Can I ask you why you don't provide the log in the format needed? EVERYWHERE you can find a note how to provide the log in the correct format.

Anyway. Python is case sensitive and you have a typo in your BLUETOOTH_BMS config setting. You wrote JKbms_Ble instead of Jkbms_Ble. The second letter has to be lowercase.

Sorry for log format. Anyway. I make a mistake with these JKbms_Ble like you wrote.

Thank you for your help, now its working.
