BD_ADDR changes and multiple BD_ADDR

Hi,

The application may change the address by calling sd_ble_gap_addr_set() and sd_ble_gap_addr_get():

Best regards,

I was born with the need to change BD_ADDR in the bootloader.
nRF5_SDK_15.3.0_59ac345\examples\dfu\secure_bootloader\pca10040_ble
In other words, I need to change BD_ADDR without using SoftDevice.

How to change BD_ADDR without using SoftDevice?

Hi,

All nordic examples use the softdevice for BLE communication. So if you don't want to use the default BT address that is programmed in the chip, then the application (even bootloader) need to set a new address using sd_ble_gap_addr_set(). You can write custom BT address to the UICR, and then the application (even bootloader) can check if there is a cusom BT address in UICR, and if there is, then it can call sd_ble_gap_addr_set() to set the custom BT address.
