UDOOBluLib

Library for Udoo Blu board

Usage

Include the library as local library project or add the dependency in your build.gradle.

repositories { maven { url "http://dl.bintray.com/udooboard/maven" } }

...

dependencies { compile 'org.udoo:udooblulib:0.4.2' }
Add in your AndroidManifest.xml UdooBluService class
```
   <service
     android:name="org.udoo.udooblulib.service.UdooBluService"
     android:exported="false" />
```
This enable our app to communicate with the service that manage all the connected UDOO BLU.
Main Activity
The MainActivity must extend UdooBluAppCompactActivity. It automatically checks all the permissions (Android 6 it shows all the pop-ups), and starts the UDOO BLE service. When all these checks are done the Activity call the onUdooBluManagerReady(). In this sample we decided to start the UDOO BLU devices scan ( startScan() method ). When a new UDOO BLU is detected the Activity calls.
```
   public void onBluDiscovered(int rssi, BluetoothDevice udooBluDevice) {
       ...
   }
```

Connect ble device:

   public void onBluDiscovered(int rssi, BluetoothDevice udooBluDevice) {

   if (!isConnected) {
       connect(udooBluDevice.getAddress());
       stopScan();
       isConnected = true;
       }
   }

The connect method accept as input the device address. We can get the address by the udooBluDevice object calling getAddress() method. We can manage when the scan is terminated or it’s failed.

    @Override
    public void onBluScanFinished() {
    ...
    }

    @Override
    public void onBluScanFailed() {
    ...
    }

A UDOO BLU is connected When the connection is established the activity calls onBluConnected(final UdooBlu udooBlu) and we can work with udooBlu object.
Single pin

udooBlu.setPinMode(<PIN_NUMBER>, IOPin.MODE.DIGITAL_OUTPUT);

6.1 Multiple pins

    udooBlu.setIoPinMode(null, 
    IOPin.BuilderIOPin.IOPIN_PIN.A0,  IOPin.MODE.DIGITAL_OUTPUT),
    IOPin.Builder(IOPin.IOPIN_PIN.A2, IOPin.IOPIN_MODE.ANALOG)
    );

6.1.1 Callback mode

    udooBlu.setIoPinMode(new OnBluOperationResult<Boolean>() {
    @Override
    public void onSuccess(Boolean aBoolean) {
	...
    }

    @Override
    public void onError(UdooBluException runtimeException) {

    }
    }, 
    IOPin.Builder(IOPin.PIN.A0, IOPin.MODE.DIGITAL_OUTPUT),
    IOPin.Builder(IOPin.PIN.A2, IOPin.MODE.ANALOG_INPUT)
    );

6.2 Read digital pin 6.2.1 Single pin

    udooBlu.digitalRead(new OnBluOperationResult<Boolean>() {
    @Override
    public void onSuccess(Boolean aBoolean) {
	...
    }

    @Override
    public void onError(UdooBluException runtimeException) {

    }
    }, 
    <PIN_NUMBER>
    );

6.2.2 Multiple pin Write digital pin

    udooBlu.digitalWrite(0, 1);    // HIGH
    udooBlu.digitalWrite(0, 0); 	  // LOW

Or if we call this method inside the UdooBluAppCompatActivity

    udooBlu.digitalWrite(0, HIGH);    // HIGH
    udooBlu.digitalWrite(0, LOW ); 	  // LOW

Or generic

    udooBlu.digitalWrite(0, IOPin.DIGITAL_VALUE.HIGH);    // HIGH
    udooBlu.digitalWrite(0, IOPin.DIGITAL_VALUE.LOW));   // LOW

Subscribe notifications 7.1 Digital read

 udooBlu.subscribeNotificationDigital(new INotificationListener<byte[]>() {
   @Override
   public void onNext(byte[] value) {
     boolean[] pins= UDOOBLESensor.IOPIN_DIGITAL.convertIOPinDigital(value, d1);
   }
 
   @Override
   public void onError(UdooBluException runtimeException) {
 
   }
 });

7.2 Analog Read

      udooBlu.subscribeNotificationDigital(new INotificationListener<byte[]>() {
        @Override
        public void onNext(byte[] value) {
          boolean[] pins= UDOOBLESensor.IOPIN_ANALOG.convertADC(value);
        }
      
        @Override
        public void onError(UdooBluException runtimeException) {
      
        }
      });

UDOO BRICK sensor

 udooBlu.subscribeNotificationTemperature(new INotificationListener<byte[]>() {
         @Override
         public void onNext(byte[] value) {
             float temp = UDOOBLESensor.TEMPERATURE.convertTemp(value);
         }

         @Override
         public void onError(UdooBluException runtimeException) {

         }
     }, 2000);
