I can reproduce this on an HE910 I just started testing. Basically,
the ofono cellular service never reappears to connman after connman
disconnects it.
# connmanctl technologies
/net/connman/technology/cellular
Name = Cellular
Type = cellular
Powered = True
Connected = False
Tethering = False
/net/connman/technology/ethernet

Powered = True
Connected = False
Tethering = False
# connmanctl services

*A T-Mobile cellular_310260008772362_context1
# connmanctl disable ethernet

The cellular service will never reappear.

Hello Mike,
AFAIK if you want to connman and ofono work well together, your modem must
implement set_online interface in driver.
I've posted patch for he910
https://lists.ofono.org/pipermail/ofono/2014-December/015527.html
But it works only if you have recent firmware version.

Hmm. I don't see any difference in behavior. AT+CFUN=4,0 is never sent
with or without the patch so I guess that makes sense.

I don't know what connman is doing, but this sequence should not cause
the GPRS state to be detached... What does ConnMan actually call on the
oFono side to get to this state?

So the modem reports a network detach and loss of packet switched
connection. No context activations are possible@this point. How are
you triggering this?

oFono does not do anything of its own accord. ConnMan must be asking
oFono to deactivate the context. Is this the case? Can you provide
debug logs of what is happening on ConnMan side and oFono side?

Can you elaborate?

I suspect this is a question for the connman folks.

Dear Sir,
We are using CONNMAN/OFONO for wireless communication and network management.
Whenever the connman daemon switches from cellular to wifi automatically, ofonod removes the ppp0 interface.
On the oterhway round the ofono daemon is not doing the addition of the ppp0 interface.
I have been manually activating the context for get it right.
I am using HE910 modem with ofono version 1.16.
Regards,
Ram
