The field kit
on your phone.

Connect a sensor, choose its radios, and start a scan. WLAN Commander brings network observations, client activity, packet capture, and Passpoint discovery into one app.

Live Wi-Fi capture uses an external sensor. Your phone provides the interface; available tools depend on the hardware you connect.

03 / First scan

From image to observations.

  1. Prepare a sensor

    Write the matching Linux image to its storage, or flash ESP32-C5 firmware over USB. Each sensor page has its own setup instructions.

  2. Connect in the app

    Put your Linux sensor on a reachable network and connect with SSH, or discover your ESP32-C5 over Bluetooth LE.

  3. Choose channels and scan

    Select the sensor and radio, choose the scan channels, and start. The app displays observations as they arrive.
