Cannot find Bluetooth Printer on Android

[DorianLovera]

Hello and thank you for your work on this plugin so far.

I am currently facing a critical issue with the Bluetooth on this plugin. After calling findNetworkPrinters() or findBluetoothPrinters(), the method returns an empty array : [ ]

What I have tested so far:

• I have tested discovery through Wifi and it works well by returning the Printer's interface.

• I tried to hardcode the Bluetooth interface using the Printer's mac adress but the setPrinter() method returns the following: An error occurred while trying to set the printer.

Configuration

Printer : QL-820NWB Mobile Phone : Google Pixel 1 - Android 10 Framework : Ionic 4

I really hope that someone can help me resolve this issue. Can this be linked to a depreceated SDK or a missing authorization for Bluetooth in my config.xml ?

Thank you for your support

I have discovered the following commented lines in the plugin config.xml :

<uses-permission android:name="android.permission.BLUETOOTH" android:required="false" /> <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" android:required="false" />

I will try to uncomment them tomorrow at work, test and keep you updated.
