BLE BluetoothGattCallback получает STATE_DISCONNECTED, когда устройство все еще включено - PullRequest

Я подключаюсь к устройству Bluetooth, используя этот метод:

/**
     * Connects to the GATT server hosted on the Bluetooth LE device.
     *
     * @param address The device address of the destination device.
     *
     * @return Return true if the connection is initiated successfully. The connection result
     *         is reported asynchronously through the
     *         {@code BluetoothGattCallback#onConnectionStateChange(android.bluetooth.BluetoothGatt, int, int)}
     *         callback.
     */


      public boolean connect(final String address) {
        if (mBluetoothAdapter == null || address == null) {
            Log.e(TAG, "BluetoothAdapter not initialized or unspecified address.");
            return false;
        }

        // Previously connected device.  Try to reconnect.
        if (mBluetoothDeviceAddress != null && address.equals(mBluetoothDeviceAddress)
                && mBluetoothGatt != null) {
            Log.e(TAG, "Trying to use an existing mBluetoothGatt for connection.");
            if (mBluetoothGatt.connect()) {
                mConnectionState = STATE_CONNECTING;
                return true;
            } else {
                return false;
            }
        }


        final BluetoothDevice device = mBluetoothAdapter.getRemoteDevice(address);
        if (device == null) {
            Log.e(TAG, "Device not found.  Unable to connect.");
            return false;
        }
        // We want to directly connect to the device, so we are setting the autoConnect
        // parameter to false.
        mBluetoothGatt = device.connectGatt(this, false, mGattCallback);
        Log.e(TAG, "Trying to create a new connection.");
        mBluetoothDeviceAddress = address;
        mConnectionState = STATE_CONNECTING;
        return true;
    }

Вот мой BluetoothGattCallback:

    private final BluetoothGattCallback mGattCallback = new BluetoothGattCallback() {
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {
        String intentAction;
        Log.e(TAG, "In onConnectionStateChange and there has been a change of :" +newState);
        if (newState == BluetoothProfile.STATE_CONNECTED) {
            intentAction = ACTION_GATT_CONNECTED;
            mConnectionState = STATE_CONNECTED;
            broadcastUpdate(intentAction);
            Log.e(TAG, "Connected to GATT server.");

            // Attempts to discover services after successful connection.
            Log.e(TAG, "Attempting to start service discovery:");
            try {
                sleep(2000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
            Boolean discover = mBluetoothGatt.discoverServices();
            if (discover == true) {
                //Raise flag
                unstableBluetoothBehaviour = true;
                Log.e(TAG, "Service discovery returns true and is started");
            } else {
                Log.e(TAG, "Service discovery returns false and has stopped unexpectedly");
            }

        } else if (newState == BluetoothProfile.STATE_DISCONNECTED) {
            intentAction = ACTION_GATT_DISCONNECTED;
            mConnectionState = STATE_DISCONNECTED;
            if (unstableBluetoothBehaviour == true) {

                Log.e(TAG, "Unstable behaviour detected");

            }
            Log.e(TAG, "Disconnected from GATT server.");
            broadcastUpdate(intentAction);
            close();
        }
    }

    @Override
    public void onServicesDiscovered(BluetoothGatt gatt, int status) {
        Log.e(TAG, "In onServicesDiscovered");
        if (status == BluetoothGatt.GATT_SUCCESS) {
            Log.e(TAG, "mBluetoothGatt = " + mBluetoothGatt);

            broadcastUpdate(ACTION_GATT_SERVICES_DISCOVERED);
        } else {
            Log.e(TAG, "onServicesDiscovered received: " + status);
        }
    }

    @Override
    public void onCharacteristicRead(BluetoothGatt gatt,
                                     BluetoothGattCharacteristic characteristic,
                                     int status) {
        if (status == BluetoothGatt.GATT_SUCCESS) {
            broadcastUpdate(ACTION_DATA_AVAILABLE, characteristic);
        }


    }

    @Override
    public void onCharacteristicChanged(BluetoothGatt gatt,
                                        BluetoothGattCharacteristic characteristic) {
        broadcastUpdate(ACTION_DATA_AVAILABLE, characteristic);
        Log.e(TAG, "Characteristic has been updated = " + characteristic);
    }


};

Проблема в том, что когда я вызываю Connect (), onConnectionChange () вызывается с STATE_CONNECTED. Затем он вызывается снова с STATE_DISCONNECTED!


Вот распечатка с Logcat , которая может помочь вам разобраться в проблеме:
