EM9190/EM9191 AirPrime EM919X/EM7690 Customer Production Test Mode (attempt)

Hi
I have an EM9190 dev kit with EM9191 modem. Trying to verify that the modem is RF capable by attempting to follow the AirPrime EM919X/EM7690 Customer Production Test Mode procedure

I started out by following the procedure from section 3.2.1 . However I cant seem to get past the first command to unlock the extended AT command set

AT!ENTERCND
ERROR

AT!ENTERCND?
ERROR

Hmmm. I did not set the password previously, is there a default password?

it should be

AT!ENTERCND=“A710”

Thank you jyijyi ! :slight_smile:
