The main feature of the esp32 chip, as it was for its predecessor esp8266, is for sure the ability to connect to wifi networks. I’ve already blogged in a previous article about the different standards (802.11 b/g/n) and security methods (WEP, WPA-PSK…) the chip supports; today I’m going to explain how to develop a program…

Thanks to a small usb->wifi adapter you can transform the Raspberry in a wireless access point that broadcasts a wireless network your device…
