Created attachment 122284 Modem manager AT commands debug
The problem I'm experiencing with this modem is the following, after being on an active session and the Network operator, for some reason, resets the connection the modem emits the unsolicited command +CGREG: 3 (Registration is rejected. The GPRS service is disabled and the ME cannot be attached to the GPRS) but ModemManager still reports the modem as connected. The only way to recover from this is to reset the modem, even after the network operator resolved the problem.
The ModemManager version is 1.4.12, running on an arch linux distribution and with a Linux kernel 4.1.19 which is running on a Raspberry PI Compute Module.
I'm sending some debug information in attached
Any help is appreciated
