Good day all,
I'm running a script on my RPi Zero 2 W using Bullseye 64-bit OS using a long range bluetooth adapter (LM1010). Been running for a year now without too many issue. The script simply connects to a couple of my BT adapters in my backyard shed solar panel system, and dumps the data on my MQTT broker (for Home Assistant).
The script can be found
here
It uses python-dbus.
However, yesterday, I ran just your normal system updates 'sudo apt-get update then upgrade', now when I try to run the script, I get these errors.
Code:
INFO: Adapter status - Powered: True
INFO: Starting discovery...
Traceback (most recent call last):
File "/home/pi/.local/lib/python3.9/site-packages/gatt/gatt_linux.py", line 156, in stop_discovery

reply_message = self.send_message_with_reply_and_block(

During handling of the above exception, another exception occurred:

raise _error_from_dbus_error(e)
gatt.errors.Failed: Method "StopDiscovery" with signature "" on interface "org.bluez.Adapter1" doesn't exist
and eventually, after many attempts to try the start the script, the error message turns to this:

I'm kind of stuck and regret updating (if that was what cause the issue).
I completely wiped my RPi and started from scratch, and installed all the libraries again in the requirements file, but same problem exists.
Any idea how to solve such a problem?
thank you
