M100 3G GSM Modem : Time out on command AT+CFUN 🔒

When the command AT+CFUN is run, it's possible to have a timeout.

If it is the case, you can solve it with the variable CFUNAnswertimeout that you need to increase (put 60s or more)

You can find this option:

In version 3.6 in the Alert.ini file in the section [ComOpt]

In version 4.0 directly from the system's options
