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 On Fri, Apr 18, 2008 at 10:14 AM, Michael Schippling <[EMAIL PROTECTED]> wrote: > If you are using the same hardware/software and getting 0 readings for > only some of the motes you may have hardware issues.
