[Tinyos-help] Basic Send-Receive Problem

[Michael Schippling]

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.
