[peterthepower]

Hi,

I have 3 MiniTeyleten Robot D1 Mini ESP32 ESP-WROOM-32 and none of them want to connect to my wifi network.
I try many code but nothing work
IF I try the wifi manager in esp32, I can connect with my iphone esp and setup wifi connection but never connect to my wifi.

If anyone can help
thank you very much
have nice day
