It is using SD s112 v7.0.1
That this is a project that is in production for several years, and has managed dozens of DFUs on thousand of customers.

Command line :
nrfutil pkg generate (...) --sd-req 0xCD

I am not passing --sd-id curiously. Is this the issue ?

Hello,

The bootloader will check if the Softdevice version requirement specified by the DFU package matches the Softdevice version on the device. If it doesn't it will reject the update. This ensures the application can't be uploaded unless the target device has a compatible version of the Softdevice installed.

Can you show the arguments you use to generate the DFU package with nrfutil and let me know what Softdevice you use?

$ nrfutil pkg generate --help

  Generate a zip package for distribution to apps that support Nordic DFU OTA.
  The application, bootloader, and SoftDevice files are converted to .bin if
  supplied as .hex files. For more information on the generated package, see:
