Wifi mode Exception (28)
Posted: Thu Nov 16, 2017 3:58 pmHello 
I have problem with exception when changing Wifi.mode to station. First when ESP is turned on it setup itself as AP (setupWifi is first called in setup() ). Than i change settings on web configuration and save them on ESP, setupWifi is called again with accesspoint = false. Esp is than reset with Exception(28). Did a little of debug and it stops when WiFi.mode(STA) is called.
Code:
Code has Asyncserver running and when i trigger event from asyncserver it runs setupwifi again. Maybe setupWifi get's called multiple times? Because i tried create another script with async server and make it to change to station mode onclientdisconnect, and i get same problem.
Thanks for help!

Code has Asyncserver running and when i trigger event from asyncserver it runs setupwifi again. Maybe setupWifi get's called multiple times? Because i tried create another script with async server and make it to change to station mode onclientdisconnect, and i get same problem.
Code: Select all
void onEvent(AsyncWebSocket * server, AsyncWebSocketClient * client, AwsEventType type, void * arg, uint8_t *data, size_t len){
switch(type){
case WS_EVT_CONNECT:
Serial.print("Nov klient povezan ");
Serial.println(client->id());
break;
case WS_EVT_DISCONNECT:
accesspoint=false;
setupWifi();
break;
case WS_EVT_ERROR:
Serial.println("Napaka websocketa");
break;
}
}
Thanks for help!
