FAQ

How does discovery work?
Devices broadcast their identity every 30 seconds on UDP port 64321. The app listens automatically — no scanning needed.

Why can't I find my device?
Ensure your phone and the device are on the same WiFi network. Try the HTTP Scan feature with the correct IP range and password.

What devices are supported?
Any ESP32 device running PDD-compatible firmware: M501D Monitor, DC Controller, CAN Sniffer, and custom devices.

Is my data secure?
PDD works entirely on your local network. No cloud, no account, no data leaves your network. Secure discovery uses challenge-response authentication.

PRIVACY POLICY

PDD Scanner does not collect, store, or transmit any personal data. The app operates entirely on your local network. No analytics, no tracking, no cloud services. Device discovery data stays on your device.
