Hi, the default implementation of the CC2420 stack sends the acknowledgemnt frame by strobing the SACK command. Open $TOSROOT/tos/chips/cc2420/receive/CC2420ReceiveP.nc , you'll find this:
call SACK.strobe(); It is actually called only if the received frame requires an ack, if auto ack are enabled and hardware acks are disabled (in this last case, acks are sent by CC2420 without TinyOS help). Refer to the CC2420 datasheet for more details. Regards, Giuseppe On Tuesday 08 March 2011 13:08:03 Marcus Hammer wrote: > I don't get it.
