Table 9. COMMANDS

Command

Name

Description

AT

Dummy Command

Just returns ‘OK’ and does nothing else. Can be used to check

communication.

AT$SB=bit[,bit]

Send Bit

Send a bit status (0 or 1). Optional bit flag indicates if AX−SIP−SFEU

should receive a downlink frame.

AT$SF=frame[,bit]

Send Frame

Send payload data, 1 to 12 bytes. Optional bit flag indicates if

AX−SIP−SFEU should receive a downlink frame.

AT$SO

Manually send out of band

message

Send the out−of−band message.

AT$TR?

Get the transmit repeat

Returns the number of transmit repeats. Default: 2

AT$TR=?

Get transmit repeat range

Returns the allowed range of transmit repeats.

AT$TR=uint

Set transmit repeat

Sets the transmit repeat, sets only for transmit with downlink frame.

ATSuint?

Get Register

Query a specific configuration register’s value. See Table 10 “Registers”

for a list of registers.

ATSuint=int

Set Register

Change a configuration register.

ATSuint=?

Get Register Range

Returns the allowed range of the register values.

AT$IF=uint

Set TX Frequency

Set the output carrier macro channel for Sigfox frames.

AT$IF?

Get TX Frequency

Get the currently chosen TX frequency.

AT$DR=uint

Set RX Frequency

Set the reception carrier macro channel for Sigfox frames.

AT$DR?

Get RX Frequency

Get the currently chosen RX frequency.

AT$CW=uint,bit[,uint_opt]

Continuous Wave

To run emission tests for Sigfox certification it is necessary to send a

continuous wave, i.e. just the base frequency without any modulation.

Parameters:

Name

Range

Description

Frequency

800000000−

Continuous wave frequency in Hz.

999999999, 0

Use 868130000 for Sigfox or 0 to

keep previous frequency.

Mode

0, 1

Enable or disable carrier wave.

Power

0−14

Signal power setting | Default: 14

AT$CB=uint_opt,bit

Test Mode: TX constant byte

For emission testing it is useful to send a specific bit pattern. The first

parameter specifies the byte to send. Use ‘−1’ for a (pseudo−)random

pattern. Parameters:

Name

Range

Description

Pattern

0−255, −1

Byte to send. Use ‘−1’ for a

(pseudo−)random pattern.

Mode

0, 1

Enable or disable pattern test

mode.

AT$T?

Get Temperature

Measure internal temperature and return it in 1/10th of a degree Celsius.

AT$V?

Get Voltages

Return current voltage and voltage measured during the last

transmission in mV.
