All I'm saying is that the BaseStation app for tinyos is agnostic to AM
types. if it's an ActiveMessage, it will handle it.
I'm not sure if it listens in on messages that are not directed to the
id of the mote it runs on, although the RadioSnoop interface is wired.
Could anyone else shed some light into this?

for a header that looks like this :
------------------------------------------------- definitions.h
#ifndef DEFINITIONS_H
#define DEFINITIONS_H
enum
{
AM_MOTE2MOTEMSG=1,
};
typedef nx_struct Mote2MoteMsg
{
nx_uint8_t nodeid;
nx_uint16_t timestamp;
} Mote2MoteMsg;
-------------------------------------------------- definitions.h
issuing this command :
$>mig c -c-prefix=MOTE2MOTEMSG_H -target=mica2 definitions.h
Mote2MoteMsg -o OUTCMoteMSG.h
will give you
OUTCMoteMSG.h and OUTCMoteMSG.c
with C functions to handle your specific message (for the mica2
platform, in this case).
Was this what you were looking for?
Best regards,
Nikos
