Hi,

1. The reason for this address change is explained in the docs here: Buttonless Secure DFU Service without bonds. It's basically done to make it appear as a different device while in DFU mode.

2. Yes, this should work. Below is the nrfutil command you can use to generate a full Softdevice+bootloader+application DFU package to upgrade to SDK 17. What Softdevice FWID to pass to --sd-req and --sd-id depends on which Softdevice variants you use, check SD release notes to find the FWID for a particular Softdevice variant+version.

nrfutil pkg generate --hw-version 52 ^
--bootloader-version <bootloader version> ^
--sd-req 0x91 ^
--sd-id 0x0101 ^
--application-version <application version> ^
--application APPLICATION.HEX ^
--softdevice SOFTDEVICE.HEX ^
--bootloader BOOTLOADER.HEX ^
--key-file FILE sd_ble_app_dfu.zip

Hi, I'm testing the BOOTLOADER with DFU,

I'm using nRF connect on my Android device to send the ZIP files to my PCA10040 card.

I have some questions:

1) I noticed that the blue tooth MAC ADDRESS changes when I'm using the DFU protocol,

My nRF device MAC ADR is FD:A7:EC:76:BD:51 when I'm using it as UART BLE

My nRF device MAC ADR is FD:A7:EC:76:BD:52 when I'm using it as DFU

2) Today I'm using SDK12, but I intend to use the SDK 17 on the future, may I do the SOFTDEVICE, APLICATION and BOOTLOADER update using DFU BLE from SDK 12 to SDK 17 or I have to use JTAG programmer?

Hi Carlos,

You can use the Experimental: Buttonless DFU Template Application as a reference to add buttonless support to your project. It may actually be quicker to start with this project and add the NUS service if you have just started development.

Best regards,
