Eric,
I am researching TOS threading approaches. I thought I would start with
tosthreads since it is included in the distribution.

why are you using tosthreads?

I have not had success using TOSThreads to write to the Uart
interface.
So, I devised the following test.
Using tinyos-2.1.2 distribution, I performed the following test
with two
telos motes:
cd apps/tosthreads/apps/RadioStress
make install,1 telosb threads bsl,/dev/ttyUSB1
The mote's led's indicate that it is transmitting.
cd apps/tosthreads/apps/BaseStation
make install,2 telosb threads bsl,/dev/ttyUSB0
The mote's led's indicate that it is receiving.
export MOTECOM=serial@/dev/ttyUSB0:telosb
java net.tinyos.tools.Listen
Output to the console is a stream of bad packet messages:
serial@/dev/ttyUSB0:115200: bad packet
serial@/dev/ttyUSB0:115200: bad packet
...
Now, I replace the threaded version of BaseStation with the
event-based one:
cd apps/BaseStation
make install,2 telosb bsl,/dev/ttyUSB0
Output from java net.tinyos.tools.Listen now appears correct.
Can anyone confirm this behavior? Is this a known problem with the
BaseStation threads demo?
Stephen
