Not impossible to see a list of MACID's in use.

Some devices cloning is allowed etc...

Read up some more on this it is not as spooky as it seems plus you can jot it down and change it back or to whatever as needed.

Take care and enjoy.

- Sat Nov 14, 2015 5:26 pm #34001 BTW, each ESP has 2 MAC addresses, one for AP mode and one for STA mode.
For example :

Code: Select allSTA = 18:FE:34:xx:xx:xx
AP  = 1A:FE:34:xx:xx:xx


Those 3 first bytes are really assigned to Espressif ESPs, the 3 last ones are unique for each ESP leaving the factory.
Of course, there is a function in the SDK to set new MAC addresses, but there is no needs to use it, except to have clones.
