Yesterday, I wrote about the OpenTrafficMap ESP32-C5 C-ITS receiver board to monitor and potentially optimize traffic using 802.11p / ITS-G5 V2X communication over 5.9 GHz WiFi 6, and map all detected nodes on the OpenTrafficMap website. Peter Holzhauser (Pit711) forked the ESP32-C5 C-ITS receiver firmware to port it to the Waveshare ESP32-C5-WIFI6-KIT development board and added BLE streaming. He also designed the V2X2MAP open-source Android app to interface with the board (since 5GHz WiFi on phones can’t usually handle 802.11p), and a Windows installer to flash the firmware. While the ESP32-C5 C-ITS receiver board integrates an ESP32-C5-WROOM-1 module, a GPS module, and an Ethernet port with PoE, the V2X2MAP project leverages any recent Android smartphone with a USB OTG port and GPS, so you can simply connect most ESP32-C5 boards to monitor live traffic at proximity (a few hundred meters to several kilometers) on your phone including traffic lights, public […]
