So i have two props communicating with each other over two half duplex 2.4ghz tranceivers. im using simple ide to program and full duplex serial code. the transceivers im using dont support RSSI. but i was wondering if there was some other clever way to determine signal strength? maybe using elapsed time or somthing? just curious if anyone has tried anything like this. thanks

Send a sequence of square waves at increasingly higher frequency. Measure the frequency on the receiver's data pin. At some point, it will cut out completely depending, I think, upon received signal strength.

There are several versions of that module though many of them (if not all) hide the SOC markings (sandpaper???). Seems to be a Beken BK2461, but there are more versions available (not sure yet).
T.B.D.: If its a Beken, there are chances it's another 80C51-IP, now with embodied RF.
Warning: Too many versions, though they can possibly share the same basic features (or not...).
Sorry being also plagged , due "too many copies of images inserted by &@$#***-bug". It's not my fault!!!

P.S. Corrected by hand, but needing to do it this way is not optimum!!!!!
