hi, i am working on the project where have to create the interaction of gsm m 66 with stm32 that too with the nonblocking library. can anyone suggest to me how I should start? actually, I know the diff between blocking n nonblocking and all necessities required but it first time working on gsm so don't know how I should proceed...

AT commands are just text strings - so start by getting up to speed with sending & receiving text strings.
Keep it simple to start, and just send to a terminal.
Then add receiving from a terminal.
You will also need to spend time studying your Quectel documentation - in particular, the AT Commands documentation. Practice sending commands manually from a terminal, and observing the responses on the terminal.
Take one step at a time.
EDIT - see: www.avrfreaks.net/.../1138166
There are tons of references on the interwebs to controlling GSM modems from microcontrollers.

None of this has anything specifically to do with Keil.
