   * @brief     Set primary/secondary channel of ESP32
   *
-  * @attention 1. This is a special API for sniffer
-  * @attention 2. This API should be called after esp_wifi_start() and esp_wifi_set_promiscuous()
+  * @attention 1. This API should be called after esp_wifi_start()
+  * @attention 2. When ESP32 is in STA mode, this API should not be called when STA is scanning or connecting to an external AP
+  * @attention 3. When ESP32 is in softAP mode, this API should not be called when softAP has connected to external STAs
+  * @attention 4. When ESP32 is in STA+softAP mode, this API should not be called when in the scenarios described above  
   *
   * @param     primary  for HT20, primary is the channel number, for HT40, primary is the primary channel
   * @param     second   for HT20, second is ignored, for HT40, second is the second channel
