[Tinyos-help] How to find Noise floor

[Kevin Boucher]

Hi..I am pretty new to tinyos...so please dont mind this dumb question:

I am able *to* *find* the RSSI value of the received packet. Could anyone
please tell me *how* *to* *find* the *noise* *floor???

*Currently, when no node transmits, I get no RSSI Value.

Any help would be great.

Thanks.
