Retaining Beacon Minor after upgrading Firmware

[james.eberhardt]

Hello;

I'm developing an application that advertises as a connectable peripheral. As such, it has an ID (think of it like a beacon minor).

I have 2000 of these devices.

How can I update the firmware on the device without needing to reset the ID of the device?

At the moment we are changing a "config.h" file in the project, compiling with Keil, and flashing the application onto the chip. Needless to say, it's taking an extremely long time.

The ble_app_beacon example in the SDK stores the Major and minor values in the UICR registers which are retained during firmware updates. I guess this is the same solution that @mariusheil is proposing :)
