Jukebox RX Help about goodwatch HOT 2 CLOSED

Howdy from Hyderabad!

I'm away from my lab at the moment, but maybe I can help with some quick advice. If not, I'll try the code when I'm back in Tennessee.

Generally, receiving is the same as transmitting, except that

(1) Your receiver bandwidth registers matter. They should be wide enough to capture the entire packet including some drift. If this is wrong you will still get some packets, but fewer than you expect.

(2) Your SFD/SYNC registers must match on the transmitted packet, and if this is wrong, you will get no meaningful messages.

(3) This protocol is OOK, so there might be something weird about the threshold between a zero and one. I've not yet implemented an OOK receiver, so I don't know for sure.

(4) Some OOK receivers are very generous about symbol length because they recover it from the start of the packet. The CC1101 core of the CC430 chip doesn't do this automatically, so you should double check that your symbol length is the same as the transmitter's. If this is wrong, you will get no packets.

(5) Always debug reception with checksumming turned off, and turn it back on only after everything else is working. If this is wrong, you will get no packets.

If this doesn't help, please tell me more about what your failures look like. That might help diagnose the problem.
