Are you implementing an IoT system that requires you to identify many connected devices? This post reviews different types of IDs and provides some technical details to help you decide if any of these are appropriate for your application.
Are you considering implementing a web UI in your Zephyr RTOS application and perplexed by the endless number of web technologies available today? This article traces my journey through trying several options and presents some of the tradeoffs.
Modern microcontrollers (MCUs) have many connectivity options (Ethernet, WiFi, Bluetooth, Cellular, etc.), and when coupled with the Zephyr OS, implementing a web application on these devices often makes sense. Once you start doing this, you soon realize that this is not Ruby-on-Rails. Rather, Zephyr is still a very constrained environment (see my article on the differences between MPUs and MCUs). While we can still leverage modern web technologies, we need to be selective because of the constraints of MCU systems. An example of a web UI in the Zephyr SimpleIoT project is shown below:
