You can also flash esp32 with your own FW. Here is very simple test that is using UART to communicate k210 with esp32. esp32 is flashed with custom fw: https://github.com/chegewara/sipeed-maixduino-test-apps/tree/master/platformIO/freertos/uart-to-esp32...

Like i mentioned in other topic, its NINA. https://github.com/sipeed/Maixduino_esp32_fimware
