Unique Identifier #2860
-
|
My project requires a unique identifier for every device, but not all of them have WiFi or Bluetooth where I can get a MAC address from. Would it be possible to get some kind of unique identifier for the device? Possibly a CPU serial number or similar? I am using LoRa (not LoRaWAN) with the SX1262 module, which doesn't have any unique identifier as far as I can tell. Any ideas are appreciated :) |
