2x JBD BMS, connected via bluetooth, not working as I expected

[apesfromspace]

Hi,

I have 2 JBD BMS with Bluetooth, installed in config.ini.
They work individually, but when both MACs are supplied on the BLUETOOTH_BMS line, nothing appears in Venus.

from /data/etc/dbus-serialbattery/reinstall-local.sh output:
Installing LltJbd_Ble 70:3E:97:EB:yy:yy as dbus-blebattery.0
Installing LltJbd_Ble 70:3E:97:EB:xx:xx as dbus-blebattery.1
Stopping bluetooth: bluetoothd.
Starting bluetooth: bluetoothd.

A bunch of errors in /data/log/dbus-blebattery.*/current

a snippit here: (I replaced the last 2 parts of the MAC with xx:xx for privacy, it is correct in the actual file)
