So then, if the processing I want to do in response to the event is inappropriate for an ISR, I need to synchronize a task to the the ISR (with a queue, for example). And, I should also check if the task that wakes up has higher priority than the one originally interrupted by the WiFi Event ISR. If so, there should be a context switch. Upon receiving this event, the event task does nothing. The application event callback needs to call esp_wifi_scan_get_ap_num() and esp_wifi_scan_get_ap_records() to fetch the scanned AP list and trigger the Wi-Fi driver to free the internal memory which is allocated during the scan (do not forget to do this)!Refer to 'ESP32 Wi-Fi Scan' for a more detailed description.Interrupts In ESP32. ESP32 provides up to 32 interrupt slots for each core. Each interrupt has a certain priority level and can be classified into two types.
