Hi all,
Thanks for the reply, I really appreciate it.
Just to clarify a few things:
1) The little black switch is off.
2) I programmed it currently with Surge, so that I can test serialForwarder. (I
had programmed it with my stuff earlier).
3) I also tried on mica2 platform, same problem but a little different.
First, I tried the command
java net.tinyos.sf.SerialForwarder -comm serial@/dev/ttyS0:mica2
or java net.tinyos.sf.SerialForwarder -comm serial@/dev/ttyS0:57600
Both case serialForwarder did not report "write failed" as that in micaz case,
nothing was read from the motes and the topology info does not show up in the
java surge view either.
Next, I used the following command to specify the baudrate to 19200,
java net.tinyos.sf.SerialForwarder -comm serial@/dev/ttyS0:19200
It will report "write failed", so this at least verified that serialForwarder
will respond to wrong baudrate setting, now it seems the reading part is a
problem. Any suggestions?
Thanks many!
-Ping

in serialForwarder
If it wasn't OFF, he wouldn't have been able to program the mote in the
first place... However, if he's testing his motes out-of-the-box (they're
shipped with Surge installed) this could be the case.
