It determines how the two devices communicate with each other after the connection is established. In this example, this provides a BLE APP activity (DeviceControlActivity) is connected to the display data, the display device supports GATT services and characteristics.BLE: Android built-in platform to discover devices, request and transmit information from our bluetooth device.

The app gets data from the GATT server, which is a BLE heart rate monitor that supports the Heart Rate Profile. But you could alternatively design your Android app to play the GATT server role. See BluetoothGattServer for more information. Sep 05, 2014 · A Simple GATT Server, Part 2. If you bought the breakout board linked in the previous post from Jeff Rowberg, congrats! It is already pre-flashed with the gatt.xml, hardware.xml and everything you’ll need to get it work immediately with the Arduino sketch to follow. If you didn’t, refer to this to learn how to flash your BLE112. In this page you can find the example usage for android.bluetooth BluetoothGatt requestMtu. Prototype public boolean requestMtu(int mtu) Source Link Document Request an MTU size used for a given connection. Usage. From source file:org.physical_web.physicalweb.BluetoothSite.java GATT Server. The RxBleServer interface provides the functionality of Android's BluetoothGattServer. It's capable of providing and advertising services as well as connecting and disconnecting clients. To get an instance of the default implementation, use the ServerBuilder: BluetoothGattServer server=bluetoothManager.openGattServer (context, bluetoothGattServerCallback); BluetoothGattService service = new BluetoothGattService (SERVICE_UUID, BluetoothGattService.SERVICE_TYPE_PRIMARY); This is an example of a BluetoothGattCharacteristic with full write,read and notify permissions. According to your needs, you might want to fine tune the permissions that you grant this characteristic: For example you could implement the onCharacteristicReadRequest(...) method to return data to a device reading the characteristic on your BluetoothGattServer. I seem to have an issue since adding the server with the gatt client connecting however, I am assuming the problem occurs when the...For example you could implement the onCharacteristicReadRequest(...) method to return data to a device reading the characteristic on your BluetoothGattServer.
