Someone had experience with this ?
It seems that this one don't have unique MAC so writing random will be good ?
The shield must be assigned a MAC address and a fixed IP address using the Ethernet.begin() function. A MAC address is a globally unique identifier for a particular device. Current Ethernet shields come with a sticker indicating the MAC address you should use with them. For older shields without a dedicated MAC address, inventing a random one should work, but don't use the same one for multiple boards.
Yes, inventing a random mac address should work fine!
Onions.
Do you know how to convert the MAC that is given to us on the board to the proper byte array that the software is looking for?
This one is good for generating random MAC
But I have no idea how to convert it ...
New questions appears -
I find that you can connect breakboard using corssed cable to LAN socekt in computer, same cable can be used to connect it to router
If someone needs library I found one
Do you know how to convert the MAC that is given to us on the board to the proper byte array that the software is looking for?
The string on the sticker looks like:
11-22-33-44-55-66
The mac address array looks like:
byte macAddr[] = {0x11, 0x22, 0x33, 0x44, 0x55, 0x66};
