- ESP32 – Developing With ESP-IDFOkay things have gotten a bit more complicated than we are used to. Since the arrival of the ESP32 module, Espressif the maker of the ESP modules has also worked hard behind the scenes. They have developed IDF. IDF is the compiler for all ESP32 XX chips. So for HomeKit Development, we have to start … Read more
- ESP32 – Auto Program & ResetThe upload procedure for ESP32 boards is a little different from a standard Arduino procedure. Most Arduino’s will automatically reset when a new program is being uploaded, and will automatically enter programming mode. On some ESP boards you have to manually enter programming mode, and on the bare-bones modules, you even have to reset them … Read more
- ESP32 – Capacitive touchIn this blog, we will discuss how to use the ESP32 touch sensors and how to use the esp32 touch sensors as a push button without having to connect an external push button. The ESP32 chip offers ten touch sensors. These touch sensors are built-in with ESP32 chip and are capacitive type. These touch sensors … Read more
- ESP32 – HomeKit LEDAfter writing quite a few blogs about ESP8266 in combination with HomeKit SDK, it is now time to look at the ESP32. The ESP32 and actually the ESP32-C3 is the upcoming replacement for the ESP8266. That’s why I’m going to show you how to migrate from the ESP8266 to the ESP32 series. We start simply … Read more

HomeKit Accessory Protocol (HAP) is Apple’s proprietary protocol that enables third-party accessories in the home (e.g., lights, thermostats and door locks) and Apple products to communicate with each other. HAP supports two transports, IP and Bluetooth LE. The information provided in the HomeKit Accessory Protocol Specification (Non-Commercial Version) describes how to implement HAP in an accessory that you create for non-commercial use and that will not be distributed or sold.
The HomeKit Accessory Protocol Specification (Non-Commercial Version) can be downloaded from the HomeKit Apple Developer page.
