An unhandled exception of type 'System.AccessViolationException' occurred in FreeFall Detector.exe
Additional information: Attempted to read or write protected memory. This is often an indication that other memory is corrupt.4

I upgraded my Nuget Package to the latest version of MetaWear.WinRT v0.7.4, and I still get this.

I start My app. See my Metaware Device (It is displayed in Green) -> Select the device --> Then hit the Back Button --> and I get this exception.

Also Get this exception on the Handlers that process the data signals for Freefall.

Please let me know how to proceed, so I do not get this exception.

Appreciate the help.

Thanks,
Rekha

    it could be that your ble connection is not properly configured for low latency response.  Try increasing the time for responses by calling mbl_mw_metawearboard_set_time_for_response before inirializing the api.

    Also, take a look at the uwp starter template for a quick way to get startedd with building a uwp app, tutorial here.

    Eric,
    I realized the problem was that I was not waiting for the board to be initialized before, I was hitting the start button. If I hit the start button after the board is initialized the system works fine. Wanted to put this out there in case it helps someone else.
