Hi everyone,
please I really need help. I’ve used a BG96 module for making a prototype that it measure different network parameters like RRSI, RSRQ, ECL, and Cell ID. All of these parameters are catched well except one, the Cell ID. The reason is because when I send the command AT+QENG=“servingcell”, the module does not respond me with all the fields of the answer, only shows me until third parameter. This is the response I received:
+QENG: "servingcell","NOCONN","CAT-NB",
After the last coma, I cannot read more, doesn’t appear. The answer I should receive is like this:
+QENG: "servingcell","NOCONN","CAT-NB","FDD",460,11,DDA1451,280,2506,5,0,0,69C9,-84,-17,-67,8,44
I don’t understand why happen this.
For more realization, I publish all the code, it is programmed on the Arduino IDE because the module is controlled by one Arduino UNO. Thanks for all.

I think it is not necessary at all, but just in case.
