like WIFI because its also working on 2.4GHz.

To elaborate on awneil:

Any reflections will affect RSSI, if any of the devices move position then the RSSI will change due to a change in local RF environment. Also any other 2.4GHz transmitter will affect the RSSI.

Hello awneil,

[quote userid="6462" url="~/f/nordic-q-a/66033/how-to-get-stable-rssi-value/270055"]the thing is that there's a huge number of things in the environment that will cause RSSI to vary - including people moving around, etc, etc[/quote]

yes , you are right. i was trying to get not stable but near to stable like if device was in fix location then variation is not more then (+-3) to (+-5).

[quote userid="6462" url="~/f/nordic-q-a/66033/how-to-get-stable-rssi-value/270055"]you could try standard techniques such as averaging ...[/quote]

we already apply averaging.

Thank you for your reply,

the thing is that there's a huge number of things in the environment that will cause RSSI to vary - including people moving around, etc, etc

so you really can't expect the RSSI value to be steady.
