Hello Quectel team,
We are currently working with the EG91NAXD and EG91EX LTE Cellular Module in our devices; during our validation processes we are trying to connect the cellular module to a CMW500 R&S equipment, we are using a CMX-Z01 SIM from R&S as well, but we did not get connection between both devices, the process always ends in an Authentication Failure.
Do we need to run an specific AT commands to achieve the connection between the CMW500 and our device
Notes:
- Our device has a Main MCU that sends all the AT commands through a UART interface
- If we use a global SIM we can connect to any carrier.
Your guidance will be greatly appreciated.
