Detecting Connected Antennas

Hi,
is there a way to detect if antennas are connected to the module?
Background is, that we want to detect if both antennas are connected after production.

Is there a way to do that via software?

Regards,
Simon

can you insert a SIM to it and type AT!GSTATUS? to check?

!GSTATUS:
Current Time:  98162		Temperature: 30
Modem Mitigate Level: 0		ModemProc Mitigate Level: 0	
Reset Counter: 7		Mode:        ONLINE

RRC state:     RRC Idle

PCC RxM RSSI:  -72		RSRP (dBm):  -108
PCC RxD RSSI:  -93		RSRP (dBm):  -136
Tx Power:      --		TAC:         05DA (1498)
RSRQ (dB):     -16		Cell ID:     01921401 (26350593)
SINR (dB):      0.4

I detached one of the two antennas. Where can I see which one isn’t attached?

EDIT: Ah I see, RxM and RxD.
Is there an API for that? I coudn’t find one that will give me two different numbers

Does this help?
