ESP32 web server; works in STA mode -but- not AP mode

Postby campinLOU » Sat Jan 28, 2023 2:48 am

Problem: uploaded web server created by Jason Coon via esp32-fastled-webserver; works as described in Station Mode; added softAP mode to existing code; Station mode still works without any problems -however- softAP will not connect and load web pages even though WiFi channel is created. Changed channel from default "1" to "9" with no change in working status; changed IP address with same results; changed from using Arduino 1.8.19 to VS Code, same results

This looks like the 3rd web server problem in a row, and I have the same suggestion:

before you spend more time on this I suggest to use the ASYNC server:
https://github.com/me-no-dev/ESPAsyncWebServer
A bit steeper hurdle to start, but at some point you will need it anyway!
