java.lang.IllegalStateException: BT Adapter is not turned ON - When bluetooth is turned on when it was previously off #158

This is not a consistent error. It happens here and there. It feels like maybe a race condition? If bluetooth is turned off and it is turned back on, and we trigger a scan immediately, this error happens.

Hello, Please try the new version of the library, available on branch version/2. We're working on it actively and it will soon replace the current one. I hope the API will be more readable and simpler.
