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.

SIM800 modem usage
|
|
|
|
==================
|
|
|
|
|
|
|
|
When using sim800 modem, the udev rule is the same as the
|
|
|
|
sim900 rule :
|
|
|
|
|
|
|
|
KERNEL=="ttyS3", ENV{OFONO_DRIVER}="sim900"
|
|
|
|
|
|
|
|
Because the SIM800 and SIM900 code are the merged into one driver.
