Hi,
I tried using the ReceiveMsg interface before using Receive... neither seem
to produce a positive result (i.e. - for simple testing, toggling the green
LED). If I choose to use something like:
event TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr m) {
// msg should have been received - toggle LED
call Leds.greenToggle();
return m;
}
That should work? But... it doesn't :(
Cheers,
Alex.

Hi,
Who is using this Receive interface?
The Receive interface should be called above layer2 (AMStandard).
If you are talking about using a simple send/receive application,
what you need is ReceiveMsg/SendMsg interface.
If you really want to use Receive interface, you have to signal
Receive.receive somewhere.
For example,
event TOS_MsgPtr ReceiveMsg.receive(TOS_MsgPtr msg) {
signal Receive.receive(msg, msg->data, msg->length);
return msg;
}
