I've got a cerbo (with 2.60 f/w) and the newer LTE modem but the cerbo seems to lose the connectivity with the modem itself every day or so. When I look at the console, the message in the GSM page is "No GSM modem connected".
A reboot of the cerbo always restores the connection, so this isn't an electrical issue (USB plug being disconnected etc).
There doesn't appear to be any firmware update available/necessary for the modem.
Is it possible (I have root access enabled on the cerbo) to look at more detailed logs to help determine what the problem is?
Is this a known bug in 2.60?
Thanks for any advice.
