ZTBleManager

object ZTBleManager

This class is responsible for getting BLE device through a given MAC address or QRCode data. The class ensures that there is only one active device, as the SDK does handle only one active connection at a time for now. BLE scanning is done through this class. You can also listen for general BLE events.
