Unknown behaviour when signal quality is poor

[Alejandro Vega]

Hello !

First of all, thanks in advance for your time and dedication. I am
developing an application making use of libmm-glib high level API and
running under *ModemManager version 1.10.6*.
I am currently experiencing some trouble and I would like to know if the
behaviour of the Modem + ModemManager system is the expected one or there
is some kind of malfunction somewhere.

The problem is that we are experiencing some signal problems around an
specific area (particularly, every time that a bus passes by an area where
the signal strength is poor). I *attach *the *ModemManager debug logs* of
the outward and return journey only when the bus is passing by this area.

Regarding this, we have the following doubts:

   - Is the behaviour of the ModemManager the expected one ? Our
   application queries the ModemManager to scan for devices periodically, can
   this cause an unexpected behaviour ?
   - We are using a "global" M2M card which should be able to use different
   network operators. Is the ModemManager able to switch between operators in
   order to achieve better signal strengths ? If this is not the case, in
   order to achieve this, how would we need to proceed?

Once again,thank you very much.


Kind regards,

Alejandro Vega
