EM20G Antenna Signal Optimization


I’m trying to find a way to optimize signal strength down to the individual antenna, or at least per antenna pair.

AT+QENG=“servingcell” Gives great information, but it does not discern between the individual antennas. Is there a way, via AT commands or otherwise, that I can get the signal information per antenna port or at least per antenna pair?

Dear Didneywhorl:
Thanks for your inquiry in Quectel forum.
For your request, you can try to use AT command AT+QRSRP, which will list the signal information per antenna. You can check to see if it’s what you need. of course, if you still have any question, you can send email to support@quectel.com to get technical support directly from our local FAE. thank you very much.

Excellent, thank you. I’ll give it a look.

When i try this command I only get an error.

Any ideas? the modem is up and working I just have never found a command that tells me Signal info.

Hi srunyon1,
It should be that this command is temporarily not supported. You can grab the qxdm log and check the signal quality of each antenna in the log, but this is more troublesome.
