Is this library ESP32-S3-DevKitC-1-N8R8 compatible

[vinothkrstatiq]

while compiling the board i got below error Arduino: 1.8.19 (Windows 10), Board: "ESP32S3 Dev Module, Disabled, QIO 80MHz, 8MB (64Mb), Core 1, Core 1, Hardware CDC and JTAG, Disabled, Disabled, Disabled, UART0 / Hardware CDC, Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi), 921600, None"

Error compiling for board ESP32S3 Dev Module.

This report would have more information with "Show verbose output during compilation" option enabled in File -> Preferences.

Hi @vinothkrstatiq

Thank you for the report. The compiler output shows that the library versions are not compatible with each other. Does it also print error messages if you compile a blank sketch with only arduinoWebSockets? What if you specify the same version numbers as in the platformio.ini?

I see that the ESP32-S3 support has just been released (https://github.com/espressif/arduino-esp32/issues/5594). I will also do checks for my library and notify you if I can reproduce this error.

Btw. if it's just the filesystem library then you can continue the development for now by deactivating the flash functionality. The build flag AO_DEACTIVATE_FLASH removes all references to the filesystem API.

I'm closing this assuming it's no longer relevant.
