The DFU Nordic samples have a 4K "MBR Params" page, located in the last 4K of flash. e.g., the linker file has:
MBR_PARAMS_PAGE (rw) : ORIGIN = 0x0007E000, LENGTH = 0x1000
And, the DFU library code references it:
uint8_t m_mbr_params_page ...
Hi, I want to use iOS to connect nRF82832 with passkey when connecting. I use pca10040_s132 with SDK 12.2.0.
