UUID is not going to change every time for a particular chip. So you can find the UUID using some general purpose BLE scanner app and assign it to the variable in your block and call it where ever you want within the block.

If you’re talking about the actual device, I don’t think there is, because I was looking into this some time ago and it’s a restricted permission on Android that only system apps have since Android 6.0

> “The `BluetoothAdapter.getAddress()` methods now return a constant value of `02:00:00:00:00:00`”
