Two different boards with same IP number

Hi …


Arduino UNO | Arduino Mega 2560
Auth Token “A” | Auth Token “B”
Project “A” | Project “B”
Blynk Account “A” | Blynk Account “B”
Same network

Each project, called alone, works perfectly but when I turn the two boards on the same network, both receive the same IP number. With that, the two projects are unstable.

How can I fix this?

Thanks a lot

Please ensure that both boards have different MAC addresses… then they will get diferrent ip and should work.

I’m sorry but how can I do this setting?

There are some Ethernet examples. They also contain information to set the MAC.

Dear Lichtsignaal
I found the examples.
It took me a while to understand the “philosophy” of how to apply the example in my project.
