The following code is not fully tested.

static void stop_wifi(){

esp_wifi_disconnect();
esp_wifi_stop();
esp_wifi_deinit();

}

Thanks, but isnt that to disconnect the esp32 from an access point, not disconnect a station connected to the access point? I want to keep the wifi up on the esp32, just disconnect one of the connected stations

My application is a webRadio. It connects to an AP. I wanted to stop/remote WiFi completely which I think it is better to start fresh. I don't quite understand your applications and your definition of the term station.

A station is a device that connects to the esp32 access point on wifi.

Basically theres an issue with the esp32 that if a station connects to it when the wifi is coming up an IP is not assigned and left as 0.0.0.0, if theres 1 second delay and then connect, an ip is assigned.

I wanted to disconnect any station which hasnt been assigned a valid ip, so it will reconnect and be assigned a proper IP.

Just a way around the issue.....

Any other ideas would be appreciated or how to fix the issue !

Thanks

The logic I used for my application is reverse the process. If you have an event handler for each connection, then you should able to reverse the process disconnecting it.

Thank you for the reply, not sure what you mean by reversing the process, thought the event handler notified us of the wifi events?

How do I reverse this and disconnect the station ?

Thanks

It may be a call to esp_wifi_deauth_sta may be what we seek.
