I’m trying to implement AsyncIO with Kivy.

I have MainWidget(BoxLayout) class which possesses all functionality of the code for our case it is communicating with Android API to fetch I/O network data e.g., scanning for unpaired Bluetooth devices. Please don’t ask why it is done inside MainWidget and not our App Class – wasn’t my doing.

class MainWidgetr(BoxLayout):
   async def scan_bluetooth(self):
         # [...] bluetooth logic here
         # how do I get this to run asynchronously when button is pressed?

Then, we have ClassApp(App) which consists of the function to run the app asynchronously. This is my first time working with asyncIO and I heard that it is a modern approach than Threading and if-not perfect for I/O bound problems though I also just want to test this vs Threading later.

Inside our ClassApp(App) class we have a app_func function as per Kivy AsyncIO advanced example.

def app_func(self):
    async def run_wrapper():
         await self.async_run(async_lib='asyncio')
    return asyncio.gather(run_wrapper())

Issue is, I tried looking on the internet on how to; when I press button Start Scan I want asynchronously carry out the scan. However, how do I go about adding it into the app_func or the Event Loop so that on button trigger the function is done asynchronously?

NOTE: My understanding of asynchronous programming is very basic so I hope my explanation is enough.

Thanks.
