That's an excellent idea I never thought to look for.
However, I know it's not that specific infinite loop, since the printf()
usually prints the same thing (except for the occasional bad packet?), and
that's:
Thread[Thread-1,5,main]serial@/dev/mote_ultrasound:115200: resynchronising
Attempting to send 101
RadioResource.request() returned SUCCESS
AMControl.startDone started. Parameter: 0. SendVal:101
Payload of 101 packed into message buffer at 0x38b6
AMSend.send() returned 0
AMSend.send() returned SUCCESS
Based on my code, that seems to imply it makes a success on it's first try.
Is there any profiling tool I can use on the msp430 found in the telosB,
rather than trying to tease out the error by hand?
Thanks again for your help and rapid response,
