BMS JK-B2A20S20P connecting issue #189

Hello.

I got BMS JK-B2A20S20P (2A Balancing, up to 20 series, 200A) but cannot connect.

What I understood there are JK02 and JK04 protocols for Jikong BMS, where JK04 is not implemented fully here. First of all how to check does my BMS using JK02 or JK04 protocol?

Additional not sure about PIN because when I connect via application on smartphone then is need provide PIN 1st time. Please note I changed ping from default 1234 to 12345 - this is important?

Next question is regarding MAC address. [scanner] section in logs give me two MAC addresses but both not work, this mean I see lot's errors in py files in logs for both MAC.

General question is possible connect my BMS into batmon?

Model: JK-B2A20S20P
HW: V10.XG
SW: V10.07

Scanner provide 2 MAC addresses to me:
DC:23:4D:EB:B9:E4 TY
DC:23:4E:0A:8A:62 TY

BTW. Regarding logs - I cannot provide full log because is overwriting in batmon log tab and system -> logs -> batmon too even if I download full logs.

Paste log output between BEGIN and END for DC:23:4D:EB:B9:E4

hi,
enable install_newer_bleak to install bleak 0.20.2, which is more stable than the default version.

Thank you, is working fine now :)

BTW, maybe you now, what mean number "cell index max" and "cell index min" (without UoM)? Additional "num_cycles", "num_samples" both in UoM [N] and "total cycles meter" with value "0,0 N" ? General what mean UoM [N]?

PS. All energy [kWh] entities and one capacity [Ah] value display in wrong format but will create other issue for that (or keep here?). Coma is in wrong place.
