SDK 13.0.0 Buttonless DFU won't enter boot mode

[Mark P. Mendelsohn]

Starting notification and then writing 0x01 to the control point does not cause the Buttonless DFU to enter boot mode. LED #1 remains on.

Run time trace show:

APP:INFO:advertising is started
APP:INFO:Connected
APP:INFO:Received indication state 0, notification state 1

Log from LightBlue shows:

Do you see the same issue if you're using the nRF Toolbox app for iOS to perform a DFU using one of the test images from the SDK?

Here are my screen shots of the procedure. Please send me your working ones. Thanks.

Resolved by creating a Settings File and merging with the SoftDevice, Bootloader and Application.

Hello, can you describe more precisely what you did? I have the same problem. I merged the bootloader and the bootloader_settings.

At the package generation, I generate a SD+BOOT+APP with the merged_boot.hex file. I can't programm it via DFU.

I also tried to programm the merged.hex by means of nrfgostudio. That doesn't work either
