Bluetooth Helper Library

中文 | English

A library makes your app's bluetooth operation(for Smart Iot Hardware especially) so easy!

Don't forget give me a star :）

Feature

• Packaged common bluetooth operations, such as device discovery, connect the remote device and more.

btHelperClient.searchDevices(listener);

• Sending messages is such as Http, you send a message to the remote device(not need to connect device firstly, such as Smart Iot Hardware) then you could get a response and a status code.

btHelperClient.sendMessage("20:15:03:18:08:63", item, true, new OnSendMessageListener() {

        @Override
        public void onSuccess(int status, String response) {
        }

        ...

});

Dependency

There are two ways:

• clone this project, and use as dependency
• just add following code to you build.gradle:

   // Add it in your root build.gradle at the end of repositories
	allprojects {
		repositories {
			...
			maven { url "https://jitpack.io" }
		}
	}
	// Add the dependency
   dependencies {
       compile 'com.github.a-voyager:BluetoothHelper:f71d40a98b'
   }

Usage

• Get the instance use a Context object to initialize

btHelperClient = BtHelperClient.from(MainActivity.this);

• Send message to the remote device send message asynchronously, callback in main thread. parameters means: device's mac address, message object, if need to obtain response, SendMessageListener.

MessageItem item = new MessageItem("Hello");

btHelperClient.sendMessage("20:15:03:18:08:63", item, true, new OnSendMessageListener() {

        @Override
        public void onSuccess(int status, String response) {
           // Call when send a message succeed, and get a response from the remote device

           // status:   the status describes ok or error.
           //           1 respect the response is valid, -1 respect the response is invalid
           // response: the response from the remote device, you can call response.getBytes() to get char[]

        }

        @Override
        public void onConnectionLost(Exception e) {
            e.printStackTrace();
        }

        @Override
        public void onError(Exception e) {
            e.printStackTrace();
        }

});

• Close connection just call close() method

    @Override
    protected void onDestroy() {
        super.onDestroy();

        btHelperClient.close();

    }

More API

• Search devices search devices with just calling searchDevices() method

btHelperClient.searchDevices(new OnSearchDeviceListener() {

        @Override
        public void onStartDiscovery() {
            // Call before discovery devices

            Log.d(TAG, "onStartDiscovery()");

        }

        @Override
        public void onNewDeviceFounded(BluetoothDevice device) {
            // Call when found a new device

            Log.d(TAG, "new device: " + device.getName() + " " + device.getAddress());

        }

        @Override
        public void onSearchCompleted(List<BluetoothDevice> bondedList, List<BluetoothDevice> newList) {
            // Call when the discovery process completed

            Log.d(TAG, "SearchCompleted: bondedList" + bondedList.toString());
            Log.d(TAG, "SearchCompleted: newList" + newList.toString());

        }

        @Override
        public void onError(Exception e) {

            e.printStackTrace();

        }

});

• Set filter use a filter to check if a given response is an expect data.

btHelperClient.setFilter(new Filter() {

       @Override
       public boolean isCorrect(String response) {
           return response.trim().length() >= 5;
       }

});
