Setting the BD address
Posted byUnicycleBloke155 points 2 repliesDA14531 with SDK 6.0.14
I'm confused about how the BD address is made unique for each device for production. The SDK has a static const data structure in which the address is set with a macro.
Can someone please explain how this works?
I have same question for the DISS, which contains a serial number that should vary between devices.

Thanks for the response on the BD address - that's very clear. I guess the device get a new random address after power on. I can see that it is stored in retained memory.
For the DIS I meant APP_DIS_SERIAL_NB_STR - I assumed that this is intended to be something that is unique to each device. This is not so important, but I wondered if a dynamic DISS is possible with the SDK.

Hi UnicycleBloke,
You can set the USER_CFG_ADDRESS_MODE macro to APP_CFG_ADDR_STATIC in the user_config.h header file.
Then you should use either default_app_generate_unique_static_random_addr() or default_app_generate_static_random_addr() API in.app_on_generate_static_random_addr callback in user_callback_config.h file.
Please first check the comments above those APIs in app_default_handlers.h.
With regards to your question about the DIS, I assume that you mean the “DIS System ID”. You can set your preferable ID be configuring the APP_DIS_SYSTEM_ID in user_profiles_config.h
Thanks, PM_Dialog
