阅读更多关于 Android Beacon Library - correct use of BluetoothMedic?

问题 I have some questions on the use of Bluetooth Medic, based on the following observations. Because Bluetooth stops on one of my devices I have been looking at the BluetoothMedic to see whether it can help. I've looked at the debug messages and the source code.
