Hi all, I ran MicaSBTest1 in the folder MicaSBVerify to verify the HMC1002 magnetometer on MTS 310CA sensor board. The sensor was placed on my desk without strong magnetic field around it. After switching my Mica2 node on, the red LED which indicates the node being self calibrated kept blinking. Swaying a magnet about the sensor didn't make the yellow LED blink or light up. It seems that the node was trying to calibrate itself, but in vain. The firmware source code comes from the latest tinyos.cvs.sf.net tinyos-1.x branch.
I also tested all 5 MTS310 sensor boards we bought with gain setting from 0 to 255, only to find that the output value of the magnetometer refused to change in response to adjustment of gain setting. The reading value from Mag.MagX and Mag.MagY typically vibrates between 60 and 80. Swaying a magnet about the sensor didn't help too. But the output value is supposed to approach 512 if the gain setting is fine tuned. Did I overlooked something?
