Identity must be equal to the username: ***@***.*** As far as I remember, since there’s a bug in the sdk you can only use ***@***.*** as username and identity. Otherwise everything’s going to be overwritten by this specific hard-coded credential. Moreover on the Openssl configuration (server side) you need to force the server to accept TLS 1.0 connections.

If you’re using Arduino IDE, simply select the ESP-12E board and all the libraries will be loaded accordingly. Il giorno sab 25 feb 2023 alle 01:04 bhamicus42 ***@***.***> ha scritto:

***@***.**** commented on this gist. ------------------------------ Where can I find the library(ies?) that define WiFi.h, esp_wpa2.h, and esp_wifi.h?
