This page will summarize informations to use the GSM/GPRS module of the APF27Wireless board.
Introduction
GSM/GPRS are generally driven through the RS232 bus. AT commands are used to dialog with the module. GSM MODEM of the APF27Wireless extension board (APW) is connected to the UART5 (/dev/ttySMX4) of the APF27 module.
Linux configuration
- Linux will have to be configured in order to tell it that an APW is connected to your APF27Dev:
$ make linux26-menuconfig
System Type --->
Freescale MXC Implementations --->
...
Extension board (Wireless (APW)) --->
[*] GSM/GPRS Modem (NEW)
[ ] Bluetooth & WiFi module (NEW)
[ ] CSI (Camera) pass-through (NEW)
[ ] GPS module (NEW)
$ make linux26
- reflash you Linux kernel
Usage
Configure serial port
# stty -F /dev/ttySMX1 raw -echo -echoe -echok
AT commands
- Sending AT commands with cu utility (be sure to have installed it before):
# cu -l /dev/ttySMX1
- Check module presence
ATI3 SAGEM HiC,A.005.00 OK
- Enter PIN code
AT+CPIN="1234" OK
- Dial "123456789"
ATD"123456789"
