Wireless diagnostics.
Multiple ways to connect.

KeshAutoDiag supports wireless OBD-II adapters over Bluetooth LE and Wi-Fi, with USB passthrough via the Windows connector. The hardware abstraction layer means adding new adapter support without changing your workflow.

  • 📡
    Bluetooth LE — Low-energy BLE adapters for mobile use
  • 📶
    Wi-Fi — ELM327-compatible Wi-Fi adapters
  • 🔌
    USB (Windows) — Direct USB connection via Windows connector
  • 🔬
    Simulated — Development and testing without hardware

Research-first approach

Adapter compatibility is verified before implementation. Generic OBD-II support does not guarantee access to every manufacturer-specific ECU.
