AT$TM=mode,config

Activates the Sigfox Testmode Available test modes:

0.

TX BPSK

Send only BPSK with Synchro Bit + Synchro frame +

PN sequence: No hopping centered on the TX_frequency. Config

bits 0 to 6 define the number of repetitions. Bit 7 of config defines if

a delay is applied or not between the frames in the loop

1.

TX Protocol:

Tx mode with full protocol with Sigfox key: Send Sigfox protocol

frames with initiate downlink flag = True. Config defines the number

of repetitions.

2.

RX Protocol:

This mode tests the complete downlink protocol in Downlink only.

Config defines the number of repetitions.

3.

RX GFSK:

RX mode with known pattern with SB + SF + Pattern on

RX_frequency (internal comparison with received frame

⇔ known

pattern = AA AA B2 27 1F 20 41 84 32 68 C5 BA AE 79 E7 F6 DD

9B. Config defines the number of repetitions.

4.

RX Sensitivity:

Does uplink + downlink frame with Sigfox key and specific timings.

This test is specific to Sigfox’s test equipment & software.

5.

TX Synthesis:

Does one uplink frame on each Sigfox channel to measure

frequency synthesis step

.

AT$SE

AT$TM

=3,255 indefinitely

Convenience command for sensitivity tests

AT$SL[=frame]

Send local loop

Sends a local loop frame with optional payload of 1 to 12 bytes.

Default payload: 0x84, 0x32, 0x68, 0xC5, 0xBA, 0x53, 0xAE, 0x79,

0xE7, 0xF6, 0xDD, 0x9B.

AT$RL

Receive local loop

Starts listening for a local loop.

AT$TP=repetitions

Transient power

measurements mode

Used for transmitter transient power measurements. The command

switches the transmitter ON and OFF. During ON state (pseudo )

random bit pattern is send. Repetitions is the number of performed

measurements, acceptable range is 1−255.

AT$PN=mode,repetitions

Send & Receive PN9

bitstream for BER

measurements

Available modes:

0:

send PN9 bit stream. Repetitions = 1 is required to start sending.

Repetitions = 0 stops sending

3:

receive PN9 bit stream, calculate BER with 3 digits precision

4:

receive PN9 bit stream, calculate BER with 4 digits precision

5:

receive PN9 bit stream, calculate BER with 5 digits precision

Mode = 3−5 receives the PN9 bitstream and decodes it into an actual

BER measurement. Reports the BER for each repetition.

Repetitions is the number of performed measurements, acceptable

range is 1−255. Higher precision result takes longer time to compute.

PN9 is 9−bit pseudo random binary sequence.
