What is it?

Raspberry Pi Compute Module 4 (CM4) is the brains of a raspberry pi 4 but without any of the IO ports, instead we start with a 'carrier board' possessing the desired IO ports and we add a CM4 to it.

The board we are testing with the WLAN Pi CE is manufactured by 'Mcuzone', can be purchased from AliExpress here, the solution is still to be validated. We don't recommend ordering one just yet.

Parts

• Sandisk Edge or similar 32 GB or larger micro SD card - From $10.99

• Raspberry Pi Compute Module 4 (we recommend one with built-in Wi-Fi, so we can use the bluetooth module)

• Mediatek MT7921K or MT7922 (Wi-Fi 6E module)

• antennas

• Waveshare screen and buttons

• GPIO riser

We have identified two Mcuzone carrier boards of interest!

Mcuzone CM4_wifi6_PoE Expansion board

$76 + $12 (shipping) Total $88 USD

Pros

• PoE power input

• Type-C power (limited, see below)

• 40-pin GPIO (requires pin header) for display connection

• Bluetooth works on MediaTek adapters (USB bus is internally connected to M.2 slot)

• Slightly smaller than the WLAN Pi Pro carrier board

Cons

• No OTG - you can't establish data connection between your laptop and the board via USB

• No Real Time Clock (RTC)

• Potentially limited type-C options, varied results in testing regarding power from Macbook Type-C to Type-C or PD charger

• Only one M.2 slot for Wi-Fi adapters

Power over Ethernet (PoE)

The M4 has built-in PoE circuitry. No additional power supply is required. This is the recommended option.

USB-C port of your laptop

WLAN Pi M4 can also be powered by USB-C port of your laptop using USB-C to USB-C cable.

Some older laptops might not be able to provide enough power via USB. Please double-check.

Apple USB-C PD MacBook chargers

While some MacBook USC-C chargers will charge the M4, some won't.

Power Distribution (PD) charger

A standard 5V USB-C PD charger is the best option.

Warning

Please do NOT use non-PD power supplies with USB-C connector, that are not rated at 5V. Doing so will result in a magic smoke escape. We've tested that, so that you don't have to.

The WLAN Pi hotspot mode has been created to provide a quick and dirty wireless AP for tasks such as wall attenuation measurements. It will also allow a temporary wireless connection when you'd like to hook up to a switch ethernet port and extend the network connection out to a wireless client. Finally, it can be used to provide wireless access to the WLAN Pi itself if an OTG or Ethernet connection is not available.

Visit the article below to get the full details on Hotspot code:

"Classic" mode is the default mode that WLAN Pi boots into with a fresh OS install. It is the mode that is most likely used for 90% of the use-cases that you will have for the WLAN Pi.

The WLAN Pi may be switched in to a number of "modes" that change the primary operating characteristics of the device. This is generally required to change the fundamental networking characteristics of the WLAN Pi Pi to provide a specialized feature that would otherwise clash with the networking setup required for standard, day-to-day operation.

When the WLAN Pi is powered on, the home screen show on the front panel provides useful status information about the unit. If the home screen displays the title "WLAN Pi Pro", then your unit is in Classic mode. When switched to other modes, the current mode is displayed as a title on the home screen.

To switch to other modes, use the menu system on the WLAN Pi. Use the navigation buttons to select the required mode from the "Modes" menu item. Note that the WLAN Pi will reboot when switching between modes.

The other mode available are:

- Server Mode: a lab network server to provide miscellaneous useful functions

- Hotspot Mode: a simple wireless access point

- Wi-Fi Console: a wireless CLI console

The WLAN Pi server mode enables use cases like lab build, software upgrade of your network appliances or AP and staging with no additional servers or apps. Simply plug your WLAN Pi into your lab switch and let it provide all services.

Airtool can perform 'local' and remote Wi-Fi packet captures using a capable Linux box with a compatible Wi-Fi adapter such as... the WLAN Pi. Airtool 2 makes it possible to perform affordable, multi-channel captures using multiple remote sensors and Wi-Fi adapters.

Download and install Airtool 2

Launch Airtool

1. Verify Airtool is running in your menu bar (Wi-Fi icon with a wrench spanner

2. Configure Airtool 2 Preferences

Airtool dropdown > Preferences

Capture using a remote sensor

Remote captures are achieved using SSH to connect to the remote device. When Airtool 2 connects to the device using SSH, it remotely executes a series of commands to capture Wi-Fi traffic. These commands drop the device's Wi-Fi adapter (e.g., wlan0) into monitor mode, set the desired channel and channel width, and then runs tcpdump to capture and send the Wi-Fi frames back over to Airtool 2 via the SSH connection.

Because Airtool 2 will use the remote device's main Wi-Fi adapter for capturing, Airtool 2 needs to connect to the device using a wired connection or a secondary Wi-Fi adapter.

If you were to do this using a secondary Wi-Fi adapter, ensure the channel you will be capturing is not the same as the Wi-Fi adapter being used for device access.

All Airtool 2 features (automatic frame slicing, capture size limits, file rotation, live captures, etc.) are available when capturing using a remote sensor in the same way as when capturing using the built-in Wi-Fi adapter.

Using a sensor

To use a remote sensor, go to Preferences > Sensors and add a new sensor. You will need the hostname or IP address of the sensor. If the sensor is not configured to use the standard SSH port (TCP port 22), then you need to specify the correct port number in the Port field. Then, choose the sensor from the Airtool 2 menu to start the remote capture.

Before the capture starts, you will be prompted to enter the name of the wireless interface you wish to capture on remotely (e.g., wlan0) and to select the channel and the channel width.

The first time you capture from the remote sensor, you will be prompted to authenticate using the remote device's SSH username and password. You can choose to have Airtool 2 remember the credentials, so you don't have to enter them every time you do a capture. Airtool 2 will store the credentials securely in your Mac's keychain.

Managing sensors

To manage the sensors, go to Preferences > Sensors. You can add, edit or delete existing sensors, mark sensors as favourite, and change the sensors' order by dragging the entries in the list.

More details: https://www.intuitibits.com/help/airtool2/#/topic-capture-remote_capture

Capture on multiple channels and remote sensors

You can also use Airtool 2 to capture Wi-Fi traffic on multiple channels simultaneously by using multiple remote sensors or a single remote sensor with multiple Wi-Fi modules. Airtool 2 generates a single capture file by merging the frames captured on each sensor based on their timestamps.

To ensure the correct merging of Wi-Fi frames from each sensor, Airtool 2 requires all sensors to synchronize their time using NTP.

Airtool 2 uses the PCAP Next Generation (pcapng) Capture File Format. This format allows Airtool 2 to annotate each frame with the sensor and interface name used to capture the frame. You can use this information to filter frames by sensor and interface name in Wireshark.

You can also capture Wi-Fi traffic on multiple channels simultaneously using the same remote sensor if the remote sensor supports more than one Wi-Fi adapter. For example, if you have three remote sensors, and each sensor supports two Wi-Fi adapters, you can capture Wi-Fi traffic on six different channels simultaneously.

Advanced Airtool 2 features, such as automatic frame slicing and live captures using Wireshark, are also available for multi-source captures.

Prepare for a multi-source capture

You must first go to Preferences > Sensors and add any remote sensors you would like to use for multi-source captures. You only need to add a remote sensor the first time you use it. After that, the remote sensor will always be available for multi-source captures.

Airtool 2 discovers WLAN Pi-based remote sensors deployed in your local area network automatically.

Also, make sure you plug in at least one compatible Wi-Fi adapter per remote sensor and know the interface name assigned to it (e.g., wlan0) as you will need it when configuring the remote sensor for capturing.

Start a multi-source capture

1. Choose Multi-Source Capture from the Airtool 2 menu.

2. Click the "+" button to add an entry for each remote sensor you want to use for capturing.

3. For each entry, configure which sensor, interface name, channel, and channel width you want to use.

4. Click "Start Capture."

Airtool 2 won't allow you to start the capture if it detects an invalid configuration. For example, you cannot use the same sensor and interface name combination twice.

To reduce the amount of data sent back from a remote sensor, you can choose to limit each captured frame's size by enabling the "Limit each frame to" option and entering the desired frame size in bytes.

It can be annoying to have to sit in an equipment room to use the serial console port on an item of networking equipment. This module allows you to use a WLAN Pi to connect to your serial console cable via a Wi-Fi link while sat in the comfort of a nearby office, rather than sat with your laptop on the equipment room floor :)
