my config file is:

• address: C8:47:8C:E5:AB:CB
  type: jk
  alias: JK-B2A24S20P

im not sure if thats right, but what i have in alias is what shows up on the jk app or bluetooth discovery. the mac address is correct.

im not 100% sure i have mqqt setup correctly, as their didnt seem to be anywhere to create in a username and password? - do i even need one?

any help appriciated thanks :-)

then it becomes undiscoverable and i have to switch the bms off and on again to see it via bluetooth...

Hi, rpi 3b+..

Hi,
I am experiencing some difficulties connecting to JK BMS as well on my RPI 3B+
I disabled build in Bluetooth and connected TP-Link Bluetooth dongle. I managed to successfully connect Daly BMS to my HA using Batmon addon, but when I am trying to establish a connection to JK BMS JK-B2A8S20P I see errors

INFO [sampling.py:67] connected bms JKBt(C8:47:8C:EC:76:D1)!

Do you have any suggestions on how it can be fixed?
Thanks

Ive sorted the mqtt stuff, should be ok, but still getting the same problem in the log..?
