Mist AP SSID on/off with MicroController
The idea behind this device is to provide a portable tool that allows you to stop the radios of a Mist Access Point.To make it more relatable, let's consider a scenario: Imagine a school with Wi-Fi access for students. However, teachers are unhappy to see students scrolling through their phones during class time. It's time to take action. With this designed box, you can easily disable the access point with a single push of a button (instead of unplugging it or accessing the Mist portal).

How to Make a Raspberry Pi Pico Wi-Fi capable?
Raspberry Pi Pico is a microcontroller board designed by the Raspberry Pi Foundation. It features the RP2040 microcontroller chip, which contains two ARM Cortex-M0+ cores clocked at 133 MHz, 264KB of RAM, and 2MB of onboard Flash memory for code storage. The Pico also includes 26 GPIO pins, which can be used for a variety of purposes such as controlling sensors, motors, and other external devices. Additionally, the board supports various interfaces such as I2C, SPI, and UART, making it easy to connect to other devices. The Pico is a great option for hobbyists and professionals alike who are looking for a powerful, yet affordable microcontroller board.While this microcontroller is versatile and can be used in a variety of projects, it does not have a built-in Wi-Fi chip. As a result, users often choose the Raspberry Pi Pico W or ESP series instead.

Python – Auto Rename Cable Notes in Ekahau
Naming cable notes in Ekahau is quite a manual process. You have to enter your note description at the end of drawing the cable note on the map.What I like to do on my projects is rename the cable notes in the following way: "IDF-1 to AP01". We then re-use this description in our report to provide the information to both the customer and the installers.

Python – Auto-Populate Tag Values in Ekahau Pro
Ekahau released a new version (v10.2) last month. The best feature out of this new version (for me at least) is the ability to create personalized tags for AP objects. Each tag can have a key and a value.

Mist – API Call within a Python Script
In a first video, I explain everything you need to create your first API call to the Mist system dashboard. In order to make this API call, I use an application called Postman. Postman allows you to build your API calls in a very easy way. This is useful to test the API calls, make sure they work and analyze the results we get from the Mist dashboard.
