It works!

There were no soft device in both HolyIOT dongles when delivered as you said.

Thank you so much Siguard.

Hi!

"Failed with exit code 1. One or more program tasks failed: * ED6CF1F60BA7: Internal sdfu error: Response failure from packet: DfuResponse { opcode: ObjectExecute, result: ExtError, extended_error: SdVersionFailure, response: None } (Generic) Message: Failed, Internal sdfu error: Response failure from packet: DfuResponse { opcode: ObjectExecute, result: ExtError, extended_error: SdVersionFailure, response: None }."

SdVersionFailure means the bootloader rejected the update because the SoftDevice the package requires isn't on the board. I get exactly the same error on nRF52840 dongle, if I write only the application hex while the board has no S140 v7.2.0. If I add s140_nrf52_7.2.0_softdevice.hex (components/softdevice/s140/hex) together with the application hex in the Programmer app, it goes through. Please try that.
