Hi everyone,


I am doing some tests with Ofono.
Currently, I am trying to see if Ofono can handle an automatic data 
reconnection in case of signal loss.

I am doing the following test :
- Connect the modem to data connection via atmodem driver (so PPP link)
- Disconnect the antenna to lose signal
- Reconnect the antenna to get signal back
- Try to get data connection back

The atmodem driver is notified that the signal is lost so it disconnects 
ppp with "gprs-context.c:ppp_disconnect() Reason: 6".
After re-connecting the antenna and that the network is back, in the 
Ofono interfaces, it did not changed, I always have the 
ConnectionManager interface. The difference is that the context is not 
activated. So, I try to re-activate it but it failed with error :

gprs.c:pri_activate_callback() Activating context failed with error: 
Unknown error type

I guess that someone should have test it before me. If it is the case, 
is there something I am doing wrong ? I do not know how Ofono should 
react in this case. Maybe it should remove some interfaces ? Go in 
"offline" mode ?
If nobody tested it before, what should I look for ?


Thank you in advance for any help and Merry Christmas :)
