Remove pybluez as it is no longer supported and causes installation errors on modern Python versions.
Update ws_handler to use websocket.request.path (websockets 14+ change) with a fallback for older versions. Refactor main to use asyncio.run() and async with websockets.serve() to fix 'RuntimeError: no running event loop'.
…PU usage - Add asyncio.sleep(0.01) to prevent 100% CPU usage. - Remove sys.exit() and catch exceptions in Session.handle to prevent server crashes. - Fix _get_dev_uuids to collect all advertised UUIDs (fixes LPF2 Hub discovery). - Allow empty filters in discovery to match all devices. - Improve discover logic to reset scan state on failure/empty results, enabling retries. - Use withResponse=True for BLE writes to improve reliability with LPF2/WeDo hubs. - Robustify error handling in connect and _cache_characteristics.

I downloaded and tested this version on Ubuntu 24.04.3 LTS with a WEDO 2.0. It seems that it works as expected. |

Hi, thanks for building this project, i found it very useful.
I'm using scratch web app with a chinese clone of Lego Wedo 2.0, and found two issues trying to use pyscrlink.
With the help of a LLM agent i was able to get it working for me. I don't have enough experience with Bluetooth to evaluate if all the changes are need or the best options, but i reviewed the changes and seems good to me.
If you don't have the time to maintain the project, don't hesitate and just leave a short comment and i will publish my own fork.
Again, thanks for this project.
