	Sniffing between OBD and Diag Tester « on: April 22, 2024, 03:39:08 PM »

Hallo i tryed all to find out how to sniff the traffic between the OBD and the Diag Tester. Y - Cable i allready have.

I tryed ELM327 Terminal... AT Z, AT SP 4, AT HC1, AT MA - dont work. AT MA dont show me anything. I Use a ELM327 clone. Maybe that is the Problem ?

Wireshark + ESP32 i dont get to work.

Look at Savvy Can. They even provide an esp32 firmware. Use an A0 or an A0 clone esp32 to flash it and log with savvy.
