  • bleak version: 0.22.2
  • Python version: 3.11.3
  • Operating System: Windows 10
  • BlueZ version (bluetoothctl -v) in case of Linux:

Description

Bleak works fine the first time after Booting windows. Buf after one successfull operation I cant get the same programm to run. Either the connection cannot be established or it wasnt properly closed the first time.

import logging
from bleak import BleakClient

logging.basicConfig(level=logging.DEBUG)

address = "0D:8C:DC:22:11:11"
async def connect():
    async with BleakClient(address, timeout=30.0) as client:
        services = await client.get_services()
        print(services)

import asyncio
asyncio.run(connect())

After first execution the status toggles between active and closed

Error: <BluetoothError.SUCCESS: 0>, status: <GattSessionStatus.ACTIVE: 1>
error: <BluetoothError.SUCCESS: 0>, status: <GattSessionStatus.CLOSED: 0>

and failes at the end

ile "C:\Users\ladmin\AppData\Local\Programs\Python\Python311\Lib\site-packages\bleak\backends\winrt\client.py", line 168, 
in _ensure_success
    raise BleakError(f"{fail_msg}: Unreachable")
bleak.exc.BleakError: Could not get GATT services: Unreachable

A reboot fixes the problem and gives another try. .... but this is really annoying...

Does anybody has an idea?

Sounds like a bad Windows Bluetooth driver. You could try logging Bluetooth packets to see what is going on. See troubleshooting page in the docs for instructions.

FYI, you can put them in a .zip file and upload them. But I think we can see enough info from the pasted log.

There is no reply from this request, so it looks like you have a defective Bluetooth peripheral.

You might be able to avoid this by trying the use_cached_services=False argument. See https://bleak.readthedocs.io/en/latest/backends/windows.html#bleak.backends.winrt.client.WinRTClientArgs.use_cached_services.

Thanks,
whats odd is that it seems to work with other computer pretty well and everytime I reboot the machine its working as well. Passing the option used cached services to False unfortunally didnt solve the issue.

You could do a packet capture of the working cases and compare them to the not working cases to see what the difference is.

This started happening for me recently on Linux.

Bleak: 0.22.2
Python: 3.12.4
OS: Fedora 40
bluetoothctl: 5.77

The version of bleak I have installed was through pip. This may have been due to me switching from NixOS to Fedora. The version of bleak I had on NixOS was installed via some nix magic, whereas the version of bleak I have installed now was just the one available on pip. I don't recall if this ever worked correctly on Fedora / with pip version.

This is the error that prints the second time I try to run my program after a successful first run:

Rebooting my computer is the only thing that has worked so far to let me run my program again :/
