Dear all,
I am using AMSnoopingReceiverC, but the node seems only receive
message destined to the node itself, and cannot receive messages
for others.
I saw in CC2420ActiveMessageC.nc there is a comment:
"Note that snooping may not work, due to CC2420 early packet
rejection if acknowledgements are enabled."
However when I check all relevant files like CC2420CsmaC.nc,
CC2420CsmaP.nc, CC2420ReceiveC.nc, CC2420ReceiveP.nc, it appears
that the snooping function does get fulfilled.
So, does AMSnoopingReceiver really work on micaz? (TinyOS 2.x)
Dr. Levis, you wrote that comment, may you help on this question?
Many thanks!
You cannot snoop with the default T2 CC2420 stack. If you want to
snoop you have to disabled address decode, which means you do not get
synchronous acks.
