I seem to have a problem with my RFM12Pi.
My current setup includes a emonTX and emonGLCD, on initial start up the RFM12Pi captures packets from both the TX and GLCD correctly, however after a couple of packets the RFM12Pi module only seems to pick up packets from the emonTX and doesnt pick up and packets from the GLCD.
Any ideas what the problem could be ?
Re: RFM12Pi missing packets
That's interesting, I am scratching my head to think of a reason why it will receive from all for a while, then from one node and not from another...
I'd try to move around the raspberrypi a bit, radio waves have their strange ways and it could be some radio shadow being cast.
Also, I'd explore the option to use ACKs on the emonGLCD, Nathan Chantrell has an excellent article on this subject, it is a 2 minute copy/paste job to add this to your firmware. http://nathan.chantrell.net/20120827/tinytx-ack-support-added/
With ACKs added, the emonGLCD will try to re-send the packages up to 5 times and wait for the RFM2Pi board to confirm receipt before it considers it lost.
