📱Bonus: Capture using WLAN Pi and iPhone or iPad

Airtool Pi is an excellent iOS utility that allows remote frame capture using an iPhone or iPad. It is available for purchase on the Apple Store. It can automatically discover a WLAN Pi on the same network as the iOS device and initiate an over-the-air capture on the WLAN Pi.

Airtool Pi can communicate with your WLAN Pi over various connection methods, including:

• Bluetooth

• Wi-Fi

• iOS OTG

Note: Not all WLAN Pi models support OTG, including the WLAN Pi M4.

Airtool Pi saves the capture as a PCAP file that you can share via AirDrop, iCloud, Dropbox, etc., and open with Wireshark on another device (e.g., your Mac).

Here are a few screenshots that demonstrate how to use Airtool Pi:

Home Page

From the initial page presented by Airtool Pi, it's possible to configure the app and view and configure the sensors that the app will use.

During the first use of the app, you will also be prompted to select auto-discovery of WLAN Pi sensors that may be found on the same network as your iOS device.

Sensors

Clicking on the Sensors option will display the WLAN Pi sensors that have been added to Airtool Pi. It also provides the opportunity to add more sensors using the "+" control:

When adding a new sensor, you may enter the link-local address wlanpi-xxx.local or IP address into the Hostname field:

Perform Capture

To start a capture, select a sensor from the list and use the channel selection controls to select the band, channel, and channel width for the frame capture (note that 6 GHz captures are supported!):

Once selections have been made, hit the capture button. The capture will now begin and a screen showing the capture progress will appear:

The capture may be terminated at any time using the "Stop" button.

Once the capture is completed, a new entry is generated with details about the capture. You may share the capture via AirDrop, e-mail, iCloud, Dropbox, etc. for analysis using Wireshark.

Note: There is no lab as such for Airtool Pi.
