I am not using BLE, just the classic BT; so I did not think the first reference applied to my problem.
Anke's solution shown in the second reference makes use of a permission that does not show up in my "call Screen1 for permission" block; so I do not know how to make use of it. Here is what my call block displays:
However, I have just seen this post from Ewan:
The BluetoothClient/BluetoothServer permission issue should be addressed on this temporary test server: http://nb190a-bugfixes.ai2-ewpatton-temp.appspot.com/
When I tried that server, the missing BLUETOOTH_CONNECT permission appeared and I could incorporate it into my code.
With that permission in code, an Android message appears on the phone and upon confirmation, the permission is granted; and the program Bluetooth features work OK.
I can generate an APK using the new server and wait till the changes appear in the live version.
