Connect your ESP32 sniffer
Plug it in with a USB cable, press Connect USB and choose its port. Frames appear here as the car talks. Works in Google Chrome on a computer.
No device at hand? Press Simulator above to try the page with made-up frames. Phone or tablet without a cable: a Wi-Fi version is in testing; it needs a sniffer with the Wi-Fi firmware, which is not part of the standard firmware package yet.
Counters since the board started. Buffer peak is the fullest the board's receive buffer has been; any overflow means frames were lost on the board. Loss on the USB link to the computer is not counted here.
Capture a baseline, then press a button or open a door in the car. The IDs and bits that changed show up here.
