Based on my sigfox multi-board shield, it is possible to hack sigfox with a raspberry pi. The standard telecom Design firmware allow to use it as a modem. The raspberry Pi just have to send the expected AT commands
Configure the Raspberry-Pi
The serial port of the RaspberryPi is used for boot console and must be reconfigured to be available for application.
Edit /etc/inittab ; the last line should be
T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
add a # in front of this line to disable it
#T0:23:respawn:/sbin/getty -L ttyAMA0 115200 vt100
Then edit /boot/cmdline.txt and change the line from
dwc_otg.lpm_enable=0 console=ttyAMA0,115200 kgdboc=ttyAMA0,115200 console=tty1 ...
dwc_otg.lpm_enable=0 console=tty1 ...
Now you can reboot the raspberry Pi
Install console tool and connect
Once restarted, install minicom serial console
sudo apt-get install minicom
and launch it
minicom -b 9600 -o -D /dev/ttyAMA0
Now you can type any AT command like AT?
AT OK AT? ---------------- E => Echo I => Information Q => Quiet V => Verbose X => Extended result code Z => Reset ? => Help &F => Factory &V => Status &W => Save S200 => Reboot banner display
