I want some library to guide my implementation with zigbee wireless received strength signal RSS. Any standard or class code will help. I focusing in arduino platform (xbee modules).

According to the XBee manual, RSSI is measured in dBm (decibels referenced by milliwatt). To my knowledge there are no RSSI-specific libraries or methods.

Here's an Arduino library for communicating with ZigBee/XBee: xbee-arduino

I know about xbee. RSSI measurements are treated as a unsigned byte there. What I want to know is if some library implementing a way to treat it outside the xbee or if have some library-methods to use with this measurements. – Vinicius Dec 02 '11 at 21:09

This is not a direct answer to your question, but hopefully a pointer to where you'll find an answer. The XBee Series 2 uses a Ember EM250 ZigBee/802.15.4 transceiver chip. The RSSI value from the XBee module is very likely to be the value returned from that transceiver chip. The chip data sheet is here: http://www.ember.com/pdf/120-0082-000_EM250_Datasheet.pdf Doing a search on Ember's website for "RSSI" and "LQI" also throws up other documents which might help.

A received strength signal indicator is in arbitrary units, and is basically only useful as a relative measure for comparing identical hardware.
In an IEEE 802.11 system RSSI is the relative received signal strength in a wireless environment, in arbitrary units.enter link description here
It's may be useful as a debug tool by developers, but is usually not useful for the application code itself. I can't imagine a library would be useful here. What exactly would you want a library to do with this value?
