SIM900 modem usage | |
=================== | |
To enable SIM900 module support you need to put the following | |
udev rule into appropriate file in /{etc,lib}/udev/rules.d: | |
KERNEL=="gsmtty3", ENV{OFONO_DRIVER}="sim900" | |
On the i-Tetra tracking device, the SIM900 is accessed | |
via N_GSM mux device. We use ofono as SMS message | |
service and incoming voice calls service, so we | |
use /dev/gsmtty1 provided by N_GSM mux. |
