The keyboard is not functional for anything other than the test panel ("Test Input Fields") in the paring setup.

The keyboard pairs properly and I am able to type text in the test box. When pressing home, the Keyboard app shows "On".

I had originally installed the demo application. I uninstalled this and re-installed the purchased application.

It's working now. I completely de-installed and re-installed the app and the btstack daemon.

A reboot would have been sufficient. Will add that to the FAQ. Thanks
