Mmwave Antennas in RM510QGLAAR13A01M4G

I have a quectel model: RM510QGLAAR13A01M4G_BETA_20230423A

It is in working order but I would like to understand better how metrics such as RSRP are calculated with the 4 antennas. Are they all used at the same time and the value is an average or just the best signal from the antenna with the best reception is considered?

Is there a way to make only one of the antennas active without physically blocking the other 3?

Dear @TiagoCF
Why did you use a beta firmware?

Did you use AT+QRSRP to query values?

We don’t have way to make only one of the antennas active without physically blocking the other 3.

It is what was already installed in the device as it was borrowed to my team, we also did not update it for the same reason.

No, I used only at+qeng=“servingcell”, would at+QRSRP have a difference?

Dear @TiagoCF
If you want to check the RSRP values with 4antennas, it is recommanded to use AT+QRSRP.

I have atempted to use the command. But it did not work as in the command was not recognized.

Attempted: AT+QRSRP, AT+QRSRP? and AT+QRSRP=?

Is there an error in my approach and the manual version Im using or is it possibly missing from the beta?
