Hi,
Thought I'd mention a debugging technique that I found useful and which others may also. It's often difficult to tell what's going on inside a network of motes. You can get some information by sending out RF debug messages or sending data to a UART or by blinking the LED's. These methods have their limitations. RF and UART messages are limited in how fast they can be received and how close you are to the area of interest, especially when you have a lot of senders. The LED's are only three bits of information. Another technique is to program a mote (or several of them) as probes that will light their LED's in reaction to specific events. This is especially useful for detecting the presence or absence of RF messages. You can wave your probe mote around your network and find out what is happening in the RF world. You could do the same with a basestation connected to a laptop, but the LED's on a mote are much easier to see and correlate with what the LED's on your network motes are telling you and you don't have to deal with a cable. You can also program the probe mote to light an LED under very specific conditions (i.e., "received msg and 4th data byte is 0x1c").
