Hi,
I'm trying to send a msg from one mote to another. Mote A has a
msg in a buffer that will send to mote B. Everything works ,
except in one situation where mote A sends to mote B, but the msg
doesn't get there and consequently no ack, then in sendDone i
repost the task of the msg.
The weird thing is that when i repost the task, the addr should be
B, but for some weird reason the var addr in the repost becomes
mote A addr and enters an infinite loop.
I haven't tested this in real motes, only in tossim, here's a part
of the simulation:
Well , i found why that was happening , tks to Miguel for the help.
I was sending the msg but it never got there, nevertheless the
radio layer changed the source , and i wasn't saving the old one.
This line in SendDone solved my problem:
"call AMPacket.setSource(msg, call AMPacket.destination(msg))".
Maybe this can help anyone that may have the same/similar problem.
The radio stack would only change the source if it used the buffer to
receive a new packet. Don't forget that the reception path uses a
buffer swap. So you can't just keep a handle on the pointer, unless
you pass it a new buffer to use...
