Overview

The AX−SIGFOX modules are ultra−low power module

solutions for a node on the Sigfox network with both up− and

down−link functionality. The AX−SIGFOX modules

connect to the customer application using a logic level

RS232 UART. AT commands are used to send frames and

configure radio parameters.

About the Sigfox Technology

as 902 MHz in the USA (as defined by the FCC), depending

on specific regional regulations.

Sigfox only acts as a transport channel, pushing the data

towards the customer’s IT system.

An important advantage provided by the use of the narrow

band technology is the flexibility it offers in terms of antenna

design. On the network infrastructure end it allows the use

of small and simple antennas, but more importantly, it allows

devices to use inexpensive and easily customizable

antennas.

The Sigfox protocol is compatible with existing

transceivers and is actively being ported to a growing

number of platforms.

Sigfox uses an Ultra Narrow Band (UNB) based radio

technology to connect devices to its global network. The

usage of UNB is key to providing a scalable, high−capacity

network, with very low energy consumption, while

maintaining a simple and easy to rollout star−based cell

infrastructure.

The network operates in the globally available ISM bands

(license−free frequency bands) and co−exists in these

frequencies with other radio technologies, but without any

risk of collisions or capacity problems.

Sigfox currently uses the most popular European ISM

band on 868 MHz (as defined by ETSI and CEPT) as well

(Note that the actual product comes with a metal cap)

entering Deep Sleep mode). Out−of−band messages will

therefore not be sent.

The pins states are frozen in Deep Sleep mode. The user

must ensure that this will not result in conditions at the

module boundary that draw a lot of current.

The AX−SIGFOX modules use the UART (pins

UART_TX, UART_RX) to communicate with a host and

use a bitrate of 9600 baud, no parity, 8 data bits and one stop

bit.

AT Commands

Numerical Syntax

hexdigit ::= [0−9A−Fa−f]

hexnum ::= “0x” hexdigit+

octnum ::= “0” [0−7]+

bit

optnum ::= “−1”

frame

uint

::= (hexdigit hexdigit)+

::= hexnum | decnum | octnum | binnum

uint_opt ::= uint | optnum

Command Syntax

A command starts with ‘AT’ (note that everything is case

sensitive!), continues with the actual command followed by

parameters (if any) and ends with any kind of whitespace

(space, tab, newline etc.)

Standby Mode

If incorrect syntax is detected (“parsing error”) all input

is ignored up until the next whitespace character.

Also note that any number can be entered in any format

(Hexadecimal, Decimal, Octal and binary) by adding the

corresponding prefix (‘0x’, ‘0’, ‘0b’). The only exception is

the ‘Send Frame’ command (AT$SF) which expects a list of

hexadecimal digits without any prefix.

After Power−Up and after finishing

a

Sigfox

transmission, the AX−SIGFOX modules enter Standby

mode. In Standby mode, AX−SIGFOX modules listen on

the UART for commands from the host. Also, OOB frames

are transmitted whenever the OOB timer fires. To conserve

power, the AX−SIGFOX modules can be put into Sleep

mode or turned off (Deep Sleep mode) completely.

Return Codes

Sleep Mode

A successful command execution is indicated by sending

‘OK’. If a command returns a value (e.g. by querying a

register) only the value is returned.

The command AT$P=1 is used to put the AX−SIGFOX

modules into Sleep mode. In this mode, only the wakeup

timer for out−of−band messages is still running. To wake up

the AX−SIGFOX module from Sleep mode, toggle the

UART_RX pin, e.g. by sending a break (break is an RS232

framing violation, i.e. at least 10 bit durations low). When

an Out of Band (OOB) message is due, AX−SIGFOX

modules automatically wake up to transmit the message, and

then return to Sleep mode.

Examples

Bold text is sent to AX−SIGFOX module.

Here, we execute command ‘I’ to query some general

information.

AT$I=0

AXSEM AT Command Interface

It is strongly recommended to put AX−SIGFOX modules

into sleep mode when they are not being used.

This sends a Sigfox frame containing { 0xAA : 0xBB : 0x12

: 0x34 } without waiting for a response telegram:

AT$SF=aabb1234

OK

Deep Sleep Mode

In Deep Sleep mode, the AX−SIGFOX modules are

completely turned off. Deep Sleep mode can be activated

with the command AT$P=2. To wake−up from Deep Sleep

mode the pin GPIO9 is pulled to GND.

When using Deep Sleep mode, two things should be kept

in mind:

This sends a Sigfox frame containing { 0x00 : 0x11 : 0x22

: 0x33 : 0x44 }, then waits for a downlink response telegram,

which in this example contains { 0xAA : 0xBB : 0xCC :

0xDD }.

AT$SF=0011223344,1

OK

RX=AA BB CC DD

Everything is turned off, timers are not running at all and all

settings are lost (use AT$WR to save settings to flash before

AX−SIGFOX−MODS

The ‘CB’ command sends out a continuous pattern of bits,

down. The module can be woken up by a low level on the

in this case 0xAA = 0b10101010:

AT$CB=0xAA,1

This transitions the device into sleep mode. Out−of−band

transmissions will still be triggered. The UART is powered

AT:ADC Pn[−Pn[(1V|10V)]]?

Get GPIO Pin Analog Voltage

Measure the voltage applied to a GPIO pin. The command also

allows measurement of the voltage difference across two GPIO pins.

In differential mode, the full scale range may also be specified as 1 V

or 10 V. Note however that the pin input voltages must not exceed

the range 0..VDD. The command returns the result as fraction of the

full scale range (1 V if none is specified). The GPIO pins

referenced should be initialized to analog mode before issuing this

command.

AT:SPI[(A|B|C|D)]=bytes

SPI Transaction

This command clocks out bytes on the SPI port. The clock frequency

is 312.5 kHz. The command returns the bytes read on MISO during out-

put. Optionally the clocking mode may be specified (default is A):

Note that SEL, if needed, is not generated by this command,

and must instead be driven using standard GPIO commands

(AT:Pn=0|1).

AT:CLK=freq,reffreq

Set Clock Generator

Output a square wave on the pin(s) set to T mode. The frequency of

16

the square wave is (freq / 2 ) × reffreq. Possible values for reffreq

are 20000000, 10000000, 5000000, 2500000, 1250000, 625000,

312500, 156250. Possible values if freq are 0…65535.

AT:CLK=OFF

AT:CLK?

Turn off Clock Generator

Get Clock Generator

Switch off the clock generator

Return the settings of the clock generator. Two numbers are

returned, freq and reffreq.

AT:DAC=value

Set SD DAC

Output a SD DAC value on the pin(s) set to T mode. Parameter

value may be in the range −32768…32767. The average output

17

voltage is (1/2 + value / 2 ) × VDD.

An external low pass filter is needed to get smooth output voltages.

The modulation frequency is 20 MHz. A possible low pass filter

choice is a simple RC low pass filter with R = 10 kW and C = 1 mF.
