The ESP32-C5 datasheet doesn't mention support for 802.11p. Could you tell us how you implemented 802.11p packet capture using the C5? Did you contact Espressif to obtain a PHY library that supports it?

    The creators of the OpenTrafficMap project said in their talk that they found it via (legal) reverse engineering.

    Here are the slides (PDF; page 17) and the talk at the Grazer Linuxtage (both in German and also linked from the official Wiki of the project).
