Re: C++ error: Guru Meditation Error: Core 0 panic'ed (InstructionFetchError). Exception was unhandled
xTaskCreate(&task, "Test Task", 10000, NULL, 1, NULL); You have extra indirection that causes the code to crash. The call should be: xTaskCreate(task, "Test Task", 10000, NULL, 1, NULL); See the example in the docs: https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/system/fr...

Re: QT support for ESP32-S3
There appears to be a port of Qt for MCUs for the ESP-S3-BOX device: https://doc.qt.io/QtForMCUs-2.3/qtul-supported-platforms.html#other-target-boards . You need to contact the Qt company for access to the code and for setup instructions. Notice that Qt for MCUs is a small subset of the full Qt libr...

Re: NTP Update
Remove the setenv() and tzset() calls from timeSync() function, and place them in setup() before calling getLocalTime().

Try using esp_wifi_set_ps(WIFI_PS_NONE) to disable WiFi power saving mode.

Re: Sending struct information to the queue
Where is the array data_buf allocated? If it's a local variable to the sending function, it won't exist when the message is read and the space may have been overwritten by other data.

Re: how do I save variables into the nvs?
The maximum length of a NVS key is 15 characters: https://docs.espressif.com/projects/esp ... and-values, the key "user_msg1_length" you used is 16 characters.
Re: timer
The first comment line of the code states it's an example of the High Resolution Timer API and the documentation for esp_timer_delete() is on that page. No need to guess, just read more carefully.

Re: Ease of programming
No, you can't compile code for ESP32 with Visual Studio. You can edit code and launch the build system from Visual Studio Code, which is an entirely different program. See the ESP-IDF Programming Guide and example code for code structure. You can't use any Windows APIs. Some Unix/Linux type APIs lik...

Re: Missing fnmatch in ESP-IDF
Fnmatch() is defined in the Single Unix Specification (a.k.a POSIX), it's not part of the standard C I/O library. If your application requires complete Unix-style filesystem interface, perhaps a Raspberry Pi would be a more suitable platform than an ESP32.
