I can't figure out why I'm getting a CBManagerState of "unsupported" when I try to use Bluetooth in my app.
I checked the box that says "Uses Bluetooth LE accessories" in the Signing & Capabilities panel, and I added both of the privacy keys to my info.plist file.
When I first ran the app, it askedme whether I wanted to allow it to use Bluetooth, and I said Yes. I later confirmed that it was still set to Yes by checking the privacy screen in the Settings app.
My phone definitely supports Bluetooth, it is definitely turned on, and it works fine with other apps, including a different app that I was working on just yesterday.
There is very little documentation available for the "unsupported" state. The only other forum posts I could find turned out to be the result of someone forgetting to check the box in the project properties.
What else could cause this?
