You may need to start GenericComm...put this in the start() and see;
call SubControl.start()
Otherwise it looks like it ought to work. When you were using the
canned examples you had working radio communication, right? If not
then you may need to check all the make options for channel and
transmit strength.

Hi;
i'm newbie at sensor nodes. I am trying to send a message and receive
it. Until now i edit examples. I tried this send, receive applications
in this examples. This is my first implementation without starting from
an example. I install this program to two nodes. Ones has timer, it
sends a message every 1 minute and it toggles red led in sendDone
function. I see the red led toggling. The other mote receive this
message.When receive this message, it must toggle green led. But it
doesn't do that.
i am sending codes, too. For the receiver node i comment "call
Timer.start(TIMER_REPEAT,1000);" line; so that its timer doesn't work.
We must do this immediately for undergraduate project. After this we
will implement a routing algorithm. Please reply ASAP.
