cannot connect again unless reboot
- 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.
Hi,
yes it can be the driver. I checked for updates but there is non available...
i did already but couldnt upload pcap files here.

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 :/
This started happening for me recently on Linux.
This issue is about Windows, not Linux. So please start a new issue for the Linux issue and include a full reproducible test case.
