Hi inti, Did you manage to connect your Fitbit accelerometer to Matlab. I tried many ways but unsuccessful. Could you please advise how you have done it.

Hey, has either of you figured out how to do it yet? I contacted the Fitbit company and they say raw accelerometer data is not accessible to anyone.

For the moment you could write an interface to libfitbit, perhaps using loadlib()

The formal FitBit API description is at https://wiki.fitbit.com/display/API/Fitbit+API

I do not see anything in the File Exchange designed to talk to FitBit devices.

Thanks for your response.

i found this script which collect and plot data from an instrument in real time at matlab ( http://www.mathworks.fr/matlabcentral/fileexchange/25519-collect-and-plot-data-from-an-instrument-in-real-time )? i think that it should just update it to work with Fitbit. what do you think about that?

thanks in advance

The protocol is not documented, so you would have to figure it out by reading the fitbitd source. The source you found was for a device that has a quite simple protocol.

I don't think there's any way for you to do that. I've been in touch with the Fitbit company and they say raw accelerometer data is not accessible to anyone. There's just no way to access it. All you have is the result of the Fitbit software's processing of the accelerometer data: number of steps, stairs climbed etc.
