Hi
i've made a program that sends 3 messages to his neighbors, but if
i send the messages in a consecutive way , only the last message is
received. If i send the first message then wait a x'time , send the
second message and wait again the x'time, etc, the 3 messages are
received by the 3 nodes.
Sending 3 consecutive messages...
for ( NeighsPos = 0; NeighsPos < size ; NeighsPos ++) {
dbg("DominantSet","Sending Packet Neighbor Table to Neighbor %d
\n",Neighs[NeighsPos]);
call AMSend.send(Neighs[NeighsPos],&pkt,sizeof(DominantSetMsg));
}
i get in TOSSIM ...
DEBUG (2): Sending Packet Neighbor Table to Neighbor 0
DEBUG (2): Sending Packet Neighbor Table to Neighbor 1
DEBUG (2): Sending Packet Neighbor Table to Neighbor 3
Only the last Neighbor 3 receives the message. I think i know what
is the problem. Its probably because i'm not waiting for SendDone
before calling again AMSend.send. But isn't there a queue
associated with the command send? or am i wrong?
There is a queue: it's depth one. You cannot call send twice in a
row. You must wait for sendDone. You can safely call send() in the
sendDone() event. If you want a deeper queue you need to instantiate
a QueueC and probably a PoolC so you have more than one buffer.
Please read TEP 116: Packet Protocols.
