version 1.6.4 running on Yocto Linux and I am using it to communicate with a Telit LE910 V2 over MBIM.<o:p></o:p> <o:p> </o:p> Rarely, when the modem is connected to the network (default bearer is connected and I can pass data), I observe a change in access technology in MM logs (from LTE or UMTS/HSDPA) and the following sequence of events occur –<o:p></o:p> <o:p> </o:p> Bearer disconnection -> Registration state change to unknown -> Attached to UMTS network -> Registration state change to home<o:p></o:p> <o:p> </o:p> After this sequence, the bearer status on MM shows that it is still disconnected and if I attempt to establish the bearer again using simple connect at this point, MM fails to connect.<o:p></o:p> Basically I want to re-establish packet service again after a change in access technology and I am not sure if the problem lies with the modem or MM.<o:p></o:p> <o:p> </o:p> So my questions is, does MM seamlessly support bringing the packet bearer back up after an access tech change or if not what steps need to be taken in order to do so?<o:p></o:p> <o:p> </o:p> Please find MM logs snippets below.<o:p></o:p> <o:p> </o:p> Thanks, Shijo<o:p></o:p> <o:p> </o:p>
