Indeed, we could use for Huawei modems for instance the AT^SYSINFO
command and retrieve the sys_mode field and parse it, I have found this
in public Huawei specifications:
<sys_mode>: System mode. The values are as follows:
0 No service.
1 AMPS mode
2 CDMA mode
3 GSM/GPRS mode
4 HDR mode
5 WCDMA mode
8 CDMA/HDR HYBRID mode
Thus we can chose accordingly the drivers to create oFono atoms.
Kind regards,
Guillaume
