I fixed the sendDone not being called problem by adding a very large meyer-heavy.txt file for noise. Now my problem is that the nodes are not receiving the messages that are being sent. I am using the suggested topo.txt file with 2 nodes:
1 2 -54.0 2 1 -55.0 I read in the TOSSIM tutorial the following: "If you set node's clear channel assessment to be at -110dBm, then nodes will never transmit, as noise and interference never drop this low." I have not set the node's clear channel assessment to anything. I have looked to see how I might do that, but did not find anything. Is it possible that this is my problem?

I am now able to see that sendDone is being called. Now the problem is that the message is not being received. I have BlinkToRadio set up with just two nodes, and they are both booting and their timers are firing, and they are both sending their messages, but none of the messages are being received. Any suggestions?

The current version of TinyOS needs it defined as in the tutorial. The old form with add(i,j,k) is not supported anymore as I found out trying to run an older program with that definition. The whole meyer-heavy.txt is in the tossim file under noise. You need more than the ten entries in the tutorial and somewhere there it is said, that you need at least 100 entries of this file. Try it with part of that file and the implementation in the tutorial, it should work. Nicole > I am trying to run the BlinkToRadio application using TOSSIM.
