ESP32 iBeacon Advertising

There’s recent example code for the M5StickC, usable on almost any ESP32 device, that shows how to advertise iBeacon. The nice thing about this example is that it also shows the iBeacon parameters on the OLED display.

While adding iBeacon advertising to an ESP32 project can make sense, it’s often not the best choice if you only want advertising functionality. Stand alone beacons are more physically robust, use much less power and settings are configurable via ready-made apps rather than fixed in code.
