Hello,

May I ask what device are you using?

Also, it would be great if you could attach the master API example and the screenshot of the error.

Without more detail like what device you are communicating with and showing us some of your code all we can really tell you is that you are doing something wrong.

What that is is impossible to tell with what little information we have.
