Hello,

Have you set your Board, PAD, and SAD properly in the application? Did you press "Configure Device" before pressing the "Write" then "Read" buttons?

This error can happen mainly if you have the wrong primary address in the PAD field up near the top, so confirm that this is the same as your MAX configuration shows. You need to set the board, PAD, and SAD, then press "Configure Device". Set your send string properly, then press "Write". Finally, press "Read".

Let me know if this doesn't work for you.
