what is the best way to setup seeing all the traffic going to the emulator? I want to connect an ELM327 to the emulator, send some commands and see how the traffic is being formatted. I also want to do this with my ESP32 connecting to the emulator via a CAN Shield

You can use a CAN bus sniffer or monitoring tool, like Wireshark with a CAN interface, to capture and analyze the traffic between the ELM327 or ESP32 with the emulator.

Use a library like ELMo to simplify communication between the ELM327 and your ESP32. This library allows you to send commands and receive responses synchronously bitlife

You can reverse-engineer the format or protocol being used between your devices and the emulator, particularly if you're sending standard commands through the ELM327 or ESP32.

ELM327 Logging: Many ELM327 software tools (such as Torque, ScanMaster, or RealTerm) allow you to Drive Mad log and inspect the raw CAN or OBD-II data. You can enable debug mode to see how commands are formatted and responded to.

ESP32 with CAN Shield: If your ESP32 is connected via a CAN Shield, you can use an open-source CAN bus sniffer like candleLight, SavvyCAN, or BUSMASTER to capture the traffic. With an MCP2515 module, you can configure your ESP32 to log and print out all CAN messages in real-time.
