Is it possible to get the hardware version from the application that has been defined in the DFU ? (NRF_DFU_HW_VERSION)

[Aurele]

Hello,

I would like to kwno if it is possible to get information about the hardware in my main application. NRF_DFU_HW_VERSION is stored in the DFU and is used to verify hardware compatibility but i don't know if it can be used in the application or at least how it can be retrieved. 

Moreover, can i add information in NRF_DFU_HW_VERSION and not only the CPU used ?

Regards,

Aurélien

Hello,

The NRF_DFU_HW_VERSION value is not stored at a fixed address in flash by default. I would suggest to store it in one of the available UICR registers so it can easily be accessed by both app and bootloader. 

You can use your own version scheme for NRF_DFU_HW_VERSION, this is also recommended.
