Android-EasyBluetooth

A collection of easy to use bluetooth utilities for Android.

Getting started

Simple Bluetooth SPP

Add the following line under repositories to the project root build.gradle file.

maven { url 'https://jitpack.io' }

Then add the dependency in your app build.gradle file

implementation 'com.github.KPreetham:Android-EasyBluetooth:RELEASE_VERSION'

Refer to JitPack badge above for RELEASE_VERSION.

Basic Usage

Implement dataListener.

dataListener = new SppDataListener() {
    @Override
    public void onDataReceived(byte[] data, int bytes_read) {
        // received `data` of length `bytes_read`
    }

    @Override
    public void onDataSent(byte[] data) {
        // `data` was successfully written to the stream.
    }
};

Implement connection listener

connectionListener = new SppConnectionListener() {
    @Override
    public void onConnectionSuccess() {
        // Successfully connected to bluetooth device.
    }

    @Override
    public void onConnectionFailure() {
        // Connection attempt failed.
    }

    @Override
    public void onConnectionLost() {
        // Connection is lost. Socket might have been closed abruptly.
    }

    @Override
    public void onConnectionClosed() {
        // Connection was closed succesfully.
    }
};

Create a BluetoothSpp object.

bluetoothSpp = new BluetoothSpp.Builder()
    .setConnectionListener(connectionListener)
    .setDataListener(dataListener)
    .setBufferSize(2048)
    .build();

To connect to a BluetoothDevice call connect(BluetoothDevice) on bluetoothSpp object.

bluetoothSpp.connect(device);

To disconnect

bluetoothSpp.disconnect();
