How can I determine modem type


#1

Hi
I have some device with cellular modems.
Modems can be CDMA or GSM.
How can I determine in runtime cellular standard (CDMA or GSM) of each modem?
Is there any AT commands for this?

Thx
Best regards

Presumably, only a GSM modem will accept GSM-specific commands, and vice-versa… :question:

Simply type: AT+CSCS?
and scan the modem’s reply for “CDMA”, (6 characters)

that works for me
