ESP8266 wemos d1 mini web server
Posted: Fri Feb 01, 2019 10:33 pmHi, I am dealing with a problem in my project based on wemos d1 mini clone module, issue is web server stops responding randomly and specifically when I try to access http://1.1.1.1:88/update, for the first time page come up with update option but when using http://1.1.1.1/ and after toggling some switches and/or try to access http://1.1.1.1:88/update it hangs (ping from wemos ip is ok), then the only way out is to reset wemos. Experts are requested to please shed some light on issue, thanks in advance.
here is the sketch:
