    Hello Anson,

    Are you using an example from the SDK? If yes let us know which example is causing this issue. Also did you make any changes to the example, if so try to use the original example in the SDK and add small parts of the modified code to see which one is causing the issue.

    If you are not using an example in the SDK, then please see if it's possible to use an example in the SDK as a starting point and then modify it to your needs.

    If you are still having issues then please provide more details about the application and the debug steps you have taken. With the information on hand it's hard to identify the issue.

    Thanks,
    Sai
