Hi
I try to get RSSI value for Tiny OS V1.x.
How to find Std Deviation of Gaussian Noise from it.Please help me to find.
With regards Sivasankar

Hi,
This is specific to TinyOS 2.x, this functionality was not available in
TinyOS 1.x (and XMesh). If you want to use it, you will have to either
implement it yourself (you can have a look at the TinyOS 2.x source
code) or migrate to TinyOS 2.x.
Cheers,
Urs
