Hi,
I nee a little help / explanation on how packet acknowledgments
work? TOS 2.0, Mica2Dot I've set up my node to look for packed
acknowledgments using the ActiveMessageC module with
PacketAcknowledgements interface. I enable Ack by
call ACK.requestAck(&packet);
then perodiceally check for a response with
if(call ACK.wasAcked(&packet)) {call Leds.led0Toggle(); }
but I never seem to get a response. The other side of the radio
link is running BaseStation (unmodified). Is there something I need
to include so the basestation knows it's supposed to respond to an
ack request? Also a little explanation or a link on how this works.
To what address are you sending the packet? Broadcasts can't be acked.
Phil
