bluetooth-low-energy-applications VS ZSWatch

If you need some more background, I wrote a book, Develop your own Bluetooth Low Energy Applications for Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr, and you can find all code examples in its GitHub repository.

If you want some more background about BLE development, I've written a book with a practical approach: Develop your own Bluetooth Low Energy Applications for Raspberry Pi, ESP32 and nRF52 with Python, Arduino and Zephyr. This also includes a chapter about how to read BLE specifications such as the Health Thermometer Service and create code to support the specification. All code examples from the book are freely available.

Here's an example of a Zephyr application that sends indications for BME280 sensor data in a custom BLE service: https://github.com/koenvervloesem/bluetooth-low-energy-applications/blob/main/4-connections/zephyr/peripheral_bme280/src/main.c

Been working on this a few months now. It's my first "real" PCB. I'm very happy with the result and is already working on a new revision with new more powerful MCU and touch screen. If you want the look into it in more details I publish the files including PCB and FW here https://github.com/jakkra/ZSWatch

Hi, sure, you can find it here https://github.com/jakkra/ZSWatch under app/drivers/display
