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 ?
The modem is still in 'radio turned on' mode, e.g. online. So as far as
oFono is concerned, nothing has changed.
As to why your context activation fails, who knows. oFono simply sends
the command to the modem. If the modem responds with an error, then you
need to figure out why that happens.
