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/ttySMX4 raw -echo -echoe -echok

AT commands

# cu -l /dev/ttySMX4
