Batman does not connect to jkbms #278

To start: thanks for your great work on the batman add-on!

I cannot seem to get it to connect to my batteries though... The scanner function does seem to pickup the bluetooth signal and I can connect to it with my phone a couple of metres further away from the BMS than my home assistant is located without any problems.

I'm not at all clear what the problem is. I've bought a bigger BT antenna and even moved the antenna closer to the BMS with a cable. Could somebody point me in the right direction?

These are the logs, i'm trying to read the items BMS Pack A and BMS Pack B:
