According to my tests, "Location" must also be enabled on Android 12+ to list and connect BLE devices.

Enable Location sensor

So something like this is needed to ask the user to enable the location sensor:

Why don't you just try it?
But it's true, the Bluetooth permissions are now automatically requested. However, as I said (showed) above, "Location" must be requested and manually enabled (according to my tests on all Android versions).

With Android 12 and later, it should be the case that if the NoLocationNeeded designer property is checked then compiled apps should get the extra permission flags that allow the BLUETOOTH_SCAN to work without location permission per:

Of course, as we've seen with some manufacturers, they've botched the Bluetooth permission implementation on Android 12 so one's mileage may vary.

It work, but show the message to enable location even if location is enable.

I add your [Extension to check if the Location sensor is enabled] and did like the example you post, it just work perfect.
Thanks a lot
