Magnetometer data in fenix3 / vivoactive HR

Hello!

As i have seen in the AccelMag example, getting the magnetometer data is quite simple with the timer.
Is there any documentation about the maximum timer interval for such a timer to get the magnetometer data?

And the second question:
In the documentation there is the unit mGauss for these magnetometer sensor data. But i can't find any helpful information about that unit. What is this about?

    How did you get the data form the AccelMag samle code?

    I cant get it to work.

  • I believe the magnetometer provides data at 25Hz, but the minimum allowed timer value varies depending on the product and is usually around 50 ms. Our AccelMag sample uses a 100 ms timer, so that might be a good reference for you.

    We've updated the documentation now to specify "milliGauss" instead of the less conventional "mGauss", which is equal to 10^-3 Gauss.

    Is there any way to make the AccelMagtimer faster? I mean to deliver every 50ms the coordinates.
    Or is it a hardware limitation?
    Thanks
