esp32 mqttHA.bin web not loading

[blackbrayn]

Hello, after succesfull upload to esp32 and initial ap wireless config, web interface does not load for setting the other parameters.
The esp device responds to ping but the console is full of reset messages, i have tried diferent 2.4 wireless networks/browsers.

Hello, in order enter to "configuration" mode and active the web interface you must put GPIO19 to HIGH (3.3v) and reset the esp, then you should be able to access and set the right values for your HA server.
WIFI credentials and all other settings are located in 2 different pages so you can't save them all at once, you need to set them in 2 times.
Then, disconnect GPIO19 from 3.3v (and use a pull down resistor just to be in the safe side), the esp will restart in the "normal" mode.

Esp will enter in "configuration mode" if it cannot connect to any wifi network (also), this is the reason why you was able to access to the web interface without any additional action.

Plase note that in "normal" mode, you don't have access to the web interface, if you need further adjustment on the settings you have to put GPIO19 high again and restart esp.

Thanks for the quick help, i managed to get it working. I used a 10k resistor to pull gpio19 high.
Just as a observation , if the mqtt user/pass is wrong there is no error message, it just hangs at "SETTING UP MQTT-HA", it would be nice for a future update to get a auth error or a generic one that tells the user to check the settings.

Good suggestion, I've opened an issue for that, I should check if and how mqtt/ha libraries permits to detect it.
