just tried this on MicroPython 1.9.3 on esp8266 nodemcu board and it lets you connect but when you try to access 192.168.4.1 it runs out of memory.. loads on esp32 ok though.

I had a quick look at the code. Do you have a lot of ssids visible when this happens?

Then the datastructure with the wifi scan results and the html content list built from that will be rather big, maybe that is the problem (on very low RAM devices).

other wifi managers work with the same list of results.

what can be done to do this with your version?

same problem here on nodemcu (ESP12E). There are 6-9 available ssids around me. I tried to remove mqtt reference from my code to save memory but result is the same.

maybe we could emit the html piece by piece instead of assembling the whole body.
