It seems like I am getting all the MTS400 data, and that there should be
a separate packet with the GPS data which, if is 0x0a packet is the
heartbeat, never arrives.

IIRC, the 0x0a packet is the heartbeat (health) packet that
motes send indicating they're alive. Might be that XListen won't parse
it but it's not the source of your problem. The parsed packet also looks
odd, considering there should be some GPS info. Although it reads
MTS420, is the MTS400 app sending all required data?
Sorry, haven't used MTS420 but wrote just to give something to

In my previous message, I had mentioned that I was using XListen
with a CrossBow MTS420 mote and wasn't getting any output on the screen.
As it turns out, my sensor board was faulty. I'm using another one now,
and I get readings from all the other sensors, but nothing from the GPS.
I have installed the XSensorMTS400 app on the board, and am using TinyOS
1.x. This is the output I get:
error: no packet handler for tos type 0x0a
MTS420 [sensor data converted to engineering units]:
health: node id = 2
battery: = 3278 mv
humidity: = 28 %
Temperature: = 25 degC
IntersemaTemperature: = 24 degC
IntersemaPressure: = 1011 mbar
Light: = 4.600000 lux
X-axis Accel: = 616.666667 mg
Y-axis Accel: = 116.751269 mg
I'm guessing that the line "error: no packet handler for tos
type 0x0a" might be the problem, but I have no idea how to fix it. Any
help would be highly appreciated!
