simple 3-object switch, so why is it resetting HTML?
Posted: Tue Apr 30, 2019 9:31 amHopefully, this hasn't been posted before, But...
the simple direct Wifi <---> NodeMCU (in AP Mode) single object switch, but adding 2 more connections/LED's, (a simple Common-Anode tri-color LED as the base setup right now.). now if I strip-out the extra 2 objects/LED's, it works fine, but the full code, all attempts to call-up the html page, are refused (web page reset)...
the code:
So, what is going wrong here? is the code too big for the NodeMCU to handle all at once? should I be splitting it into lua files , or, is there a incorrect piece of the code? be gentle, still a newbie at this.
