 <p>ESP32 hardware equips only one RF circuitry for WiFi signal. At the AP_STA mode, ESP32 as an AP attempts connect to another AP on another channel while keeping the connection with the station then the channel switching will occur causes the station may be disconnected. But it may not be just a matter of channel switching causes ESP8266 has the same constraints too. It may be a problem with AutoConnect or the arduino core or SDK issue. This problem will persist until a specific solution.</p>

 <p>The saved SSID would be cleared by  <em>WiFi.disconnect()</em> with WIFI_STA mode. If you do not want automatic reconnection, you can erase the memorized SSID with the following simple sketch.</p>
