Hi,

To generate a HEX file that contains the Bootloader Settings page, see the nrfutil documentation/Generating and displaying keys for instructions.

Hi, thank you for your answer!

I am using Buttonless DFU Template as the reference. But I have one problem - if I flash this application after flashing S132 Softdevice and secure bootloader the application is not started. This is due to the fact that the application does not have a signature in the boot settings and, accordingly, the master bootloader does not allow it to start. This can be fixed by writing the bootloader settings to the flash, but how can I do this? If possible - give an example how to do it by bat file or Keil.

Thank you!

Hi,

You can use the Buttonless DFU Template Application as the reference or as a starting point to integrate the buttonless service into your application.

Notice that we are entering the Christmas and New Year holidays and will have reduced staff, please expect delayed responses until after January 4th. Sorry for the inconvenience.

What I want to get in the end: that among the BLE services of the main application there is a DFU service. And so that with a certain interaction with this DFU service, the chip goes into boot mode
