By any chance is there some device serialization number that is stored in NVR3 or NVR4 at manufacturing? It would be nice to have a unique per-device number that could be used by the firmware as a serial number or private key for various purposes.
I guess that the NVR3 BLE Address or NV4 MFG BLE Address could be used, assuming these are all unique per device. Is that true? And what is the difference between the NVR3 and NVR4 BLE Addresses?
Any other solutions to having a unique ID per RSL10?
