Mike,
Thanks for the information. However, for UART communication, I used
UARTComm, not GenericComm. I dont' know whats wrong with having each component
send the same packet on each link.
I also tried as you said, i.e. putting one call in another's sendDone. That
seems to work in one case (i.e. putting DataMsg.send() in DataMsgUart.sendDone
works, but putting DataMsgUart.send() in DataMsg.sendDone() gives me packet
format error in Serial Forwarder - I may be wrong about the order, but the idea
is that only one works).
TinyOS is mystical . That's the only reason I can think of.
Again, thanks for your help.

You can only do one send() at a time using GenericComm
so call the second from the sendDone() of the first.
I just referenced my code for another of your questions
and it has an example of doing the above...
Also on the micaz/mica2 problem vis [EMAIL PROTECTED]:mica2 --
It's confusing...but the message format on the host side
is that of tos/types/AM.h, which is the "serial" format
and shared with the mica2 radio. So you need to use ":mica2"
for both platforms. The Inject problem may be because you
need to change the MOTECOM to point to serial forwarder
rather than the [EMAIL PROTECTED]:mica2. There should be an
example of the correct setting in the S.F. doc.
