Hello Sir, I need your help, I have one issue with my BMS. When I compile your code after including #include it is also add in my manage library. It shows the error 'Serial1' was not declared in this scope. and I noticed here you are used printf function in Arduino. I want to connect my Daly BMS with the ESP8266 for getting the data from BMS. I tried getting the data from BMS using Python code also. can you explain how should I have to connect my esp8266 with Daly BMS using UART I used three-pin the first 1 is GND 5th is TX and 6th for Rx? Is it okay? and please provide a code for getting all data from BMS. please help me, sir. I request you.

Can you show your wiring diagram of Daly BMS with arduino please

I think the issue you're running into is that the Arduino Uno only has one UART peripheral. This means that you can either communicate with a laptop via UART over USB or the BMS via UART. You might want to look at using a teensy (that's what I used, this code hasn't been tested on an arduino yet) or possibly move to an arduino variant that has multiple UART peripherals, like an arduino Mega. See this chart for arduino models & their UART peripherals:

The ESP82xx have only one full UART Serial port the Serial, the serial1 is only a tx on D4 for debuging. so you need to change it to Daly_BMS_UART bms(Serial)
