Gluon Mobile : Bluetooth Low Energy no instance for interface com.gluonhq.attach.ble.BleService - javafx

Question

I am new on stackoverflow, this is my first post. I recently started using Gluon Mobile to develop an android mobile application using Bluetooth Low Energy.
I'm having trouble using the BLE technology. If I copy the piece of code provided in the gluon mobile documentation and I get the following message :
WARNING: No new instance for interface com.gluonhq.attach.ble.BleService and class com.gluonhq.attach.ble.impl.AndroidBleService
here is the code from the example:
ble.startScanningDevices().addListener((ListChangeListener.Change<? extends BleDevice> c) -> {
while (c.next()) {
if (c.wasAdded()) {
for (BleDevice device : c.getAddedSubList()) {
System.out.println("Device found: " + device.getName());
device.stateProperty().addListener((obs, ov, nv) -> {
if (State.STATE_CONNECTED == nv) {
System.out.println("Device connected: " + device.getName());
}
});
ble.connect(device);
}
}
}
});
});
I also modified the AndroidManifest.xml file to provide the necessary permissions to use the bluetooth by adding the following lines to the file :
<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
Have any of you encountered this kind of problem and managed to solve it? I feel like I can't access the bluetooth.
here is a copy of the pom.xml file :

Answer 1

The solution was to add <list>ble</list> to the <attachList> in pom.xml file.
