    For specific details of Quectel's AT commands, you will have to study the Quectel documentation.

    As far as the STM32 (or any other microcontroller) is concerned, Quectel AT Commands are no different to any other AT Commands - so you can look at any of the huge number of AT Command examples on the interwebs...
