Description

from bleak import BleakClient
import asyncio
async def connect(addr,char):
    def notification_handler(_,r):
        print(r)
    async with BleakClient(addr,timeout=10) as client:
        await client.start_notify(char, notification_handler)
        await asyncio.sleep(3)
        await client.stop_notify(char)

while True:
    asyncio.run(connect(addr,char))
    if input(f'conitue')!='':
        break

When I first connect, I can receive notifications，But when I press ‘Enter‘ for the second run, I can't see any output.
I restarted the program, but there is still no message.
I switched to a visualization software and it's the same.
After restarting the Bluetooth device, i can receive messages without exiting the program.
I think it's my first time not really ending the connection, and I've been occupying it all along.
I don't know if this is a problem with bleak or my Bluetooth device
What should I do？
tks

update：

from bleak import BleakClient,BleakScanner
import asyncio
async def connect(addr,char):
    def notification_handler(_,r):
        print(r)
    async with BleakClient(addr,timeout=10) as client:
        await client.start_notify(char, notification_handler)
        await asyncio.sleep(3)
        await client.stop_notify(char)
async def scan():
    for i in await BleakScanner.discover():
        print(i)

    
async def main():
    await scan()
    await connect(addr,char)

asyncio.run(main())

I modified the code, and on the second attempt, "scan" can run but "connect" not run

asyncio.run() should only be used once per program. There is an aioconsole library that you can use to get input in a non-blocking way if you need to.

Thank you for your prompt response，That's the problem with my code.
For the aioconsole , I couldn't find sufficient documentation on Google. How should I rewrite it based on my functional requirements? Thank you
