Strange Data from MotionFit Board

SmartMotion® MEMS Motion Sensors

I have a brand new MotionFit board.

I see red led blinking rapidly and blue led always on.

I was able to get python up and I see data coming through my wired com port COM58.

I have not touched the motion-driver code or the python code.

When I run motion-driver-client 58
I get garbage.

The printout is extremely erratic
The cube flips all over the place due to the reported low accelerations and the extremely high gyro readings.
Whether I keep the board stationary on my table or move it around.

accel: 0.001 0.158 0.031
gyro 67.29771 1737.28244 1710.83969

I get periodic invalid packet type reports

Is my board not functioning? Please help?

Can you verify that you are running the 5.1 software for the MotionFit board? The correct software to test is included within the MotionFit SDK 5.1 zip file on the Download Page. The 4.1 version or other software releases use a different protocol header, and a mis-match causes behavior similar to the erratic jumping you describe.

yes, that was it. Documents indicate running motion-driver-client.py.

That is apparently the wrong program. The program eMPL-client.py runs.

thanks,

Richard
