8.9.7. Searching for Characteristic Descriptor
You can search for the Characteristic Descriptor on a connected BLE device by
executing the callback function setGattCallback() and Characteristic Descriptor search using
discCharDesc().
import android.bluetooth.BluetoothLeAdapterManager;
import android.bluetooth.BluetoothLeGapEvtConnected;
import android.bluetooth.BluetoothLeGattCallback;
public class MainActivity extends Activity {
private BluetoothLeAdapterManager mManager;
@Override
protected void onCreate(Bundle savedInstanceState) {
Instance acquisition for the BLE manager class
//
mManager = BluetoothLeAdapterManager.getInstance();
Register a callback for the GATT function provided
//
mManager.setGattCallback(mLeGattCallback);
Searching for Characteristic Descriptor
//
//Set StartHandle and EndHandle from the acquired onDiscPriSrvResult
mManager.discCharDesc (ConnectedHandle, StartHandle, EndHandle);
}
Use the following callback to output logs when a Characteristic Descriptor is detected.
private BluetoothLeGattCallback mLeGattCallback =
new BluetoothLeGattCallback() {
@Override
public void onDiscCharDescResult (char connectedHandle,
int status, BluetoothLeGattChar[] data) {
};
};
}
