Have you checked the thing about the separator? If you don't fix it,
then ID-based sending will not work.
The reference is Federico Univesity Mobilab's tutorial.
This is what I wrote in my tutorial (sorry I got lazy and just copy-pasted it)
Mac OS X is not supported by the core working group, but MobiLab has a
very good tutorial about how to install tinyos on such OS. If you use
such tutorial, there's one other line in the avr.rules that has to be
changed. Line 33, which is AMADDR=ActiveMessageAddressC\\$$addr should
be replaced for AMADDR=ActiveMessageAddressC\\never1096WritEaddr,
assuming you are using never1096WritE as the separator mentioned. If
you don't do this, ID-oriented communication based on active messages
will not work, because the node will not be assigned a active message
address. If so, a message similar to this might appear during the
(re)installation processes of a component: Could not find symbol
ActiveMessageAddressC$addr in build/mica2/main.exe, ignoring symbol.
In this case I was trying to install the component in a mica2 mote.
I don't think it is the problem, but just in case it is...
