📱Bonus: iOS Setup

Airtool Pi is a great iOS utility that allows remote frame capture using a iPhone or iPad. It's available for purchase on the Apple Store. It can automatically discover a WLAN Pi on the same network as 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 models of WLAN Pi support OTG (e.g. WLAN Pi M4 does not).

Once frames have been captured, they are saved as a PCAP files that can be shared via Airdrop, Dropbox etc. to be opened with Wireshark on another device.

Here are a 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 you 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 6GHz capture is supported!):

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

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

Once the capture is completed, the PCAP file may be found in the "Airtool Pi" folder of the iPad and shared to another device via Airdrop, Dropbox etc. for frame decoding using Wireshark.

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