The remote controller for the automatic antenna tuner ATU-100 is still under development. The last tests show that the most difficult part – to transfer the display data via bluetooth – is most probably possible as you can see on the video below. But as you can also see there is still lots to do and improve.
Also the picture below shows that it might work with some small improvements. The OLED display in the video and and on the pictures below shows the data captured on the tuner’s I2C BUS using ESP32 microcontroller which proccessed the data and transfer the data via bluetooth to another ESP32 microcontroller which receives the data and send them to the I2C BUS of an OLED display.
Anyway letš go back to work. And …. if there is someone capable to help with the development in the ESP-IDF let me know.
