session key for encryption of application payloads (not required when data encryption is disabled on the module).
- A device address
When Over The Air Activation (OTAA) is used:
- A 64 bits join server unique identifier.
- An AES128 Key used to derive the network and application session keys.

The modules are personalized with Nemeus OUI during production phase and they can’t be modified. The device unique identifier is read-only and the AES128 keys are hidden.

The application unique identifier is modifiable by AT command.

When SIGFOX™ level is used, the device is personalized with the following parameters:

The read-only device unique identifier.
The hidden AES128 security key.
The initial read-only Portability Access Code (PAC).

Before driving the module, the AT client application must activate the level it wants to use.

LoRa™WAN and SIGFOX™ levels can be activated in parallel, it is called the dual mode.

Radio level can't be activated in parallel with LoRa™WAN and/or SIGFOX™ levels.

For evaluation/test purpose, Nemeus recommends to use NemeusATK java application to drive the module.

1 UART configuration

The UART configuration for Modem connection is as follows:

Baud Rate : 38400
Data : 8 bits
Parity : None
Stop : 1 bit
Flow control : None
End line character : <LF>

E.g. Typical configuration given by ‘stty’ command on linux:

speed 38400 baud; rows 0; columns 0; line = 0;

intr = ^C; quit = ^\; erase = ^?; kill = ^U; eof = ^D; eol = <undef>; eol2 = <undef>;swtch = <undef>; start = ^Q; stop = ^S; susp = ^Z; rprnt = ^R; werase = ^W; lnext = ^V;flush = ^O; min = 1; time = 0;

2 AT commands

At command are split according to communication layers. This is a list of main AT commands for SW given in ‘compatibility’ paragraph. The full list and limitation can be found in SW delivery note.

Formalism is the following:

For each group among RF, RFRX, RFTX, MAC and SFX, the command AT+<group>= HELP describes available sub-commands. Example:

AT+MAC= HELP
+MAC: <cmd>,<param_1>,…,<param_N>
+MAC: <cmd> are ON,OFF,?,SET,SCH,RCH,STI,RTI,SRX,RRX,SNDTXT,SNDBIN,RCVTXT,RCVBIN,STOPRCV,SNDLCR,DEVUID,DEVADDR,APPUID,APPKEY,NSKEY,APPSKEY
+MAC: <cmd>? Lists parameters of <cmd> if any
OK

When a sub-command has parameter, AT+<group>= <cmd>? Describes the parameter list. Example:

AT+MAC=SNDTXT?
+MAC: SNDTXT,<textpayload>,<nbrepeat>,<port>,<mode>
OK

When command is unknown “command not found (‘try help’)” is returned.

AT commands are not cancelable, thus AT client application must wait for AT response before sending a new command.

Due to UART Rx buffer size, an AT command can't exceeds 511 characters.

Intentionally left blank

6 AT RF commands

RF commands are dealing with the RF Layer. This layer should be started before using most of RF commands listed in this section (unless stated otherwise).

3 groups of commands exist:

+RF group: commands common to TX and RX functions.
+RFTX group: commands dedicated to TX functions.
+RFRX group: commands dedicated to RX functions.

6.1 AT+RF=HELP

This command is used to know the list of sub-commands.

6.1.1 Response

OK.

6.1.2 Example

AT+RF=HELP
+RF: <cmd>
+RF: <cmd> are ON,OFF,?,RPER,SPER,RSW,SSW

OK

6.2 AT+RF=ON

This command is used to start RF layer (Radio driver) and is mandatory in order to use most of RF commands listed in this section (unless otherwise stated).

6.2.1 Response

ERROR is returned if either LoRa™WAN stack or SIGFOX™ stack is using the radio (Tx or Rx is ongoing).

Else OK is returned.

If LoRa™WAN stack was ON (but not using the radio), it is automatically set to OFF.

If SIGFOX™ stack was ON (but not using the radio), it is automatically set to OFF.

6.3 AT+RF=OFF

This command is used to stop RF layer (Radio driver). After calling this command, most of RF commands listed in this section will return ERROR (unless stated otherwise).

RF layer stop (Radio driver).

6.3.1 Response

Always OK.

6.4 AT+RF=?

This command is used to read the current RF layer state.

6.4.1 Response

Always OK.

6.4.2 Example

AT+RF=?
+RF: OFF
OK

6.5 AT+RF=RPER

This command is used to read the Packet Error Rate state, the power offset, the RSSI offset for LoRa™/LoRa™WAN carrier sensing, the RSSI offset for FSK/SIGFOX™ carrier sensing and the frequency offset for SIGFOX™ Tx.

6.5.1 Response

Always OK.

+RF: <per_state>,<pwroffset>,<loracsoffset>,<fskcsoffset>,<freqoffset>

6.5.2 Example

AT+RF=RPER

OK

6.6 AT+RF=SPER

This command is used to set the Packet Error Rate state, the power offset, the RSSI offset for LoRa™/LoRa™WAN carrier sensing, the RSSI offset for FSK/SIGFOX™ carrier sensing and the frequency offset for SIGFOX™ Tx.

The following formalism is used. It can be checked by the AT+RF=SPER?command:

+RF=SPER,<per_state>,<pwroffset>,<loracsoffset>,<fskcsoffset>,<freqoffset>

<per_state> PER state, unchanged when absent (string true or false).

<pwroffset> is the Power offset (signed decimal in dBm)

<loracsoffset> is the RSSI offset in LoRa™ (signed decimal in dB)

<fskcsoffset> is the RSSI offset in Fsk and SIGFOX™ (signed decimal in dB)

<freqoffset> is the frequency offset in SIGFOX™ (signed decimal in Hz)

When PER state is true, a counter is added at the beginning of Tx frames. This counter is used on Rx side to compute the Packet Error Rate.

6.6.1 Response

OK if <per_state> is “true”, “false” or omitted.

ERROR if <per_state> is syntactically incorrect.

6.6.2 Example

AT+RF=SPER,true
OK

6.7 AT+RF=RSW

This command is used to read the current LoRa™ and FSK synchro words. Synchro words are in hexadecimal format (see formalism on SSW command)

<LoRa_SyncWord> LoRa™ Synchro Word (one byte encoded as hexas digits)

<Fsk_SyncWord> FSK Synchro Word (up to six bytes encoded as hexa digits)

A synchro word is unchanged when related parameter is absent.

6.8.1 Response

OK if parameters are correct or omitted.

ERROR if FSK synchro word is too long (6 bytes/12 hexa digits max) or number of digits is not even.

6.8.2 Example

AT+RF=SSW, 12,69817E96
OK

6.9 AT+RFTX=HELP

This command is used to know the list of sub-commands.

6.9.1 Response

+RFTX :  LORA,868100000,14,125000,7,1,true,8,0,false,false,0,0,0,5,false,true,false
OK

6.11 AT+RFTX=SET

Write Tx parameters. This command does not need the RF layer to be ON. Only modified parameters can be specified.

The following formalism is used. It can be checked by the AT+RFTX=SET? command:

+RFTX= SET,<mod>,<freq>,<pwr>,<bw>,<dr>,<cr>,<txcrcon>,<preamble>,<fdev>,<fixed_len>,<txiqinv>,<rxw1>,<rxw2>,<tstamp>,<symbtimeout>,<rxiqinv>,<rxcrcon>

The parameters <symbtimeout>, <rxiqinv> and <rxcrcon> are used only when an Rx window is specified.

<tstamp> is the absolute clock time of the module. If the time is over, the frame is immediately transmitted. Usually this timestamp is a delay added to an Rx timestamp (feature not fully implemented)

When <fixed_len> is true then the fixed length value is the size of the sent payload and the Rx side must know this size.

6.11.1 Response

Always OK.

6.11.2 Example

To set the <pwr> to 12 and the <txcrcon> to false:

AT+RFTX=SET,,,12,,,,false
OK

6.12 AT+RFTX=SEND, (for test purpose)

Transmit <nb_frames> numbered frames every <interval> ms.

AT+RFTX= SEND,<nb_frames>,<interval>

Default values : <nb_frames> = 1, <interval> = 500 (ms).

If <per_state> is true (see AT+RF=SPER command), transmitted frames contain a counter on 4 bytes followed by a 32 bytes fixed pattern.

This command is used as a generator for Packet Error Rate (PER) computing.

6.12.1 Response

6.15 AT+RFTX=SNDTXT,

Repeat <nbrepeat> text frames every 500 ms.

AT+RFTX= SNDTXT,<txt>,<nbrepeat>

Default values : <nbrepeat> = 1.

<txt> parameter is transmitted as received on serial link, the module doesn’t manage any character set.

If <per_state> is true (see AT+RF=SPER command), a 4 bytes counter is added at the beginning of the frame.

6.15.1 Response

OK if <nbrepeat> have been successfully sent.

ERROR if RF layer is OFF or if one frame has not been successfully sent.

6.15.2 Example

AT+RFTX=SNDTXT,HELLO WORLD,3

6.16 AT+RFTX=SNDBIN,

Repeat <nbrepeat> binary frames every 500 ms.

AT+RFTX= SNDBIN,<bin>,<nbrepeat>

Default values : <nbrepeat > = 1

<bin> parameter is hexadecimal coded in ASCII (2 ASCII characters for 1 binary byte).

If <per_state> is true (see AT+RF=SPER command), a 4 bytes counter is added at the beginning of the frame.

6.16.1 Response

OK if <nbrepeat> have been successfully sent.

ERROR if RF layer is OFF or if one frame has not been successfully sent.

6.16.2 Example

To send 2 times the 3 bytes 1A 2B 3C:

AT+RFTX=SNDBIN,1A2B3C,2
OK

6.17 AT+RFRX=HELP

This commandis used to know the list of sub-commands.

+RFRX: <mod>,<freq>,<bw>,<dr>,<cr>,<rxcrcon>,<fixed_len>,<rxiqinv>,<timeout>,<symbtimeout>,<lnaboost>

<timeout> and <symbtimeout> parameters are no more used by radio stack (they are still present for compatibility with previous module versions).

6.18.2 Example

AT+RFRX=?
,true
OK

6.19 AT+RFRX=SET,

Set Rx parameters. Only modified parameter can be specified.

The following formalism is used. It can be check by the AT+RFRX=SET?

command:<mod>,<freq>,<bw>,<dr>,<cr>,<rxcrcon>,<fixed_len>,<rxiqinv>,<timeout>,<symbtimeout>,<lnaboost>

<timeout> and <symbtimeout> parameters are no more used by radio stack (they are still present for compatibility with previous module versions).

6.19.1 Response

6.19.2 Example

To set <dr> parameter to 7:

AT+RFRX=SET,,,,7
OK

6.20 AT+RFRX=RECV (for test purpose)

Single frame reception with PER computation if <per_state> is true (see +RF=SPER command).

RF layer comes back to IDLE state after reception or after AT+RFRX=STOP command.

6.20.1 Response

OK if RF layer is ON and not already receiving.

ERROR if RF layer is OFF or is already receiving.

+RFRX: <per>,<rssi>,<snr>,<crcerr>,<tstamp>,<binary payload>

Then, when a frame is received the unsolicited response below is sent:

If <per_state> is true (see +RF=SPER command):

+RFRX: 100%,-35.00,7.00,0,1521551302,12000000CAFEDECA…

Where 100% is the PER, -35.00 is the RSSI level, 7.00 is the SNR, 0 is “no CRC error”, 1521551302 is the Rx clock time in ms and 12000000CAFEDECA is the received payload, starting with the 4 bytes counter.

If <per_state> is false:

+RFRX: ,-35.00,7.00,0,1521551302,CAFEDECA…

PER is not displayed and the 4 bytes counter is not present in the payload (it means that Tx device also has <per_state> set to false.

After frame reception the Rx is automatically stopped.

6.20.2 Example

AT+RFRX=RECV
OK
+RFRX: 100%,-35.00,7.00,0,1521551302,12000000CAFEDECA

6.21 AT+RFRX=START (for test purpose)

RF layer stays in RX until Rx stop command is sent (see AT+RFRX=STOP)

6.21.1 Response

OK if RF layer is ON and not already receiving. ERROR if RF layer is OFF or is already receiving.

When a TX has been performed during Reception, An AT+RFRX=STOP command may be needed to avoid ERROR from this command

After frame reception RF layer stays in RX (RX stop command must be used to leave RX mode).

6.21.2 Example

AT+RFRX=START
OK
+RFRX: 100%,-35.00,7.00,0,1521551302,12000000CAFEDECA
+RFRX: 100%,-32.00,7.00,0,1521554506,13000000CAFEDECA
…

6.22 AT+RFRX=STOP

OK

6.23 AT+RFRX=CONTRX

Continuous reception without PER computation.

6.23.1 Response

OK if RF layer is ON and not already receiving.

ERROR if RF layer is OFF or is already receiving.

Then, for each received frame, the unsolicited response below is sent:

7 AT LoRa™WAN (MAC) commands

3 types of AT strings are specified:

MAC commands: AT+MAC=<cmd>,<param1>,…,<paramN>.
MAC solicited responses: +MAC: <param1>,…,<paramN>. These responses are sent in response to MAC commands, just before the OK response, that’s the reason why the <cmd> is not present in the solicited responses. Several solicited responses may be sent between the MAC command and the OK response.
MAC unsolicited responses: +MAC: <cmd>,<param1>,…,<paramN>. These responses are not necessarily sent between the MAC command and the OK response, that’s the reason why the <cmd> is present in the unsolicited responses.

When an AT client application just need to send and receive frames, the following commands are used:

AT+MAC=? to know the current MAC mode (OFF/ON, ABP/OTAA, Class A/C).
AT+MAC=OFF and AT+MAC=ON,… to change the MAC mode.
AT+MAC=DEVADRR and unsolicited +MAC: DEVADDR,… to know the current state of an OTAA device.
AT+MAC=SNDBIN,… to send uplink frame.
+MAC: RCVBIN,… when receiving downlink frames and to know Rx windows termination.
+MAC: END to know when the LoRa™WAN layer is back to idle.

All other commands are not really required, they are mainly used by NemeusATK Java application to manage the LoRa™WAN layer (for IOT purpose, device provisioning …).

7.1 AT+MAC=HELP

This commandis used to know the list of sub-commands.

7.1.1 Response

OK.

+MAC: <cmd>? Lists parameters of <cmd> if any
OK

7.2 AT+MAC=ON

This command is used to start LoRa™WAN layer and is mandatory in order to use most of MAC commands listed in this section (unless otherwise stated).

If Radio stack was ON, it is automatically set to OFF.

AT+MAC=ON,<minor_ver>,<class>,<otaa>

<minor_ver> is deprecated, only the default value (3) is accepted
<class> is A or C.
<otaa> is 0 for ABP and 1 for OTAA.

7.2.1 Response

Stop LoRa™WAN layer.

7.3.1 Response

Always OK.

7.4 AT+MAC=?

Read current LoRa™WAN layer status.

To change LoRa™WAN layer status, AT+MAC=OFF and AT+MAC=ON,… must be performed.

7.4.1 Response

Always OK.

+MAC: <state>,<minor_ver>,<class>,<ch_pages>,<ism_band>,<otaa>,<lwan_fw_ver>,<lwan_prot_ver>,<lwan_rp_ver>

<state> is ON, OFF or DUAL. DUAL means that LoRa™WAN and SIGFOX™ stacks are both ON.

<minor_ver> always V3.

<class> is A or C.

<page> is the number of pages of 16 channels available at LoRa™WAN layer (in terms of memory space), 1 page for EU863-870, AS923 and RU864-870, 5 pages for US902-928..

<ism_band> is 8 for EU863-870MHz, 9 for US902-928MHz, 10 for AS923MHz and 13 for RU864-870MHz. ISM band can’t be modified dynamically, it is set at compilation time.

<otaa> is 0 for ABP and 1 for OTAA.

<lwan_fw_ver> is the firmware version of the LoRa™WAN stack

<lwan_prot_ver> is the version of the LoRa™WAN protocol specification

<lwan_rp_ver> is the version of the regional parameters specification

7.4.2 Example

A class A US902-928MHz device with 80 channels (5*16) in OTAA:

AT+MAC=?
+MAC: ON,V3,A,5,9,1,1.0.0.0,1.0.4.0,1.0.1.0
OK

7.5 AT+MAC=SNDBIN

Binary frame transmission.

AT+MAC= SNDBIN,<binpayload>,<nbrepeat>,<port>,<mode>,<add_tx_rx_info>,<dev_time_req>

If <mode> value is 0 then the frame is sent in unacknowledged mode (default value when mode is omitted).

If <mode> value is > 0, then the frame is sent in acknowledged mode.

<nbrepeat> specifies the number of repetitions in acknowledged mode (0 when omitted). Since LoRaWANV1.0.4 the <nbtrans> parameter is also used in acknowledged mode (see RDR/SDR commands), thus if (<nbrepeat>+1) <= <nbtrans> then the frame will be sent <nbtrans> times, if (<nbrepeat>+1) > <nbtrans> then the frame will be sent 2*<nbtrans> times, ...

If <port> is omitted then port 2 is used by default (port 1 is reserved to embedded generic application).

if <add_tx_rx_info> > 0 then for each transmission performed and each Rx performed the following responses are sent after the +RCVBIN:

+MAC: TXINFO,<tx_index>,<tx_freq>,<toa>

+MAC: RXINFO,<rx_index>,<rx_freq>,<toa>

if <dev_time_req> > 0 then a device time request is added in the MAC header of the uplink frame

7.5.1 Response

OK if MAC is ON and frame has been successfully sent (and acked if acked mode was requested).

ERROR if MAC is OFF or frame has not been successfully sent (or not acked after repetitions if acked mode was requested).

ERROR also if SIGFOX™ stack is using the radio.

ERROR also when port is reserved regarding LoRa™WAN standard.

7.5.2 Unsolicited responses

The unsolicited responses below are sent when AT client application has registered to receive unsolicited events (see AT+MAC=RCH command).

+MAC: SND,<busytime>

<busytime> is in ms.

This unsolicited response can be sent 2 times:

One time with busytime > 0 if no channel was free due to duty cycle restriction
One time with busytime = 0 at Tx time.

+MAC: RCH,<chan>,,,,,<busytime>,<page>

<busytime> is in ms.

Sent for each enabled channel.

+MAC: END

To indicate when LoRa™WAN layer is back to idle.

7.5.3 Example

AT+MAC=SNDBIN,1A2B3C,3,2,0
+MAC: SND,4355
+MAC: SND,0
+MAC: RCH,0,,,,,4480,0
+MAC: RCH,1,,,,,4480,0
+MAC: RCH,2,,,,,4480,0
OK
+MAC: RCVBIN,2,false,,0.00,0.00
+MAC: END
On duty cycle expiry (4480 ms after the Tx), channels become available:
+MAC: RCH,0,,,,,0,0
+MAC: RCH,1,,,,,0,0
+MAC: RCH,2,,,,,0,0

7.6 AT+MAC=RCVBIN

Register for receiving downlink frames on specified port, payload is output as binary hexa string.

AT+MAC= RCVBIN,<port>

This command is no more required because all downlink frames are routed on serial link except when the port is used by an embedded application.

7.6.1 Response

OK if MAC is ON and port is valid and free.

ERROR if MAC is OFF or port is invalid or port is already used by an embedded application.

7.6.2 Unsolicited Response

+MAC: RCVBIN,<port>,<more>,<binarypayload>,<rssi>,<snr>

When <more> is true, it means that more downlink frames are pending in MAC server. If piggyback setting is disabled and device class is A, LoRa™WAN layer will automatically poll the server to receive more downlink frames.

The RCVBIN unsolicited response is always sent after a Tx, even if no frame has been received. It indicates the end of Rx windows.

For a class A device, it is sent when a downlink frame has been received or at the end of the Rx window 2 (if no downlink frame has been received).

For a class C device, it is sent when a downlink frame has been received or at the end of the Rx window 1 (if no downlink frame has been received).

If the Tx was in ack mode, the RCVBIN is sent before the OK (or ERROR NOACK) response of the Tx (SNDBIN or SNDTXT command).

If the Tx was in unack mode, the RCVBIN is sent after the OK response of the Tx (SNDBIN or SNDTXT command).

7.6.3 Example

AT+MAC= RCVBIN,2
OK

Then when a frame is received on port 2 and more downlink frames are pending:

+MAC: RCVBIN,2,true,1A2B3C4D,-43.00,7.00

7.7 AT+MAC=SNDTXT

It is the same command as AT+MAC=SNDBIN except that the payload is interpreted as text and is transmitted as received on serial link (no translation from hexa ASCII to hexa binary is performed).

AT+MAC= SNDTXT,<textpayload>,<nbrepeat>,<port>,<mode>,<add_tx_rx_info>,<dev_time_req>

Text frame transmission.

If <mode> value is 0 then the frame is sent in unacknowledged mode (default value when mode is omitted).

If <mode> value is > 0, then the frame is sent in acknowledged mode.

<nbrepeat> specifies the number of repetitions in acknowledged mode (0 when omitted). Since LoRaWANV1.0.4 the <nbtrans> parameter is also used in acknowledged mode (see RDR/SDR commands), thus if (<nbrepeat>+1) <= <nbtrans> then the frame will be sent <nbtrans> times, if (<nbrepeat>+1) > <nbtrans> then the frame will be sent 2*<nbtrans> times, ...

If <port> is omitted then port 2 is used by default (port 1 is reserved to embedded generic application).

if <add_tx_rx_info> > 0 then for each transmission performed and each Rx performed the following responses are sent after the +RCVBIN:

+MAC: TXINFO,<tx_index>,<tx_freq>,<toa>

+MAC: RXINFO,<rx_index>,<rx_freq>,<toa>

if <dev_time_req> > 0 then a device time request is added in the MAC header of the uplink frame

7.7.1 Response

OK if MAC is ON and frame has been successfully sent (and acked if acked mode was requested).

ERROR if MAC is OFF or frame has not been successfully sent (or not acked after repetitions if acked mode was requested).

ERROR also if SIGFOX™ stack is using the radio.

ERROR also when port is reserved regarding LoRa™WAN standard.

7.7.2 Unsolicited responses

The unsolicited responses below are sent when AT client application has registered to receive unsolicited events (see AT+MAC=RCH command).

+MAC: SND,<busytime>

<busytime> is in ms.

This unsolicited response can be sent 2 times:

One time with busytime > 0 if no channel was free due to duty cycle restriction
One time with busytime = 0 at Tx time.

+MAC: RCH,<chan>,,,,,<busytime>,<page>

<busytime> is in ms.

Sent for each enabled channel.

7.7.3 Example

AT+MAC=SNDBIN,HELLO WORLD,3,2,0
+MAC: SND,4355
+MAC: SND,0
+MAC: RCH,0,,,,,4480,0
+MAC: RCH,1,,,,,4480,0
+MAC: RCH,2,,,,,4480,0
OK
+MAC: RCVBIN,2,false,,0.00,0.00
+MAC: END
On duty cycle expiry (4480 ms after the Tx), channels become available:
+MAC: RCH,0,,,,,0,0
+MAC: RCH,1,,,,,0,0
+MAC: RCH,2,,,,,0,0

7.8 AT+MAC=RCVTXT

Register for receiving downlink frames on specified port, payload is output as text string (translation to binary hexa string is not performed).

AT+MAC=RCVTXT,<port>

This command is no more required because all downlink frames are routed on serial link except when the port is used by an embedded application.

By default, downlink payload are processed as binary payload, thus if the AT client application needs to receive the payload as text (without any binary hexa string translation), it must uses this command.

7.8.1 Response

OK if MAC is ON and port is valid and free.

ERROR if MAC is OFF or port is invalid or port is already used by an embedded application.

7.8.2 Unsolicited Response

+MAC: RCVTXT,<port>,<more>,<textpayload>,<rssi>,<snr>

When <more> is true, it means that more downlink frames are pending in MAC server. If piggyback setting is disabled and device class is A, LoRa™WAN layer will automatically poll the server to receive more downlink frames.

7.8.3 Example

AT+MAC=RCVTXT,2
OK

Then when a frame is received on port 2 and more downlink frames are pending:

+MAC: RCVTXT,2,true,HELLO WORLD,-43.00,7.00

7.9 AT+MAC= STOPRCV

Unregister for receiving downlink frames on specified port.

AT+MAC=STOPRCV,<port>

7.9.1 Response

OK if MAC is ON and port is valid.

ERROR if MAC is OFF or port is invalid.

7.10 AT+MAC=SNDLCR

Send a Link Check Request.

AT+MAC=SNDLCR,<nb_tx>,<add_tx_rx_info>

<nb_tx> = 0 means the LCR message is sent in unack mode on port 0.

<nb_tx> != 0 means the LCR message is sent in ack mode on port 0. Since LoRaWANV1.0.4 the <nbtrans> parameter is also used in acknowledged mode (see RDR/SDR commands), thus if <nb_tx> <= <nbtrans> then the frame will be sent <nbtrans> times, if <nb_tx> > <nbtrans> then the frame will be sent 2*<nbtrans> times, ...

if <add_tx_rx_info> > 0 then for each transmission performed and each Rx performed the following responses are sent after the +MAC: <margin>,...

+MAC: TXINFO,<tx_index>,<tx_freq>,<toa>

+MAC: RXINFO,<rx_index>,<rx_freq>,<toa>

7.10.1 Response

OK if MAC is ON and Link Check Answer has been received.

ERROR if MAC is OFF or Link Check Answer has not been received and Tx was in unack mode.

ERROR NOACK if Link Check Answer has not been received and Tx was in ack mode.

ERROR also if SIGFOX™ stack is using the radio.

Received data is sent back as

+MAC: <margin>,<gwcnt>,<rssi>,<snr>

7.10.2 Example

AT+MAC=SNDLCR
+MAC: 20,3,-45.00,8.00
OK

7.11 AT+MAC=RCH

Read MAC channels command.

AT+MAC=RCH,<chan>,<page>,<unsol_evt>

<chan> specifies the channel to read (all channels of the page if omitted or if 16)

<page> specifies the channel page (all pages if omitted or if number of available pages returned by AT+MAC=? response).

<unsol_evt> specifies which unsolicited events are required (0 when no event required). The unsolicited events inform the AT client application when a MAC parameter has been changed by the LoRa™WAN layer.

When <unsol_evt> length is less than 4 digits then the old meaning is decoded (0: no event, >0: all events except the transaction end event)

When <unsol_evt> length is coded on 4 hexa digits then it is decoded as the following bit field:

bit0: registration to +SND: <busytime> event

bit1: registration to +MAC: RCH,<chan_idx>,,,,,<busytime>,<page> event

bit2: registration to +MAC: SCH,<chan>,<frequency>,<mindr>,<maxdr>,<dutycycle>,<busytime>,<page>,<rxw1freq> event

bit3: registration to +MAC: RDR,<dr>,<txpwr>,<chanmask>,<chanmaskctrl>,<nbtrans>,<eirp>,<updwell>,<dwdwell>,<antennagain> event (<eirp>, <updwell>, <dwdwell> and <antennagain> parameters are present only in case of Asian band firmware)

bit4: registration to +MAC: RTI,<rxw1>,<rxw2>,<symbtimeout> event

bit5: registration to +MAC: RRX,<rx2frequency>,<rx2dr>,<rx1droffset> event

bit6: registration to +MAC: RVAR,,,<aggregateddc> event

bit7: registration to +MAC: END event

7.11.1 Response

OK if parameters are syntactically correct.

For each channel, the following information is output:

+MAC: <chan>,<frequency>,<mindr>,<maxdr>,<dutycycle>,<busytime>,<page>,<rxw1freq>

<chan>: the channel index in the page (0 to 15).

<frequency>: the frequency in Hz (0 means channel is disabled).

<mindr>: minimum datarate allowed on the channel.

<maxdr>: maximum datarate allowed on the channel.

<dutycycle>: restricted duty cycle assigned to the channel (applies only when more restricted than ISM regulation specification).

<busytime>: time in ms before the channel can be used again for Tx (due to duty cycle restrictions).

<page>: channel page (0 to number of available pages returned by AT+MAC=? response).

<rxw1freq>: frequency used to open Rx window 1. 0 means same frequency as <frequency> parameter (available only from LoRa™WAN V1.0.2, if the parameter is absent in the response, it means the firmware version is older).

7.11.2 Unsolicited response

The unsolicited response below is sent when <busytime> changes and AT client application has registered to receive unsolicited events (see AT+MAC=RCH command).

+MAC: RCH,<chan>,,,,,<busytime>,<page>

OK

7.12 AT+MAC=SCH

Set MAC channel command.

AT+MAC=SCH,<chan>,<frequency>,<min_dr>,<max_dr>,<dutycycle>,<page>,<rxw1freq>

Only modified parameters can be specified.

Written parameters are not saved in file system, thus they are lost after a new MAC OFF/ON or a device reset.

The parameter list can be found by AT+MAC=SCH? command.

<dutycycle> is applied only if it is more restricted than the ISM regulation specification. 1 means 100%, 10 means 10%, 100 means 1%, ...

<rxw1freq> is available only from LoRa™WAN V1.0.2

7.12.1 Response

OK if parameters are syntactically correct.

7.12.2 Unsolicited response

The unsolicited response below is sent when LoRa™WAN layer modifies a channel and AT client application has registered to receive unsolicited events (see AT+MAC=RCH command).

+MAC: SCH,<chan>,<frequency>,<mindr>,<maxdr>,<dutycycle>,<page>,<rxw1freq>

7.12.3 Example

To modify channel 0:

AT+MAC=SCH,0,868100000,SF12BW125,SF7BW125,100,0,0
OK

7.13 AT+MAC= RDR

Read current MAC datarate command.

7.13.1 Response

Always OK.

+MAC: <dr>,<txpwr>,<chanmask>,<chanmaskctrl>,<nbtrans>,<eirp>,<updwell>,<dwdwell>,<antennagain>

<chanmask> is coded on 4 hexa digits for each channel page (when region has 1 channel page (EU, AS, RU) it is coded on 4 hexa digits, when region has 5 channel pages (US) it is coded on 20 hexa digits)

<eirp>, <updwell>, <dwdwell> and <antennagain> parameters are present only in case of Asian band firmware

7.13.2 Unsolicited response

The unsolicited response below is sent when current datarate changes and AT client application has registered to receive unsolicited events (see AT+MAC=RCH command).

+MAC: RDR,<dr>,<txpwr>,<chanmask>,<chanmaskctrl>,<nbtrans>,<eirp>,<updwell>,<dwdwell>,<antennagain>

7.13.3 Example

AT+MAC=RDR
+MAC: SF12BW125,11,001F,0,0
OK

7.14 AT+MAC=SDR

Set MAC data rate command.

AT+MAC=SDR,<dr>,<txpwr>,<chanmask>,<chanmaskctrl>,<nbtrans>,<eirp>,<updwell>,<dwdwell>,<antennagain>

Only modified parameters can be specified.

Written parameters are not saved in file system, thus they are lost after a new MAC OFF/ON or a device reset.

Set the data rate, Tx power and number of transmissions for uplink transmission (applied to all channels compatible with the datarate). <nbtrans> applies to unconfirmed and confirmed transmissions.

<chanmask> and <chanmaskctrl> specify the channels usable for uplink access.

<chanmask> is coded on 4 hexa digits for each channel page (when region has 1 channel page (EU, AS, RU) it is coded on 4 hexa digits, when region has 5 channel pages (US) it is coded on 20 hexa digits)

The parameter list can be found by AT+MAC=SDR? command.

<eirp>, <updwell>, <dwdwell> and <antennagain> parameters are present only in case of Asian band.

Programmed Tx power = <eirp> - 2*TxPower - <antennagain> (TxPower is described in LoRaWANRegionalParameters specification: 0=>MaxEIRP, 1=>MaxEIRP-2dB, ...)

Because of SX1272 hardware, Tx power = 13 dBm is never programmed, 14 dBm is set instead.

Thus when <eirp> = 16 and <antennagain> = 3 then computed Tx power = 13 dBm but programmed Tx power = 14 dBm

The maximum Tx power supported by the standard version of MM002 is 14 dBm, so when (<eirp> - <antennagain>) > 14 dBm then 14 dBm is programmed

7.14.1 Response

OK if parameters are syntactically correct.

OK

7.16 AT+MAC= STI

Set MAC time information command.

AT+MAC=STI,<rxw1>,<rxw2>,<symbtimeout>

Only modified parameter can be specified.

Written parameters are not saved in file system, thus they are lost after a new MAC OFF/ON or a device reset.

The parameter list can be found by AT+MAC=STI? command.

The parameters <rxw1> and <symbtimeout> are common to all channels.

The <rxw2> parameter is no more used because <rxw2> value is set to <rxw1> value + 1000 ms. It is still present for compatibility with old devices.

OK

7.23 AT+MAC=RADR

This command is used to read the current LoRa™WAN ADR, piggyback and back-off states.

The ack mode retransmission back-off procedure was initially linked to ADR bit. When ADR bit was on/off, the back-off procedure was on/off. From now, the back-off procedure is linked to the back-off state, it allows to enable ADR bit without enabling the back-off procedure. If <backoff> parameter is absent in RADR response, it means that back-off procedure is still linked to ADR bit (older firmware version).

7.23.1 Response

Always OK.

+MAC: <adr>,<piggyback>,<backoff>

<adr>, <piggyback> and <backoff> values: true or false.

7.25 AT+MAC=RDEVUID

Read device unique identifier.

Device UID is coded on 8 bytes.

This command obsoletes AT+MAC=DEVUID command.

Old command still works and returns the same response.

7.25.1 Response

Always OK

UID is returned as

+MAC: <devuid>,<rand_seed>,<read_only>

When read_only value is 1, it means that the device unique identifier is built from Nemeus 36 bits OUI (70B3D5326xxxxxxx). In this case the device UID can’t be modified and the security keys are not readable. <read_only> is always 1 in this version

7.25.2 Example

AT+MAC=RDEVUID
+MAC: 70B3D53260008982,50008982,1
OK

7.26 AT+MAC=RDEVADDR

Old command still works and returns the same solicited response.

Warning: unsolicited response changed, old one is no more sent!!!

7.26.1 Response

Always OK

Address is returned as

+MAC: <devaddr>,<networkid>

In ABP mode, the device address is the 4 LSB of the device unique identifier.

In OTAA mode, the device address is assigned by the network.

7.26.2 Unsolicited response

The unsolicited response below is sent when device is in OTAA mode and at least one AT+MAC=? command has been sent.

After receipt of valid join accept, unsolicited response is sent:

+MAC: RDEVADDR,0870C367,010203

7.27 AT+MAC=SDEVADDR,

This command is used to modify device address when ABP mode is used.

AT+MAC=SDEVADDR,<devaddr>

If MAC layer is on in ABP mode, a MAC off/on is automatically performed.

7.27.1 Response

OK if <devaddr> length is 8 characters.

7.27.2 Example

AT+MAC=SDEVADDR,01020304
OK

7.28 AT+MAC=RAPPUID

Read join server Unique ID.

Join server UID is coded on 8 bytes.

By default it is set to 70B3D53260000100.

It can be modified by sending the following AT command:

AT+GA=DIND,1,8301000008xxxxxxxxxxxxxxxx0000

Where xxxxxxxxxxxxxxxx is the new application UID LSB first.

MAC layer must be restarted to take into account new application UID (AT+MAC=OFF and AT+MAC=ON).

Join server UID can also be modified using AT+MAC=SAPPUID,<join_server_uid>.

This command obsoletes AT+MAC=APPUID command.

Old command still works and returns the same response.

7.28.1 Response

Always OK

Join server UID is returned as

+MAC: <join_server_uid>

7.28.2 Example

Read default join server UID:

AT+MAC=RAPPUID
+MAC: 70B3D53260000100
OK

Set join server UID to FEDCBA9876543210:

AT+GA=DIND,1,83010000081032547698BADCFE0000
OK

Restart MAC layer:

AT+MAC=OFF
OK
AT+MAC=ON
OK

Read new join server UID:

AT+MAC=RAPPUID
+MAC: FEDCBA9876543210
OK

7.29 AT+MAC=SAPPUID,

This command is used to modify join server UID.

AT+MAC=SAPPUID,<join_server_uid>

If MAC layer is on in OTAA mode, a MAC off/on is automatically performed.

7.29.1 Response

OK if <join_server_uid> length is 16 characters.

7.29.2 Example

AT+MAC=SAPPUID,0102030405060708
OK

7.30 AT+MAC=RAPPKEY (no more supported)

This command is no more supported !!!

7.30.1 Response

Always ERROR because device UID is read only.

7.30.2 Example

AT+MAC=RAPPKEY
ERROR

7.31 AT+MAC=RNSKEY (no more supported)

This command is no more supported !!!

7.31.1 Response

Always ERROR because device UID is read only.

7.31.2 Example

AT+MAC=RNSKEY
ERROR

7.32 AT+MAC=RAPPSKEY (no more supported)

This command is no more supported !!!

7.32.1 Response

Always ERROR because device UID is read only.

7.32.2 Example

AT+MAC=RAPPSKEY
ERROR

7.33 AT+MAC=RMC

Read MultiCast parameters.

7.33.1 Response

OK when the command is supported by the firmware.

ERROR when it is not supported.

Multicast parameters are returned as

+MAC: <addr>,<addr_mask>,<group_mask>,<fcnt_dw>,<net_skey>,<app_skey>

 - <addr>: the multicast address (32 bits)
 - <addr_mask>: the significant part of the multicast address (More Significant bits) coded on 32 bits.
 - <group_mask>: the groups the device can receive (32 bits => groups 0 to 31).
 - <fcnt_dw>: the current value of the downlink frame counter (32 bits).
 - <net_skey>: the network security key for integrity checking (128 bits).
 - <app_skey>: the application security key for payload ciphering (128 bits).

The address mask specifies which part of the received address is processed as an address and which part is processed as a group. The address mask can take the following values:

 - 0x00000000: the multicast function is disabled
 - 0xFFFFFFFF: only 1 group is possible
 - 0xFFFFFFFE: 2 groups are possible
 - 0xFFFFFFFC: 4 groups are possible
 - 0xFFFFFFF8: 8 groups are possible
 - 0xFFFFFFF0: 16 groups are possible
 - 0xFFFFFFE0: 32 groups are possible

7.33.2 Example

AT+MAC=RMC
+MAC: 789ABCDE,FFFFFFFC,00000007,0,0102030405060708090A0B0C0D0E0F00,0102030405060708090A0B0C0D0E0F00
OK

With such parameters, the following received addresses are processed:

 - 0x789ABCDC: valid multicast address, group 0 is accepted because bit0 of group mask is set
 - 0x789ABCDD: valid multicast address, group 1 is accepted because bit1 of group mask is set
 - 0x789ABCDE: valid multicast address, group 2 is accepted because bit2 of group mask is set
 - 0x789ABCDF: valid multicast address, group 3 is rejected because bit3 of group mask is not set

When the address is accepted (valid multicast address and accepted group) then the MIC is computed thanks to network security key. If the computed MIC matches with the received MIC then the payload is deciphered thanks to application security key and the resulting payload is pushed to the application addressed by the LoRa™WAN port.

7.34 AT+MAC=SMC

Set MultiCast parameters.

 AT+MAC=SMC,<addr>,<addr_mask>,<group_mask>,<fcnt_dw>,<net_skey>,<app_skey>

See AT+MAC=RMC for parameter description.

The multicast parameters are not saved in non volatile memory, thus they are lost after a cold reset (reset pin or power-cycle).

7.34.1 Response

OK when the command is supported by the firmware and the parameters are valid.

ERROR when it is not supported or parameters are invalid (especially <group_mask> parameter which can take 7 different values).

7.34.2 Example

AT+MAC=SMC,789ABCDE,FFFFFFFC,00000007,0,0102030405060708090A0B0C0D0E0F00,0102030405060708090A0B0C0D0E0F00
OK

7.35 AT+MAC=SNDDTR

Send a Device Time Request.

AT+MAC=SNDDTR,<nb_tx>

<nb_tx> = 0 means the DTR message is sent in unack mode on port 0.

<nb_tx> != 0 means the DTR message is sent in ack mode on port 0. Since LoRaWANV1.0.4 the <nbtrans> parameter is also used in acknowledged mode (see RDR/SDR commands), thus if <nb_tx> <= <nbtrans> then the frame will be sent <nbtrans> times, if <nb_tx> > <nbtrans> then the frame will be sent 2*<nbtrans> times, ...

7.35.1 Response

OK if MAC is ON and Device Time Answer has been received.

ERROR if MAC is OFF or Device Time Answer has not been received and Tx was in unack mode.

ERROR NOACK if Device Time Answer has not been received and Tx was in ack mode.

ERROR also if SIGFOX™ stack is using the radio.

Received data is sent back as

+MAC: <epoch_sec>,<epoch_frac_sec>

7.35.2 Example

AT+MAC=SNDDTR
+MAC: 1299856311,60
OK

7.36 AT+MAC=RCTX

AT+MAC=SCTX,0
OK

7.38 Informative examples

7.38.1 Device start

AT client application can detect a device start or restart when the unsolicited response +DEBUG: START,<version> is received. Depending on initialization timing, AT client application is not sure to receive this unsolicited response, that’s the reason why it is recommended that AT client application use AT+MAC=? command to synchronize with the device.

OTAA case:

+DEBUG: START,nemeus-mm002-21W21_00-modem
AT+MAC=?
+MAC: ON,V3,A,1,8,0,0.1.0.0,1.0.4.0,1.0.1.0 
OK
AT+MAC=RDEVADDR
+MAC: 00000000,000000 
OK
+MAC: RDEVADDR,0870C367,010203

The device is ready to send uplink frames.

ABP case:

+DEBUG: START,nemeus-mm002-21W21_00-modem
AT+MAC=?
+MAC: ON,V3,A,1,8,0

8 AT SIGFOX™ commands

These commands are available only on Nemeus modules embedding SIGFOX™ library. If the library is not embedded then ERROR is returned.

3 type of AT strings are specified:

SF commands: AT+SF=<cmd>,<param1>,…,<paramN>.
SF solicited responses: +SF: <param1>,…,<paramN>. These responses are sent in response to SF commands, just before the OK response, that’s the reason why the <cmd> is not present in the solicited responses. Several solicited responses may be sent between the SF command and the OK response.
SF unsolicited responses: +SF: <cmd>,<param1>,…,<paramN>. These responses are not necessarily sent between the SF command and the OK response, that’s the reason why the <cmd> is present in the unsolicited responses.

When an AT client application just need to send and receive frames, the following commands are used:

AT+SF=? to know the current SIGFOX™ layer state.
AT+SF=OFF and AT+SF=ON to stop and start SIGFOX™ layer.
AT+SF=SNDBIN,… to send uplink frame.
AT+SF=SNDBIT,… to send uplink bit.
AT+SF=SNDOOB to send uplink out of band message (keep alive messages).
+SF: RCVBIN,… when receiving downlink frames.

All other commands are not really required, they are mainly used to configure SIGFOX™ layer and to perform SIGFOX™ qualification tests.

SIGFOX™ proprietary AT command set is also supported but not described in this document.

8.1 AT+SF=HELP

This command is used to know the list of sub-commands.

8.1.1 Response

OK.

8.1.2 Example

AT+SF=HELP
+SF: <cmd>,<param_1>,…,<param_N>
+SF: <cmd> are ON,OFF,?,SNDBIN,SNDBIT,SNDOOB,SREP,RREP,STXF,RTXF,SRXF,RRXF,STXP,RTXP
+SF: <cmd>? Lists parameters of <cmd> if any
OK

8.2 AT+SF=ON

This command is used to start SIGFOX™ layer and is mandatory in order to use most of SF commands listed in this section (unless otherwise stated).

If Radio stack was ON, it is automatically set to OFF.

AT+SF=ON,<dc>,<encrypt>,<rc_sync_period>,<rc>

<dc> values: 0 means MM002 doesn't manage duty-cycle, 1 means MM002 manages duty-cycle

<encrypt> values: 0 means SIGFOX™ library doesn't encrypt the payload, 1 means SIGFOX™ library encrypts the payload

<rc_sync_period> by default, when payload is encrypted, a RC Sync frame is transmitted by the device every 4096 messages transmissions (ie. when the sequence number loops to 0) to 're-synchronize' the device with the backend. This period can be modified for test purpose, SIGFOX™ recommands to use the default value 0 which corresponds to 4096.

<rc> string values: RC1, RC2, RC3C, RC4, RC5, RC6 and RC7. Be careful, selected RC must be compatible with the module hardware version

8.2.1 Response
