This might be a out of league question and may seems to be very odd.I am using multiple Arduino UNO boards over network and want to assign a GUID and Serial number to each board so that when ever they send any data to a central server, server is able to find which Device it is if we have assign name for each device.
- first way to do this is to assign GUID and serial number of device before each message that is send to central server manually while programming and then burn that hex to arduino.
Now is there any way out that we can burn a program that always give a output as a string (GUID+Serial number of device) like we program EEPROM for this and then burn our main code in Arduino which pick the GUID+Serial ID combo from EEPROM and write it before every message which arduino is pushing to central server.
Or my another way of asking is can we program EEPROM with a different program and our Arduino separately like 2 files running in parallel or is it not possible?
Is there any other way of doing this?
