BMS Barcode reading in lltjbd.py / add changes to dbus-serialbatttery driver

[JigneshMali]

Hello, I have been working on this little part of the project where I want to read the barcode of the lltjbd.py BMS and replace the product ID with the barcode number in cerbo GX GUI (battery --> battery Details --> product id = barcode read) . I tried to change it by following how the device name is being read and shown in GUI passing through all relevant files. but then installing the updated driver to Cerbo. but Cerbo does not recognize BMS at the port. I need support in this.

I am adding the relevant zip files.
