Missing data

We've hit a snag... What had been working, now seems to have gone a little wrong.

We are currently investigating why we are losing data packets over the radio link. As yet we cannot be sure if this is due to a problem with transmitter or receiver. The only real change has been that the receiver is now a soldered circuit. This is a little unexpected as the fabbed board should make the receiver better, not worse. Another theory is that the transmitter is causing an issue due to it being on a breadboard either because of interference or inductance. Luckily Radiometrix have offered a loan of some evaluation kit which will pin down exactly where the problem is. Once we know which board has the problem we will know how to proceed.

Phil has bet on the receiver being faulty, whereas I think its going to be the transmitter. I hope I'm right as the fix will be simply to fab the board. If Phil happens to be right, that means we need to examine our finished receiver... not something we would want to dismantle!
