try to add a delay after changing the mode? worked for me once but not always, very strange

WiFi.mode(WIFI_AP_STA);
delay(1000);

Ok I think I have it now, let me play with it a bit

Sorry I keep forgetting this, So does esp give you a AP create failed error?

tablatronix on Jun 20, 2021

Yes, I also have the same problem. WiFi manager prevents creating an AP after configuring SSID Password with the portal. Need to restart the esp to resolve this. Any updates?

Hi I have deleted these two lines , but it still not work. res = wm.autoConnect("auto_test"); if(!res) { Serial.println("offline mode"); WiFi.mode(WIFI_AP_STA); // IPAddress apIP(192, 168, 10, 1); // WiFi.softAPConfig(apIP, apIP, IPAddress(255, 255, 255, 0)); WiFi.softAP("Offline"); }

and it works after I didn’t use wm.autoConnect:

res = false; //wm.autoConnect("auto_test"); if(!res) { Serial.println("offline mode"); WiFi.mode(WIFI_AP_STA); IPAddress apIP(192, 168, 10, 1); WiFi.softAPConfig(apIP, apIP, IPAddress(255, 255, 255, 0)); WiFi.softAP("Offline"); } So I believe that it is some code of wifiManger that affects create AP after autoConnect timeout, and I also check wifiManager source code and try ,but still not solved . Please help me, thanks a lot.
