Python and Bluetooth Low Energy: Is there an alternative to pygatt?

Question

I'm trying to communicate with an ESP32 microcontroller and my linux desktop using Bluetooth Low Energy.

Right now I'm using the notification example from https://pypi.org/project/pygatt/ (carefully replacing the MAC address and UUID of course).

The pygatt library runs gatttool under the hood, and is pretty flaky. Sometimes the example reports a single value before the program terminates. Sometimes it reports a spate of values and then hangs.

I was wondering if there were any alternatives to pygatt that were more robust?

gatttool is one of the eight tools that BlueZ deprecated.

BlueZ publishes an API using D-Bus and there are various D-Bus bindings for Python

For a BLE client you will need the following API parts of BlueZ:

An example of how to do this with pydbus is at: https://stackoverflow.com/a/63751113/7721752

There are also a number of other BLE Python libraries available on PyPI but not all of them built using the BlueZ supported D-Bus API.
