BlueToothConn

Android scan bluetooth devices and connection and communication

简体中文

Usage

Init Factory

    BTHelperFactory btHelperFactory = new BTHelperFactory();
    btHelperManager = btHelperFactory.createBTManager(this);
    btHelperManager.setBtInterface(this);

Get bluetooth devices

• get bluetooth devices already bonded

    ArrayList<BlueToothBean> deviceBondeds = btHelperManager.getDeviceBonded();

• get bluetooth devices be scanned

  Through the interface callback way to obtain. Note System version greater than 6.0 requires location access to targeting

    /**
     * Has new devices all.
     *
     * @param blueToothBeens
     *         the blue tooth beens
     */
    void hasNewDevicesAll(ArrayList<BlueToothBean> blueToothBeens);
    
    /**
     * Has new device.
     *
     * @param blueToothBean
     *         the blue tooth bean
     */
    void hasNewDevice(BlueToothBean blueToothBean);

Connect device

1. start server(server should be started before client)

    btHelperManager.openBTServer();

2. client starts to connect server

    //add device to be connected
    btHelperManager.setBluetoothDeviceToConn(bluetoothDevice);
    //stop scanning
    btHelperManager.cancelDiscover();
    //start connecting
    btHelperManager.clientConnectToServer();

Send Message

• send text message

    btManager.sendTextMessage(et_detail.getText().toString().trim());

• send file message

    btManager.sendFileMessage(Environment.getExternalStorageDirectory() + "/3.png");

Issue

• disconnect() function has some problems

  It will throw a socket closed exception when you want to disconnect,due to receiving message thread uses while(true)

• The coupling between Server ,client and manager is a bit high
