Get the RSSI value with nRF9160

[WassimZ98]

Hello. I need to calculate the RSSI value from the module nRF9160. I am using the nRF9160 DK 0.8.2. From the AT reference guide, there are two commands: AT+CESQ and AT+CSQ. The first one gives me only the RSRQ and RSRP. And the second one (CSQ) should give me the RSSI value, but it always displays 99,99.

So, is there a way to get the RSSI? 

Thanks in advance.

Hi

Here is a link to another devzone question:

https://devzone.nordicsemi.com/f/nordic-q-a/42241/nrf9160-zephyr-ncs-zte-m-nb-iot-cell-tower-rssi

RSRP is the reference signal received power (RSRP). 

example:
The last number (40) is the RSRP

>> AT+CESQ
<< +CESQ: 99,99,255,255,23,40
<< OK

This gives us -140dBm + 40 = -100dBm
