Bluetooth and ionic : device not detected


I have.a problem with ionic and bluetooth. I need to create an Android Bluetooth server (API 19 only …) and an ionic client (for Android & IOS).
My iPhone detect my Bluetooth server and can pair with it but my ionic apps doesn’t see it.

I am new to the Bluetooth World and I am a bit lost :confused:

My Android server :

mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
tmp = mBluetoothAdapter.listenUsingRfcommWithServiceRecord("MyAPP", MY_UUID_SECURE);

When I start this code on my Android Phone, my iPhone see it in the Bluetooth menu and I can pair with it (both Phones request to validate a code).

When I launch my ionic app on my iPhone, the Android server is not found. I only see 4 results : my MacOS computer and 3 results without name … If I stop the bluetooth on my Computer, all results disappear. :confused:

import { BleClient } from '@capacitor-community/bluetooth-le';

try {
      await BleClient.initialize();

      await BleClient.requestLEScan(
        (result) => {
          console.log('BLUE received new scan result', result);

      setTimeout(async () => {
        await BleClient.stopLEScan();
        console.log('BLUE stopped scanning');
      }, 20000);  
    } catch (error) {

There is something I do not understand, someone can help you please ?

Thank you,

The @capacitor-community/bluetooth-le plugin only supports Bluetooth Low Energy (BLE). Your Android code looks like a Bluetooth Classic server.
