ZeroTrace HID
WiFi Connectivity
What the WiFi radio is used for now that control runs over Bluetooth
ZeroTrace HID is controlled from the mobile app over Bluetooth, not over WiFi, and the device no longer hosts a browser web UI. The WiFi radio is still on board, but its job now is internal: it powers the TraceNetwork mesh and fleet WiFi scanning. Configure WiFi from the app under Settings.
AP mode
The device runs its own WPA2 access point, which underpins TraceNetwork (the ESP-NOW mesh pins to channel 1).
| Setting | Default |
|---|---|
| SSID | [DeviceName] ZT |
| Password | ZeroTrace |
| Channel | 1 (when TraceNetwork is on) |
The SSID and password are configurable in the app, see WiFi SSID for disguising the AP name.
Fleet WiFi scanning
The radio can scan surrounding WiFi networks and, across a TraceNetwork fleet, aggregate results from every agent for full RF coverage of a site.
Disabling WiFi
Disable WiFi entirely from the app's Settings for engagements that prohibit RF emissions. The device falls back to USB-HID plus BLE only, BLE is still how you control it, so the mobile app keeps working with WiFi off. (TraceNetwork and WiFi scanning are unavailable while WiFi is off.)
Hardware
WiFi is integrated into the ESP32-S3. There is no external antenna or dongle. Range is bounded by the on-board PCB antenna.
