  • SOLVED!!!!  I did not unsubscribe to the signal when switching, so the first time on ACC it was ok, then when i switched to angle the board was giving ANGLE and ACC.. so messing up data in my output...  Hope is helpfull! Thanks for the support …
    in Sensor Fusion get noisy when switching from euler angles to mag/gyro/acc Comment by ivancap December 2017
  • Yes, i get anyway all 3, it was just  an example of the data i get. It looks like the the stop of the sensor fusion is not right or the start is not right, although i cannot understand why the first time everything works perfectly.The motion in the …
    in Sensor Fusion get noisy when switching from euler angles to mag/gyro/acc Comment by ivancap December 2017
  • Hi, graph correspond to the "save" word in the sequence described. I choose ACC data, save one set of data, switched to euler angle, than back to to ACC and save the other set of data.  As you see the first is clean and seems resonable, the second …

  • Model: MetaMotion RHardware: 0.1 ModelNumber: 5 Firmware 1.3.3 Configuration of the sensor see the file code.txt inside this link  https://www.dropbox.com/s/4r00lyt10b3ozz1/MetaWareHelp.zip?dl=0 Inside there are also cvs files of data…

  • I've tried also stopping everything before closing, but i cannot understand why... 10 Hr during day goes from 99 to 96, 10 hours during night goes from 96 to 3% !! Thanks for the link.I.

  • Hi, i'm using the sensor fusion, the behavious seems the same either i stop or not the sensor before closing the app. And it is quite strange. What happens if for example:1) 9.00 AM 100% battery, not seen by bluetooth, pressed button, connected, str…

  • Hi, i'm using MetaMotion R, and yes, i disconnect and tear down the board when closing. Could it be related to the advertising timing ecc ... i'm using  p, li { white-space: pre-wrap; } mbl_mw_settings_set_connection_parameters(MWBoard, 4.f, 6.f, 10…

  • HI, yes, work on quaternion, then apply rotation, in my application i do not need to find out automatically the orientation.The applied quaternion is a rotation quaternion that rotate the versor x to z. 
    in Offset For Vertical usage Comment by ivancap May 2017
  • Ok, to other having same issue, i've used quaternion multiplication in order to rotate reference frame before getting the euler angles. And it works perfectly. Thanks.

  • Actually NDoF, but i tried every mode.

  • Ok, solved, apparently setting ACC range to 8G crates the delay, setting it to 4G or 2G is working smoothly.Maybe useful info for others. Thanks a lot. 
    in C++ Qt very slow Comment by ivancap January 2017
  • Uhm, i'll try, although i've already used the QT bt stack and streamed with another sensor at more that 60Hz. Let's see if i can solve this. Thanks anyway!

  • Hi hello, thanks for comments, and sorry for the missing axis...  the instants when the graph start changing is an abrupt rotation of ninety degree in one axis. The delay is about 80 points which correspond to about 1 second. I mean the response in …
    in C++ Qt very slow Comment by ivancap January 2017
  • It was in fact that, thanks, now the rate is much higher ... about 100 Hz, nevertheless i still experience a sort of delay from the movement to the response...  looking better it looks like when i move rapidly the device the stream is interrupted fo…
