Hello, all
Now I am studying for Lesson 4 of TinyOS 1.x tutorial.I have two tmote sky(s)
and I also have a problem.
The file IntToRfm.nc has the line "IntToRfmM.Send -> Comm.SendMsg[AM_INTMSG];"I
consult IntMsg.h and find out the value of AM_INTMSG is 4(by default, you can
change).

Hi,
Think of AM_INTMSG as something like a port number. It does not identify
a mote. TOS_BCAST_ADDR is a broadcast address. All nodes that physically
receive the message will forward it to the application layer. You can
find more information in this paper: http://www.tinyos.net/papers/ammote.pdf
On the issue of not filtering by moteID...
T1 GenericComm on micas does, and your mod of send is correct.
However I've heard tales of that not happening on this list,
but I don't remember what combination of modules and platforms
were at issue. You could try a search and see if anything turns up.

The message of AM_INTMSG on the receiver will be handled by the
corresponding message handler, i.e., the receiver application should
have the same receiver[AM_INSTMSG]. IF you look further down, you will
find the GenericComm actually have the default interface for all the
incoming messages.
