How to get UID/MAC number?

terefere

I will use DC80480PW in my product, probably without wifi. I need to delete from my slave device eeprom who have MAC number and wonder to know... maybe Dacai screen can give me this number?. If they have wifi, then I suppose that yes. But how about screen without wifi, they have also some unique ID?

You can use this api to get the mac address of the screen, the details are in the link below

Hmm, with this function I get error "attemp to call a nil value". Works 'get_wifi_mac()'.  but is little bad because I need to order screen with wifi module who I no need.
Or I made something wrong?
