E/EasyBLE: GATT error! [status: 62, name: ISCALE, addr: 9C:9C:1F:16:C4:9A]，另外还有几个服务绑定失败的，
D/BluetoothHeadsetClient: Binding service...
E/BluetoothHeadsetClient: Could not bind to Bluetooth Service with Intent { act=android.bluetooth.IBluetoothHeadsetClient }
D/BluetoothDunImp: BluetoothDunImp checkProfileStub
D/BluetoothPbapClient: Binding service...
E/BluetoothPbapClient: Could not bind to Bluetooth Service with Intent { act=android.bluetooth.IBluetoothPbapClient }

D/BluetoothMapClient: Binding service...
E/BluetoothMapClient: Could not bind to Bluetooth Service with Intent { act=android.bluetooth.IBluetoothMapClient }
D/BluetoothDunImp: BluetoothDunImp checkProfileStub，请问这个是什么原因导致的，我运行easyble-x的demo是正常的
