How to explain this Google Chrome and ESP-01 trick?
Posted: Tue Jul 31, 2018 4:29 am
I run web server on ESP-01 to control GPIO (input/output). To show you this Chrome trick I've attached LED to see visually what is surprising me. To turn ON LED we need just enter to this URL: http://192.168.57.164/gpio/0 , to turn off - URL: http://192.168.57.164/gpio/1 that is we can control LED sending HTTP GET requests.
Like you see in my video it’s enough to correct from 0 to 1 and BEFORE pressing Enter on the keyboard LED change his state. Web sniffer on the left shows that after URL edit we have GET request before it submitting. This behavior is on Chrome browser only and I can’t reproduce the same with Chrome and any other website
