Модель была спроектирована по размерам, указанным в инструкции. Спасибо за прошивку, но есть другая проблема. ПК не подключается к BMS. Пробовал rs 485 также через UART, результат отрицательный. Выдает такие ошибки! кстати подскажите пожалуйста стабильную версию программы которая будет корректно работать v2.7 на виндовс 7 часть информации размыта

Если найду, обязательно поделюсь
Не ви у мене в ютубі питали про підключення ? Кілька тижнів тому.
На рс485 пару з даними а/б перекидали?
Скоріше за все я! Так перекидав нічого не змінилося. UART теж намагається передати пакет файлів але безуспішно!

I use this RS485 cabel (from aliexpress) and it works perfect. You should plug it in the rs485 port next to the can-port (not one of the two 485-ports that are intended to parallel batterys

Calibration
if you have different voltages on battery and on BMS. And currents too

Is it possible to connect this BMS to Solar Assistant with the new firmware?
Could you please show me the pin-out for RJ45? I already have the converter, but I can't find a pinout for the rs485 port
Or send me in a private message a link for this cable
---UPDATE---
I found

I also have two packs - I use two cables (each BMS is connected with its own cable to an USB-Port on the PC) and switch the COM-Port and Master / Slave in the software. I think there is no communication "PC - slave battery" when connected to the master battery (over the RS485-connection between the two cells).
I'm trying to create DIY monitoring with esphome, but I can't receive any response from BMS.
I'm using the UART protocol and commands from the original doc.
Maybe somebody has a positive experience with that or knows some helpful project, it would be great.

Translation: Hello, does anyone have a user manual and settings for the BMS, there are some entries that cannot be translated into English
Take a look at https://github.com/smaksimowicz/esphome-jbd-bms

Here are the docs I collected regarding JBD SW and Hardware - maybe you can find the info you are looking for ...
I checked with my BMS, but it doesn't work, unfortunately
Debugging looks like this https://monosnap.com/file/Slgrr3uWLeiwBPd7ZImzWUypOfxzUG
I'm using MAX485 UART-RS485 converter and ESP32 (also checked with Wemos d1 esp8266)
This converter works correctly for reading telemetries from the Deye Inverter.
p.s. On PC it works with bms tools application v2.7 only, not with higher version or else bms tools (converter RS485 with CP2102).

From logs it seams that BMS is not responding for proper command. I'm using UART TTL to RS485 CIA00485T module. I'm powering this module with 3.3V direcly from esp32 board. Plase check also dip swith configuration - you have to set them all to 0 according to logs.I checked with my BMS, but it doesn't work, unfortunately

Also check your esp32 uart connections - they must be conected straight rx(esp)->rx(rs485 module) tx(exp)->tx(rs485 module)

Got it, thanks.
I think that my problem is related to flow control, and I should use
Code:
flow_control_pinAnyway, I ordered the same converter with auto-flow direction control.
--- UPDATE ---
Yeah, it works with a flow control pin. It's weird why the original author decided to skip this option
very thanks for the git link @arH1983

Hello guys!
I have 2 items these BMS and I want connect parallel.
I have issue with parallel connection.
There was connected 2 BMS RS485(Parallel port) - RS485(Parallel port), for slave BMS i put address (1000).
I can't connect to slave BMS via master BMS from PC.
And LCD dispay wrote in menu PackPara->"This content is not settable"
Can you share diagram how to configure parallel connection?
