When men were real men and typed their own AT commands...
This is a short guide how to manually get GSM going.
Contents |
Requirements
- GTA01Bv2 or GTA01Bv3 with very recent u-boot bootloader, providing usbtty (serial over USB) support)
- Do not connect any debug board!
Walk-Through
Booting the system
- Make sure the rootfs you use has 'auto usb0' in /etc/network/interfaces
- Configure the host's usb0 interface to 192.168.0.200 netmask 255.255.255.0
- ssh to root@192.168.0.201
Disabling the getty
Our default images all have a getty running on /dev/ttySAC0, please edit /etc/inittab and disable the getty on that port
Reducing the loglevel
| NOTE: You don't need this in kernel builds with patchset ≥ 1288 |
To keep the kernel from writing to /dev/ttySAC0, you need to use dmesg -n1.
Powering up the GSM Modem
- verify there is no getty or any other app running on /dev/ttySAC0
root@fic-gta01:~$ lsof | grep ttySAC0
- power-up the GSM Modem
root@fic-gta01:~$ echo "1" > /sys/bus/platform/devices/gta01-pm-gsm.0/power_on
- change permissions on ttySAC0
root@fic-gta01:~$ chown uucp.uucp /dev/ttySAC0
- setup /usr/spool/uucp
root@fic-gta01:~$ mkdir /usr/spool root@fic-gta01:~$ mkdir /usr/spool/uucp root@fic-gta01:~$ chown uucp.uucp /usr/spool/uucp
- access the GSM Modem UART
root@fic-gta01:~$ cu -l /dev/ttySAC0 Connected. AT-Command Interpreter Ready OK
Using it manually
Registering with the Network
- enter the following Hardware:AT_Commands:
ATE1 OK AT+CFUN=1 ERROR AT+CPIN="...." OK AT+COPS OK
Anwering an incoming call
RING ATA OK
Dialling an outgoing call
ATD012340234;
Hanging up
ATH OK
Using gsmd
You can use the gsmd and libgsmd-util programs to have a slightly more high-level interface to the GSM Modem. It's still console based, though.
For further instructions, see gsmd
