[Tinyos-help] Acknowledgments and base station

[Oussama Chougna]

Hi,

I'm using the CC2420Basestation, but i don't get the acks back to my sending
mote. I check acks on the mote like this:

	event void AMSend.sendDone( message_t * thisMsg, error_t error )
	{
	 	if (call ack.wasAcked(thisMsg))
	 	{
	 		//it is acked
	 	}
	 	else
	 	{
	 		//no ack received
	 	}

Is to early to check it in the sendDone event?
The same is done in one of the test applications (TestAcks) which belong to
the TinyOS2 tree.

Thank you

If your base station uses the CC2420 radio, you can use the
BaseStationCC2420, 
which turns on auto acknowledgments in the radio hardware.
