MiguelHorta/Bluetooth-Library

Android library that allows you to communicate simply using a bluetooth connection.

Download

Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.MiguelHorta:Bluetooth-Library:'
	}

	dependencies {
		implementation("com.github.MiguelHorta:Bluetooth-Library:")
	}

	<dependency>
	    <groupId>com.github.MiguelHorta</groupId>
	    <artifactId>Bluetooth-Library</artifactId>
	    <version></version>
	</dependency>


                            
    libraryDependencies += "com.github.MiguelHorta" % "Bluetooth-Library" % ""


                            
    :dependencies [[com.github.MiguelHorta/Bluetooth-Library ""]]

Readme

Important

I used a BufferedReader to read data from the bluetooth socket. As I'm reading with readLine(), each message you're sending to the Android must end with a \n. Otherwise it won't be received.

The class uses listeners so everything is really easy! Enjoy :)

Install

Add to your gradle dependencies:

compile 'me.aflak.libraries:bluetooth:1.2.4'

In your Activity

Bluetooth bluetooth = new Bluetooth(this);
bluetooth.enableBluetooth();

Listener to scan and pair

bluetooth.setDiscoveryCallback(new Bluetooth.DiscoveryCallback() {

      @Override
      public void onFinish() {
            // scan finished
      }
      
      @Override
      public void onDevice(BluetoothDevice device) {
            // device found
      }
      
      @Override
      public void onPair(BluetoothDevice device) {
            // device paired
      }
      
      @Override
      public void onUnpair(BluetoothDevice device) {
            // device unpaired
      }
      
      @Override
      public void onError(String message) {
            // error occurred
      }
});

Scan and Pair

bluetooth.scanDevices();
bluetooth.pair(device);

Listener to communicate

bluetooth.setCommunicationCallback(new Bluetooth.CommunicationCallback() {
      @Override
      public void onConnect(BluetoothDevice device) {
              // device connected
      }
      
      @Override
      public void onDisconnect(BluetoothDevice device, String message) {
            // device disconnected
      }
      
      @Override
      public void onMessage(String message) {
            // message received (it has to end with a \n to be received)
      }
      
      @Override
      public void onError(String message) {
            // error occurred 
      }
      
      @Override
      public void onConnectError(BluetoothDevice device, String message) {
            // error during connection
      }
});

Connect to device

// three options
bluetooth.connectToName("name");
bluetooth.connectToAddress("address");
bluetooth.connectToDevice(device);

Send a message

bluetooth.send("message");

Get paired devices

List<BluetoothDevice> devices = bluetooth.getPairedDevices();
