Release Notes & Known Issues ESP32 Firmware 1.2 & 1.2.1
- The ESP32 board can now act as an http server for the SVG files. You have to copy the SVG file to the flash card in the root directory. Then the app can load the file from there. Syntax: http://<board-ip>/file/<svg-name>.svg, Beispiel: http://192.168.178.65/file/myfile.svg
- Bugfix in version 1.2.1 – It often happened that the data was not saved on the SD card.
Release Notes & Known Issues ESP32 Firmware 1.1
- The oled display switched off after a configurable time. It turns on when a magnet is held over the ESP32 chip. As a result, the display is less stressed and it does not age so quickly, which is clearly visible on my board. It is also possible to configure the brightness.
