Getting raw RSSI value

[Faws]

Hello!

For a project, I am relying on RSSI data from the development kit nRF52832. The problem is that the data I get is in dBm (I assume?), that is values like -30, -50 etc. I would like to get more detailed data, like decimal values of RSSI. Or even better, read raw wattage recieved on the antenna. Is this in any way possible?

Mvh

Hi,

 

RSSI is what we have available for this purpose, and here's the specs on it:

PS: dBm can be converted to watt, but the resolution on the RSSI might not meet your spec

 

Kind regards,

Håkon

Hello, and thank you for this reply.

I am familiar with using the RSSI values, but I am wondering if there is any way to get a more accurate reading? Or suppose even getting a raw measured watt without having to convert.

We do not have any other means to measure received power other than the RSSI feature of the radio.

 

Kind regards,
