Hi Ricardo
i have the same problem in that TestSerial lesson !
evethough i have that problem i get some connection with the mote by doing this:
$make telosb reinstall .... (to install TestSerial in the mote)
$java net.tinyos.tools.listen -comm serial@<port>
and then i start to read, what i think its the message sent by the mote to
<port>
its something like this
serial@/dev/ttyUSB0:115200: resynchronising
00 FF FF 00 00 02 00 89 04 5A
00 FF FF 00 00 02 00 89 04 5B
...
can anyone please commentate this results?
thanks!

Subject: [Tinyos-help] TestSerial Strange Error
Hello everyone,
I'm going to start programming in tinyos, and I am now interested in knowing
how to debug this kind of devices.
I am working with the "ICradio stick 2.4", and I'm trying to run the
application TestSerial.
I can compile and flash .hex the mote, but when I try to run the java
application gives me an error NullPointerException.
I am working with the cygwin and tinyos-2.0.2-2. I am running the application
with the command $java TestSerial -comm COM3. I confirmed that the mote is
connected to COM3.
$ java TestSerial -comm ser...@com3
Exception in thread "main" java.lang.NullPointerException
at java.util.Hashtable.get(Unknown Source)
at net.tinyos.packet.Platform.get(Platform.java:23)
at net.tinyos.packet.BuildSource.decodeBaudrate(BuildSource.java:201)

at net.tinyos.packet.BuildSource.makePacketSource(BuildSource.java:138)
at net.tinyos.packet.BuildSource.makePhoenix(BuildSource.java:87)
at TestSerial.main(TestSerial.java:97)
Does anyone know the cause of the problem and/or how to solve it?
Thank you very much,
