Description

I'm trying to install bleak on a raspberry pi since it doesn't work on Ubuntu 22.04 #1333

What I Did

pi@pi1:~/Downloads/bleak $ pip install -e .
Directory '.' is not installable. File 'setup.py' not found.
pi@pi1:~/Downloads/bleak $ pip3 install -e .
Directory '.' is not installable. File 'setup.py' not found.
pip install bleak

No matching distribution found for dbus-next; platform_system == "Linux" (from bleak)

I suspect this might be because this is a 32-bit system?

Bah! I wanted bug #1337!

[dlech]

If you are not in a virtual environment, you need to use pip3 instead of pip so that it searches for Python 3 packages instead of Python 2.

Bah, the one of 4 options I didn't try! Yes pip3 install bleak worked.

Then it gives a similar, but slightly different, error to #1333:

We would need to see Bluetooth packet logs to be able to see what might be going on.

Have you tried on raspberry pi os bullseye? buster is quite old.

We're experiencing the same error, I've attached below the source code and some logs:
https://gist.github.com/iosifnicolae2/bc70134f317ce24234fa58740272fc4c

If you have any idea on how to fix this, thank you in advance :)

PS. The code works just fine on MacOS, but when running on Raspberry PI 3 A+, we're getting the bleak.exc.BleakDBusError: [org.bluez.Error.NotAvailable] br-connection-profile-unavailable error.
We're trying to connect to Bosch glm50c by adapting this code (https://github.com/ketan/Bosch-GLM50C-Rangefinder/blob/main/python/main.py).

Tomorrow, I would like to try to ignore this error.

PS. Also, when we try to connect to the BLE device from Raspberry PI interface, we're getting the same error.

bluetoothctl --version
bluetoothctl: 5.66
