Fedora 39: [org.freedesktop.DBus.Error.NoReply] Remote peer disconnected #1471

vovagorodok · 2023-11-30T19:14:23Z

bleak version: 0.21.1
Python version: 3.12.0
Operating System: Fedora Linux 39
BlueZ version (bluetoothctl -v) in case of Linux: 5.70

Description

When script trying to read from peripheral characteristics, flowing error occurs:

[org.freedesktop.DBus.Error.NoReply] Remote peer disconnected

What I Did

Ble uploader trying to read information about device from characteristics.
Folowing script:
https://github.com/vovagorodok/ArduinoBleOTA/blob/main/tools/uploader.sh
executes uploader.py.

Works correctly when:

Used Ubuntu instead Fedora
Used bluezero instead bleak (by chenging to bluezero_uploader.py in uploader.sh)

Looks that issue is with bleak in Fedora 39 (trying in Lenovo T490 and HP Zbook 14u G6)

Please let me know what logs I should gather.
Thanks!

Used Ubuntu instead Fedora

Is everything else the same in this case? Same computer? Same Bluetooth adapter? Same BlueZ version?

Is everything else the same in this case? Same computer? Same Bluetooth adapter? Same BlueZ version?

Yes the same device (compuer and ble adapter). Before Fedora 39, Ubuntu 23.04 was installed, perhaps with older BlueZ version.
Checked in another computer with Fedora 39 and the issue exist.
Looks that issue is with bleak in Fedora 39.

As I see issue is in client._backend._acquire_mtu(). Acquire mtu is needed to achieve maximal upload speed.
Should I attach logs for export BLEAK_LOGGING=1?

File "/home/tsiselsk/Projects/private/ArduinoBleOTA/tools/uploader.py", line 83, in acquire_mtu
await client._backend._acquire_mtu()

I think this could be what is causing the problem. This looks like _acquire_mtu() is from a 3rd-party library. Whatever that function is doing could be triggering the disconnect.

Logging Bluetooth packets is useful too to see what is actually going on over the air.

Or do You mean wireshark logs?

dlech · 2023-12-04T00:19:56Z

Yes, I meant Wireshark.

vovagorodok · 2023-12-05T11:26:14Z

Captured wireshark logs:
bluetooth.zip

dlech · 2023-12-06T03:52:37Z

In the wireshark logs, it looks like it is starting to do some Bluetooth classic stuff after the Bluetooth low energy stuff. Is this a dual-mode device?

I'm not as familiar with those commands, so I don't know what it is supposed to look like, but I'm guessing BlueZ isn't getting an expected response or is getting a wrong response and disconnects.

dlech · 2023-12-06T03:54:40Z

If it works with one BlueZ version but not in another, I would report the bug to BlueZ.

vovagorodok · 2023-12-06T09:12:55Z

I also think it's probably a problem with BlueZ. Where issues with BlueZ should be reported?

dlech · 2023-12-06T14:41:54Z

Where issues with BlueZ should be reported?

https://github.com/bluez/bluez/ (or the Linux Bluetooth mailing list)

vovagorodok · 2024-02-11T23:52:34Z

bluez/bluez#670 (comment)
Looks that issue is somewhere between bleak and BlueZ just in latest Fedora 39 (in test Ubuntu 24.04 and same BlueZ ver works ok). Only dbus is between I gues?

vovagorodok · 2024-03-13T19:23:56Z

@dlech have You idea how to workaround issue for this moment? Because I'm without working solution in Fedora.
Trying:

and have logs like (exception that we already connected):

Connecting to ArduinoBleOTA
[org.freedesktop.DBus.Error.NoReply] Remote peer disconnected
Client is already connected

After removing reconnection I have exception:

[org.freedesktop.DBus.Error.UnknownObject] Method "ReadValue" with signature "a{sv}" on interface "org.bluez.GattCharacteristic1" doesn't exist

dlech · 2024-03-13T20:01:22Z

Issues with dual mode devices were discussed recently in #1521. I'm not sure what we can do about it besides fix it in BlueZ.

vovagorodok · 2024-03-14T00:08:33Z

In Ubuntu it works with the same BlueZ version. Created issue on Fedora side: https://bugzilla.redhat.com/show_bug.cgi?id=2269464
