Captive portal is not triggered on IOS #35

Closed reneklootwijk closed 3 years ago

reneklootwijk commented 3 years ago

On my iPhone running IOS version 14.3 the captive portal is not triggered. When I connect to the AP the first time I have to explicitly go to 192.168.100.1 in a browser to get to the config screen. I tried other frameworks, e.g. AutoConnect, and there the captive portal is automatically triggered.

Try without setting a static IP for the AP I.e remove ESPAsync_wifiManager.setAPStaticIPConfig(...) This solved the issue for me and the captive portal now triggers on the default 192.168.4.1

Thanks for helping here. You're absolutely correct.

The iPhone (or a WebBrowser on any device) will auto-redirect to the Captive Portal IP 192.168.4.1, which is a default AP IP set by ESP (private-code) cores. Currently, the only way Captive Portal is auto-triggered and opened is to use that 192.168.4.1 AP IP. Otherwise, you have to manually open the CP.
