What data "MPU-9150 MotionFit Wireless SDK" sends out to PC?

Please refer to the Product Brief, Application Note, and User Guide available in the Knowledge Center tab and Devveloper Kit tab. If you have further questions please ask.

i think you have the same problem like me xD
im trying to change the data output (if you look to the firmware code, there is a input handler, i think if you send an "a" you should get the accel data), the problem is it doesnt work.

so if you get it, it would be great to share it

To reach the state logic of the motion fit device, you need to address the board with "mf" over the serial port. So, to change the acceleration mode, you would transmit an "mfa"
