AT&T QMI Cancel Location Handling

[John Marrett]

Aleksander,


What libqmi version are you using? If you're using 1.22.0, please
>> update to 1.22.2 and retest.

Sorry for the delay in getting back to you and the list. With 1.22.2 we see
debug messages but also see a change in behaviour. When receiving the
cancel location we are now seeing a termination report, the device
immediately reconnects as it should.

Can you tell me which commit is responsible for this change in behaviour? I
will consider upgrading or backporting the fix to our current release
depending on the complexity.

Thanks very much for your help, the resulting debug logs follow.
