Declare bluetooth permissions in AndroidManifest.xml 40 | ```xml 41 | 42 | 43 | ``` 44 | ### 2. Define SmoothBluetooth instance 45 | ```java 46 | private SmoothBluetooth mSmoothBluetooth; 47 | 48 | @Override 49 | protected void onCreate(Bundle savedInstanceState) { 50 | super.onCreate(savedInstanceState); 51 | mSmoothBluetooth = new SmoothBluetooth(Context context); 52 | } 53 | ``` 54 | there are possible overrides: 55 | ```java 56 | mSmoothBluetooth = new SmoothBluetooth(Context context, SmoothBluetooth.Listener listener); 57 | ``` 58 | or 59 | ```java 60 | mSmoothBluetooth = new SmoothBluetooth(Context context, ConnectionTo connectionTo, Connection connection, SmoothBluetooth.Listener listener); 61 | ``` 62 | 63 | `ConnectionTo` defines to what type of device to connect with (by default it is `ConnectionTo.OTHER_DEVICE` which means microcontrollers like Arduino) 64 | 65 | ```java 66 | ConnectionTo.ANDROID_DEVICE 67 | ConnectionTo.OTHER_DEVICE 68 | ``` 69 | 70 | `Connection` defines what type of connection will be (be default it is `Connection.SECURE`) 71 | 72 | ```java 73 | Connection.SECURE 74 | Connection.INSECURE 75 | ``` 76 | ### 3. Define SmoothBluetooth.Listener 77 | After that you must define `SmoothBluetooth.Listener` which catches all bluetooth related events and pass it to `SmoothBluetooth` constructor when defining its instance or if you already have `SmoothBluetooth` instance you can pass listener via setter `setListener(SmoothBluetooth.Listener listener)` 78 | 79 | ```java 80 | private SmoothBluetooth.Listener mListener = new SmoothBluetooth.Listener() { 81 | @Override 82 | public void onBluetoothNotSupported() { 83 | //device does not support bluetooth 84 | } 85 | 86 | @Override 87 | public void onBluetoothNotEnabled() { 88 | //bluetooth is disabled, probably call Intent request to enable bluetooth 89 | } 90 | 91 | @Override 92 | public void onConnecting(Device device) { 93 | //called when connecting to particular device 94 | } 95 | 96 | @Override 97 | public void onConnected(Device device) { 98 | //called when connected to particular device 99 | } 100 | 101 | @Override 102 | public void onDisconnected() { 103 | //called when disconnected from device 104 | } 105 | 106 | @Override 107 | public void onConnectionFailed(Device device) { 108 | //called when connection failed to particular device 109 | } 110 | 111 | @Override 112 | public void onDiscoveryStarted() { 113 | //called when discovery is started 114 | } 115 | 116 | @Override 117 | public void onDiscoveryFinished() { 118 | //called when discovery is finished 119 | } 120 | 121 | @Override 122 | public void onNoDevicesFound() { 123 | //called when no devices found 124 | } 125 | 126 | @Override 127 | public void onDevicesFound(final List deviceList, 128 | final BluetoothHelper.ConnectionCallback connectionCallback) { 129 | //receives discovered devices list and connection callback 130 | //you can filter devices list and connect to specific one 131 | //connectionCallback.connectTo(deviceList.get(position)); 132 | } 133 | 134 | @Override 135 | public void onDataReceived(int data) { 136 | //receives all bytes 137 | } 138 | }; 139 | ``` 140 | 141 | ### 4. Try to connect 142 | After everything is set up and all is left to do is try to connect 143 | 144 | ```java 145 | mSmoothBluetooth.tryConnection(); 146 | ``` 147 | `tryConnection()` is linked with `SmoothBluetooth.Listener` so all connection events will be passed to listener. 148 | By default if everything is ok, immediately returns all paired devices to `SmoothBluetooth.Listener`'s `onDevicesFound` 149 | 150 | ### 5. Discovering 151 | ```java 152 | mSmoothBluetooth.doDiscovery(); 153 | ``` 154 | Call `doDiscovery()` method which search for unpaired devices and returns them to `SmoothBluetooth.Listener`'s `onDevicesFound` 155 | 156 | ### 6. Sending data 157 | ```java 158 | mSmoothBluetooth.send(byte[] data, boolean CRLF); 159 | ``` 160 | or 161 | ```java 162 | mSmoothBluetooth.send(String data, boolean CRLF); 163 | ``` 164 | `boolean CRLF` indicates if data is need to be send with ending by LF and CR or not. 165 | if you do not need CRLF at the end there are some overrides with `CRLF = false` 166 | ```java 167 | mSmoothBluetooth.send(byte[] data); 168 | mSmoothBluetooth.send(String data); 169 | ``` 170 | 171 | ### 6. Disconnect 172 | 173 | ```java 174 | mSmoothBluetooth.disconnect(); 175 | ``` 176 | 177 | ### 7. Do not forget to stop 178 | For instance in your activity where `SmoothBluetooth` is defined you must call `stop()` 179 | ```java 180 | @Override 181 | protected void onDestroy() { 182 | super.onDestroy(); 183 | mSmoothBluetooth.stop(); 184 | } 185 | ``` 186 | 187 | ## Sample 188 | 189 | You can clone the project and compile it yourself (it includes a sample). 190 | [MainActivity](https://github.com/palaima/AndroidSmoothBluetooth/blob/master/app/src/main/java/io/palaima/smoothbluetooth/app/MainActivity.java) 191 | 192 | ## Contributing 193 | Want to contribute?
