Hey everyone -
I'm working on some radio code for the telosB motes. Specifically, my code
calls AMSend.send(), and via the printf library, I've proved that it returns
SUCCESS.
Unfortunately, the event for sendDone never gets called.
I've heard that this can be caused due to ack issues, so for now, I've
tossed a
#define CC2420_NO_ACKNOWLEDGEMENTS
right after my include statements.
Anyone have any other ideas of what can cause this?

{ call Leds.led2Toggle();
