Prebuilt demos and examples

The package for Espressif ESP32-S3-BOX-3 board comes with a variety of prebuilt demo and example binaries, as well as a prebuilt bootloader binary. See the Flashing Instructions for Espressif boards and Bootloader flashing Instructions for Espressif boards topics on how to flash the binaries to the board.

Enabling DeviceLink

The reference port package comes with a Qt Quick Ultralite DeviceLink library, which is not enabled by default. Enable it by editing the platform_config.h file as follows:

1. Open <QT_INSTALL>/QtMCUs/2.12.0/platform/boards/espressif/esp32s3-box3-idf/platform_config.h in a text editor.
2. Uncomment the //#define QUL_PLATFORM_DEVICELINK_ENABLED line so that the config looks as follows:

   #ifndef QUL_PLATFORM_DEVICELINK_ENABLED
   // Enable the device link component.
   // For more details, see Qt for MCUs CMake manual QUL_PLATFORM_DEVICELINK_ENABLED page.
   #define QUL_PLATFORM_DEVICELINK_ENABLED
   #endif

After the change, the exported projects have DeviceLink enabled.
