 /**
- * @brief Task to perform WiFi scanning asynchronously.
+ * @brief Asynchronous WiFi scanning task for ESP32 with FreeRTOS.
  *
- * Starts a WiFi scan, polls for scan completion,
- * retrieves and logs the found access points, then deletes itself.
+ * Configures and initiates a non-blocking WiFi scan on the specified or all
+ * channels, including hidden networks if enabled. Periodically polls for scan
+ * completion without blocking other tasks, retrieves discovered access points
+ * up to a defined maximum, and logs each AP's SSID and signal strength (RSSI).
  *
- * @param pvParameter Task parameter (unused).
+ * After logging, the task self-deletes to free system resources.
+ *
+ * This design ensures WiFi scanning runs in the background, preserving system
+ * responsiveness and maintaining real-time operation in embedded applications.
+ *
+ * @param pvParameter Pointer to task parameters (unused).
