Dear tinyOS help list,
I think my question was already aksed several times, as I think it is a very
common configuration.
I am using micaz motes together with tinyOS 2.1.1 and an eprb.
My problem is, that the motes won't communicate with each other. After a
time of debugging, I came to the conclusion, that the event:
'event message_t* Receive.receive(message_t* msg, void* payload, uint8_t
len)' is never reached.
Also the tutorial program under tos/apps/tutorial/BlinkToRadio/ won't work
for me, so I think that my Makefile or my configuration is wrong.
I will post my sources down here and I hope that someone is able to tell me
the trick, to get the example running.
I thank you very much in advance !
Regards,
Robin
