Device address fro public device address format

[Jeffery]

Hi In current Desktop 2 project, We know that software device stack takes 48-bit random device address from FICR registers (DEVICEADDR[1: 0]) for BTLE. Each nRF51 has unigue address. We are planning to apply public device address (compny_assigned + company_id) from IEEE. How can we replace FICR device address by it in nRF51? Then, no side effect at all.

A custom address can be put in UICR instead of FICR. As explained in the reference manual, addresses 0x080 - 0x0FC in UICR is reserved for custom usage, and can for example be written to using nrfjprog (see its --help for details). You'd still have to read the address from UICR and set it in the stack on boot, as Carles explains.

Did I just accidentally convert a comment to an answer while scrolling with this less-than-ideal touchpad? This should probably include a confirmation dialog "are you sure?".
