Thank you for confirming that it worked. I had expected to see a different error in nRF connect for desktop. At least you should get a more accurate error message if you use nRF connect on Android or iOS.

Hi,

I see this change stated in the SDK release notes for SDK 16.0.0 "The bootloader now disallows upgrading the SoftDevice to another family". I knew we were not testing DFU between different SD families during release testing, but not that the bootloader would actively reject such update requests.

Can you try to remove the last "if statement" that is shown in the image below and see if you get the same result? You should have gotten an different error in nRF connect if it's actually the version check that fails.

Also, does the device start to advertise after the failed DFU attempt?

Best regards,

Vidar
