Hi,

I am working on a project where two atmega328p's running arduino boot loader communicating to each other using these:

http://www.ebay.com.au/itm/190826220938?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

One is the base unit with devices attached and the second is a handheld unit with buttons and leds to show the status of connected devices.

They say the rf units have 100m line of sight range, i am using these inside and seems to work fine but sometimes not so well, i am trying to figure out how i could measure the strength of the connection? is this possible? right now i have a script that every second pings the base unit to see if they are still in range, this seems fine but i want to learn more.

Any input would be great!
