CAN bus data read with MCP2515 on CANhacker terminal via Arduino IDE and ESP8266 Car or battery BMS  Code link- https://github.com/gsrathore97/CANHackerProject Video link- https://www.youtube.com/watch?v=rWEZJeNOWSg There is two configuration 1- BMS and Microcontroller are already communicating with each other in the manufacturer's system In this case we can only read from this system using Arduino(broadcast type). 2- BMS is there with CAN system In this case we have to send CAN request frame commands to get the data on Arduino only.(Command and listen)
