ZeroTrace HID

WiFi Connectivity

AP mode, STA mode, and switching between them

ZeroTrace HID firmware supports two WiFi modes; switch in the web UI under Settings → WiFi.

AP mode (default)

The device runs its own WPA2 access point.

Channel1 (when TraceNetwork is on)

Use AP mode when:

  • You're working at the device, not a laptop already on a corporate LAN.
  • The target environment has no friendly WiFi to join.
  • You need TraceNetwork (which pins to channel 1).

STA mode

The device joins an existing WiFi network. Enter SSID and password in Settings → WiFi → STA. After connect, the web UI is reachable at the IP your DHCP server assigned (visible in the Companion app or on the device's OLED if it has one).

Use STA mode when:

  • You want to control the device from your normal laptop without joining a separate AP.
  • You need internet access for any OTA workflows.

Switching

You can run AP and STA simultaneously — the device acts as a bridge. Most operators run STA on their lab WiFi for editing scripts and AP for in-field deployment.

Hardware

WiFi is integrated into the ESP32-S3. There is no external antenna or dongle. Range is bounded by the on-board PCB antenna — typically 10–30 m through one wall.

Disable WiFi entirely under Settings → WiFi → Off for engagements that prohibit RF emissions. The device falls back to USB-HID + BLE only.
