Hi,
Just to be more specific about the problem and steps that I am doing,
hopefully someone could point out where the problem might be.
1. Programmed surge to mote 0, 1, 2, 3 etc.
2. Connect the micaz mote 0 to MIB5100 board, the battery was taken out
from mote 0 as suggested in xbow "getting started guide". In my case, it
actually didn't matter whether I had battery or not, nor did switching
on/off mote 0 mattered either.
3. Start the serial forwarder
Listening to serial@/dev/ttyS0:micaz
Platform micaz
Listening for client connections on port 9001
serial@/dev/ttyS0:57600: resynchronising
4. Start the surge java program:
java net.tinyos.surge.MainClass 0x7d
5. If I start send root beacon from the surgejava interface, the
serialForwarder will always report "write failed", meanwhile, the packets
read count remains 0.
Cory mentioned that it might be baudrate failure, but the serialforwarder
automatically set it to be baudrate 57600, right? Whatelse could have
been wrong?
Thanks,
-T.

I haven't used MicaZ motes in Linux. Hopefully someone else can chime
in. - Cory
