Hi,

I am running the MultihopOscilloscope from tinyos 2.x from CVS. I am using
Micaz motes to measure the temperature as one example. In the PC, I run
Listen.

I notice that: when I use Micaz + MTS 300, everything is ok. Listen can
display the correct sensed temperature.

However, when I use Micaz + MTS310, the sensed values are all 0.

does this mean MTS310 sensor board will not work under T2? Under T2, there
is only mts300/ directory, not mts310/

I have made sure that the sensor boards are securely attached to Micaz.

Thanks for the help,

Gary
