/* The true ESP32 chip ID is essentially its MAC address.
|
||
|
|
This sketch provides an alternate chip ID that matches
|
||
|
|
the output of the ESP.getChipId() function on ESP8266
|
||
|
|
(i.e. a 32-bit integer matching the last 3 bytes of
|
||
|
|
the MAC address. This is less unique than the
|
||
|
|
MAC address chip ID, but is helpful when you need
|
||
|
|
an identifier that can be no more than a 32-bit integer
|
||
|
|
(like for switch...case).
