Hi,

Does ofono support support the Telit LE920 modem ??

Do I need to change any configuration to enable the telitmodem driver
support ??

Nobody on the oFono team has this hardware.  Perhaps you can try it and 
tell us?

Hi Denis,

We have Telit LE920 modem , and working on providing support for LE920 with
ofono.It is currently not been recognized, after check_modem_list, it is
returning. Perhaps, we have to add LE920 modem specific details to ofono driver.
Can you please let us know what modem specific details we need to enter and
in which part of code/configuration files?

Thanks in advance.
Vidhya

There are two modem detection plugins at the moment.

If your modem is USB based, then plugins/udevng.c is what takes care of 
it.  Adding a new modem subtype is generally a matter of tweaking a few 
of the look up tables inside.  (e.g. vendor_list[], driver_list[], etc).

If you modem is using a Serial interface, then plugins/udev.c is used 
along with a udev rule.  See doc/calypso-modem.txt for an example of this.

Ours is USB based. We think that LE920 is taken care by gobi driver? Can you
please confirm?
If that is true, can we update the vendor id and product id of LE920 against
gobi driver structure?

Thanks for your quick reply. Appreciate your help in getting ofono working
with LE920.

I have no idea.  I thought all Telit modems utilized 27.007/27.005 AT 
commands + Telit vendor extensions.  Try contacting your vendor ?
