PC disconnected but ESP8266 still in connected state

Projects Programming

I use ESP8266 in AP-Mode.
server.handleClient(); //update no of clients
MDNS.update();
byte Number_of_Client =wifi_softap_get_station_num();
stat_info = wifi_softap_get_station_info();
while (stat_info != NULL)
{
ip4_addr *stationAddress;
stationAddress = &stat_info->ip;
u32_t address = stationAddress->addr;
stat_info = STAILQ_NEXT(stat_info, next);
Serial.printf(" address : ");
Serial.printf("%d" , address);
Serial.println("");
}
wifi_softap_free_station_info();

When PC is connected, Number_of_Client is one.
Sometimes , PC automatically connects to another SSID.
However, Number_of_Client is still getting the value one.
Address is still the value before disconnected.
How to solve this problem?
Thanks a lot!

Welcome to the forum

Please follow the advice given in the link below when posting code, in particular the section entitled 'Posting code and common code problems'

Use code tags (the < CODE/ > icon above the compose window) to make it easier to read and copy for examination

https://forum.arduino.cc/t/how-to-get-the-best-out-of-this-forum

In my experience the easiest way to tidy up the code and add the code tags is as follows

Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help.
