bluetoothGatt 无法连接目标 - 回调中未处理的异常

Question

我尝试使用蓝牙 GATT 服务连接我的目标设备，我在控制台中收到此消息但无法连接。

我试着用这个连接，

bluetoothGatt = mDiscoverderDevice.connectGatt(this, true, mGattCallback);

D/BluetoothGatt: connect() - device: 5D:BB:1E:F0:09:05, auto: true
 D/BluetoothGatt: registerApp()

Answer 1

我认为与BLE无关。您正在尝试从外部线程更新视图元素，如 Toast 或 TextView。这就是为什么它说 Only the original thread that created a view hierarchy can touch its views 尝试使用 runOnUIThread 方法更新 UI 视图。
