My attempt is to know how to identify the board I'll be sending parameters to in a serial connection like rs485. I'm asking because I will have about 11 or so mcu's as "Rx slaves" while my pc is the Master "Tx". I want to know how my code block is being sent to a specific board will be received by just that board and not all the other boards connected to that Rx port COM?
If I send 'LT2|LP3|LM5|LR4|LI6' and I want that to be for one specific Arduino, I don't want all the other 10 arduinos to take those parameters in this serial Rx line.
@Federico Fissore you mentioned in another post "Some boards, when connected to a computer, publish their serial number. My Arduino Uno R3 says"
[16818.451423] usb 3-2: SerialNumber: 85235353137351E02242
how and where can i find this info?
