How to get started with the ESP32

Derive unique device identifier from hardware

I want to add some noteworthy thing about the ESP32:

The ESP32 has a unique hardware wifi MAC address. It would be useful to use this MAC as the basis for a self-generated Dev-EUI. We are doing a similar thing with Raspberry Pi base LoRaWAN gateway - take the ethernet MAC, split it in half, and add FFFF or FFFE in the middle. The result is a valid self-assigned EUI.

Gibt es die nicht auch schon bei den ESP8266? Werden die IDs bei nicht auch so generiert?
