ESP 32 Project
(1/1)
Farrel:
Hi, currently i'm in project that need indicator (sorta like LED) but in app (i'm using MIT App Inventor 2).

normally when the app communicate with the ESP, they use http:IP/command. But how does the ESP send data to the app and how to display it as an indicator (sorta like LED)?

Appreciate any help  :)

If you have implemented a web server in the ESP, data can be send through the IP/command chains. Lots of exemples on Internet.
