In a call service use the home assistant domain and reload config entry. Click the little load example bottom right corner to load an example of the data.
Also, in case anyone else comes across this post. The root issue is that my tp-link UB500 adapter is listed as not supported here: Bluetooth - Home Assistant
So the proper solution wold be to get a different adapter, but I am using what I have on-hand.
If you go to integrations and go to the device page for the bluetooth adapter, the last set of numbers/letters of the ip address should be the entry id.
