In the latest update to Sungres and Moongres, users can now use their smartphone as a mobile station to track the position of the Sun and Moon and create their own devices.
The smartphone calculates all the necessary data about the Sun and Moon and transmits it via Bluetooth (BLE) to microcontrollers such as ESP32, Arduino, STM32, and other boards. Developers can immediately use the ready-made data in their projects, such as trackers, automatic positioning systems, solar panels, or any other devices that require information about the position of the Sun and Moon.
Documentation for the mobile station and an implementation example for ESP32 are available at this link.
