Questions for the GSTATUS display information

IoT Modules MC/EM Series

Hi everyone,

I’m having some issues with the Gstatus command for the MC7354. I’m wondering if some firmware versions include the RSSI/RSRP values for RxM and RxD and others don’t. The device I’m working with currently has the output:

OK

OK

we have an issue in the field where sometimes one of the antennas will be removed and its nice to check if both antenna ports are receiving signal.

Other user can can see the rxd

Hmm ok, must not be the firmware version then. Do you know of any reason why each antenna post values wouldn’t be showing?

If it happens randomly, will it be hardware connection problem of the antenna?
