There is in my repository I didn't made a PR because i had to do some break changes in the connection methods, but you can use in my github to check if it's enough for you

Hi! Thanks for flutter_epson_epos and your bluetooth extension. Any chance you can create a PR and merge it with the main project? That would be very helpful! Thank you!

If @mrtungdev allows me, i can fork again his version and put in his version.

@brasizza I am facing an issue with the Bluetooth functionality, whenever I press on Discovery Bluetooth I get an error saying the following:
E/onDiscoveryPrinter( 7178): Start not working onDiscovery W/System.err( 7178): com.epson.epos2.Epos2Exception W/System.err( 7178): at com.epson.epos2.discovery.Discovery.start(Discovery.java:220) W/System.err( 7178): at com.tlt.epson_epos.EpsonEposPlugin.onDiscoveryPrinter(EpsonEposPlugin.kt:223) W/System.err( 7178): at com.tlt.epson_epos.EpsonEposPlugin.onDiscovery(EpsonEposPlugin.kt:199) W/System.err( 7178): at com.tlt.epson_epos.EpsonEposPlugin.access$onDiscovery(EpsonEposPlugin.kt:62) W/System.err( 7178): at com.tlt.epson_epos.EpsonEposPlugin$MethodRunner.run(EpsonEposPlugin.kt:129) W/System.err( 7178): at java.lang.Thread.run(Thread.java:1012)

Please any help would be highly appreciated, I not really familiar with Kotlin.

i think he didnt implement that featute, the 199 is the exception "not implemented"

you can try to use my fork that is bluetooth implemented to test!

@brasizza I was using your repository :) But it turned out it was a mistake from my end, the application requires Nearby Location permission which is not visible in the settings until you start the application and start searching for the printer via Bluetooth. For anyone facing this issue, please do the following:

1. Start the example application.
2. Click on search by Bluetooth
3. If it doesn't work, go to the app settings from your phone and enable all 3 permissions ( Location, Nearby Devices & Storage ).
4. Try again.

This is what worked for me. I am not sure if storage permission is required but I enabled it just incase.

The phone I am using is Oneplus 7T Pro.

Again, @brasizza thank you for your work. It is much appreciated.
