Verify a unique identifier

[Timo]

Hello everyone,

I'm developing a security scheme in which the firmware verifies that the nRF51822 is the same as the one in the factory to which the firmware was installed, i.e. whether it's running on authentic hardware.

I'd like to know if the nRF51822 has non-modifiable ID registers. For example, is this the case for FICR's DEVICEID, and the Bluetooth address?

Thanks!

Hi Timo,

All the content in the FICR area, such as DEVICEID/DEVICEADDR, is non-modifiable.

Cheers, Håkon
