It was because I haven't sierra_net driver in my kernel.

Now ofono finds the Network interface as usb0.
But I have an error with PIN authentication, and some AT commands return
ERROR, here is a part of the log I obtain :

AT+CRSM=192,12258,0,0,255 return an error. I have tried to send "AT
+CRSM=192,12258,0,0,255" to the modem by using minicom and it returns no
error. Do you know why it returns an error when I'm using Ofono?

I have add a retry loop on "AT+CPIN?" request,@the third attempt the
request return OK but no other commands are sent.

CME ERROR 3 means 'Operation not allowed'.

And this means 'Sim Busy'

Basically what happens is that oFono is too fast.  When you try this 
with minicom the firmware had enough time to initialize, but it does not 
have the same chance (time wise) with oFono.

The modem firmware is trying to initialize its own internal state and 
throws all of these errors.  What you might need to do is to add a 
periodic query of CPIN? until that returns something other than CME 
ERROR: 14.  at_util_sim_state_query_new() does just that.  See 
plugins/zte.c or plugins/speedup.c for an example of how this is done.

-Denis

Hi Denis,

Thanks for your answer, I have used at_util_sim_state_query_new() like
in plugins/zte.c, and it works, CPIN? responds READY. 

But when I launch active-context script, I see that I get an IP address
but I lost it right after. I have try to understand the code but I don't
know why sw_gprs_deactivate_primary() is called, and why after
ofono_netreg_status_notify() is called periodically.

Here is a part of the log I obtain :

Hi,

 

I'm trying to use a Sierra Wireless MC8092 card with Ofono on an embedded
system, but Ofono fail to setup the card because there are only five
interfaces ttyUSB0 to ttyUSB4. 

I have seen in function setup_sierra (plugins/udevng.c) that Ofono expects
to have a NetworkInterface on the interface 7. 

 

Does anybody know why the MC8092 doesn't have seven interfaces? Or which of
the five interfaces could be the NetworkInterface?

 

Regards,

 

Simon Lemoine
