Below error appear when I create a task using xTaskCreate(vBLE_Notification_TaskCode, "NotiTask", 30000, NULL, tskIDLE_PRIORITY+2, &xBLE_Notification_Task);
C:/msys32/home/isp40/esp/esp-idf/components/freertos/queue.c:1442 (xQueueGenericReceive)- assert failed!
abort() was called at PC 0x400889f1 on core 0

I think vBLE_Notification_TaskCode() is very simple.

And menuconfig->Conponent config->ESP32 specific->main stack size is 16000.

Is the user stack larger than the main stack, causing an error?

The 'main' stack you refer to is literally nothing more than the stack allocated for the thread that runs the app_main function. All other tasks that get spin up get their own stack memory.

Thank you.

stack of the user's tasks is allocated on the main stack?
