Error handling is kind of rough in that script, agreed, but won't fix (error handling) as I switched to cable-serial-USB connection in my setup.

For this specific issue - there seems to be a communication issue between py-script (it doesn't get any response -> timeout), bluetooth (somewhere, I'm no expert here) and/or daly bms-system.

I have no daly bms in use anymore and did not follow their firmware updates (if any, which might trigger the need for changes here).

So, sorry, won't fix, as this is more a "proof of concept" for my personal setup. Feel free to fork and continue to develop.
