I am using MT3000 and M2-Dev kit to use cellular network
I am using a custom apn for my cellular plan "internet.freedommobile.ca"
however, when i go underground and come out (lose cellular signal and restore), the cellular wont reconnect, i have to manually reconnect, it is very inconvenient
the auto setup also didn't work, its always connect to the wrong APN and Wrong protocol (QMI, not QCM)
Your Quectel modem has a apn list built-in, you can check this by connecting it to QNavigator.
My RM500u-CN is full of Chinese APNs.
Auto connect seems to just connect to the modem and the mt3000 awaits the configuration from the Quectel modem instead of forcing the correct mode and apn.
The meaning of automatic connection is that it polls our built-in apn
If your sim card uses a special apn
My recommendation is to use a manual connection
