8.9.6. Searching for Characteristic
You can search for the Characteristics on a connected BLE device by executing the callback
function setGattCallback() and Characteristic search using discChar().
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
//
Set StartHandle and EndHandle from the Service information
//
acquired in
onDiscPriSrvResult
mManager.discChar (ConnectedHandle, StartHandle, EndHandle);
}
Use the following callback to output logs when a Characteristic is detected.
private BluetoothLeGattCallback mLeGattCallback =
new BluetoothLeGattCallback() {
@Override
public void onDiscCharResult(char connectedHandle,
};
};
}
