MM002-xx-EU Certification for products

1 Sigfox Pre-certification

1.1 Test mode for qualification

Stack must be activated via:

AT+SF=ON

1.1.1 Uplink test mode

TST modem must have uplink and download test mode activated by the the following commands.

Cmd : AT$ST=[<count>,<period>,<channel>]<CR> : to activate the test mode :

Resp:

OK<CR>(<LF: optional>)

• count = 0..32767 or -1 : infinite loop sending user frames (count * burst of 3 frames) : default value : 10
• period = 1..255 seconds for sending test frame every period seconds : default value : 1
• channel = 0..480 or -1 : hopping activ

1.1.2 Downlink test mode

Cmd : AT$SR=<seq_number>,<channel>,<count><CR> : to activate the rx test mode :

• <seq_number> = seq number to receive permanently
• <count> = number of frame to receive 0 or 1: permanently reception.
• <channel> = 0..480 : channel arround reception center frequency where to receive

Resp :

RX=<message1><CR>(<LF: optional>)
RSSI=<rssi_value for message 1><CR>(<LF: optional>)
RX=<message2><CR>(<LF: optional>)
RSSI=<rssi_value for message 2><CR>(<LF: optional>)
….
RX=<message n><CR>(<LF: optional>)
RSSI=<rssi_value for message n><CR>(<LF: optional>)

1.1.3 Continuous wave

To run radiated tests for SIGFOX classification, continuous wave is needed (without any modulation).

Cmd : AT$CW=<frequency>,<mode>,{<optional power>} <CR>

• <frequency> = center frequency for carrier
• <mode>= 0: off 1 : on
• <power>= value in dBm optional . If power is max power = 14dBm (used for SIGFOX tests) : no need to specify it in AT command parameter.

Note: This command is mandatory for certification of your device for CE.

Resp :

OK<CR>(<LF: optional>)
