# V2X2MAP

> V2X2MAP lets anyone receive and map live ITS-G5 / V2X road traffic radio (5.9 GHz, IEEE 802.11p)
> using a ~$20 Waveshare ESP32-C5 board as receiver and a phone app: Android (Google Play, free)
> or native iOS (TestFlight beta, App Store release at EUR 1.99). Messages are decoded on the
> phone (CAM, DENM, SPATEM, MAPEM, IVIM), no cloud required.

Key facts:
- Hardware required: Waveshare ESP32-C5 dev board with the open-source V2X2MAP firmware; without it the map stays empty.
- Android connects via USB-OTG or Bluetooth LE and can flash the board itself; iOS connects via Bluetooth LE only, the board is flashed once with the free macOS flasher tool.
- The apps show vehicles (with speed, turn signals, braking), roadside units, hazard warnings (DENM) as notifications, traffic-light phases (SPATEM), statistics, recording/replay (.pcap) and offline maps.
- Optional MQTT forwarding to OpenTrafficMap (off by default). Receiving radio services may be regulated in your country.
