(Win11) Random error messages on every execution

[shortcakesweets]

• bleak version: 0.22.3
• Python version: 3.8.10
• Operating System: Win11 22631.4602
• BlueZ version (bluetoothctl -v) in case of Linux: No Linux Required

Description

I'm trying to connect a remote controller to PC. The remote uses 'Just Connected' protocol.
I've built the project using python venv.
Bleak gives random error messages each time I execute it.
(It's strange because I've used bleak with no problem on this very same environment, but one day it stopped working)

Libraries I'm using on venv (checked with pip list):

async-timeout     4.0.3
bleak             0.22.3
bleak-winrt       1.2.0
pip               24.3.1
setuptools        56.0.0
typing_extensions 4.12.2

What I Did

I used this code;

import asyncio
import os
from bleak import BleakClient

address = "D0:1B:1F:82:11:23"

async def reproA():
    async with BleakClient(address) as client:
        print("Connected. Pairing...")
        await client.pair()
        print("Paired.")

if __name__ == '__main__':
    # clear previous logs
    os.system('cls' if os.name == 'nt' else 'clear')
    asyncio.run(reproA())

Sounds like it could be a not well-behaving Bluetooth adapter. Perhaps Intel integrated wireless/bluetooth?

You can see what is going on better at a low level by logging Bluetooth packets with Wireshark as described in the troubleshooting page of the docs.

[shortcakesweets]

Hi, I've got the packet log using Wireshark.
I don't think the reason is from bluetooth malfunctioning. I've tested with several peripherals and server pairs, and all seems to fail.

The log is from the environment above

• bleak version: 0.22.3
• Python version: 3.8.10
• Operating System: Win11 22631.4602

Meanwhile, I've found that using python 3.12 (where the dependencies are not bleak-winrt, but uses several packages) makes consistent error message. I'll try to log that in advance.

[dlech]

I see a potential problem:

There is no response from the peripheral for this Read By Type Request. There should either be a Read By Type Response or an Error Response.

It looks like the Bluetooth driver gives up after waiting 1/2 of a second for the response.

[shortcakesweets]

If that's the case, I don't understand why directly connecting to the same computer-peripheral pair works properly but using bleak doesn't.

also sorry for closing and reopening; my mistake

[shortcakesweets]

Also if somebody sees this issue with Windows11 working environment, please give me

• python version
• used libraries (using pip list)
• minimal working code example

This would help a lot 👍
