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.

Thanks for the answer. But I don't want RSRP, instead I am interested on RSSI.

Hi

In the latest version of the AT command Guide v1.3 the following is noted:

The +CSQ command reads 2G and 3G signal quality.

Note: Not detectable, RAT not supported. Use +CESQ and %CESQ for E-UTRA signal quality

It is not supported to read the RSSI value thus the reason why you get 99,99

from the AT command guide:
99 – Not detectable


Since the nrf9160 uses 4G (LTE-M)

Hope this explains the reason why

Jonathan

Hi Jonathan,

I assume this post is quite old but it is of use to me. I am trying to get the RSSI value through the AT command : AT+CESQ : 

+CESQ: 99,99,255,255,18,36

I get this response and I wanted to store this RSSI calculation value (36) in a variable. 
My main use is that I need to print the RSSI value explicitly and send it over MQTT. 
Could you guide me as to how to do it ? Is there a sample code that I could use for it ?

Regards,
Adeel.

Hi Adeel, 

I might suggest that you create a new Devzone case, but the asset tracker example dose use the RSRP value and sends it to the cloud, start looking at that.
