MovisensGattLib

MovisensGattLib is a Java library that simplifies the work with movisens Bluetooth SMART sensors (a.k.a. Bluetooth Low Energy in Bluetooth 4.0). It provides all UUIDs of the movisens sensors and an convenient way to interpret the characteristics (e.g. MovementAcceleration, RMSS).

This library is build on the SmartGattLib. Please read the documentation there as well.

There is also a complete example project on how to connect to the movisens Sensors.

Set up

1. Add the JitPack repository and the dependency to your build file:

  repositories {
      maven { url "https://jitpack.io" }
  }
  dependencies {
      compile 'com.github.movisens:SmartGattLib:3.6.0'
      compile 'com.github.movisens:MovisensGattLib:2.15.0'
  }

or download the latest .jar file from the MovsiensGattLib releases and the SmartGattLib releases and place it in your Android app’s libs/ folder. 2. Use the example below to identifiy services and characteristics and interpret their data

    }else if (MovisensCharacteristics.SAVE_ENERGY.equals(characteristicUuid)) {
        // TODO: Write enable to characteristic MovisensCharacteristic.characteristic to go into energy saving mode
    }
}else{
	System.out.println("Found unused Service: " + MovisensServices.lookup(serviceUuid, "unknown"));
}


// onCharacteristicChanged
UUID uuid = null; // TODO: Fill with the received uuid
byte[] data = null; // TODO: Fill with the received bytes

AbstractAttribute a = Characteristics.lookup(uuid).createAttribute(data);
if (a instanceof MovementAcceleration) {
    MovementAcceleration movementAcceleration = ((MovementAcceleration) a);
    System.out.println("Received MovementAcceleration: " + movementAcceleration.getMovementAcceleration());
}
