UART/HCI support of bootloader_secure in SDK 12

[fay2003hiend]

Hi

I have been trying to make a dual bank serial dfu bootloader with security features for nrf51822 (board 10028), but seems the UART/HCI dfu support is missing in SDK 12.

The previous SDK 11 has no secure feature, and the nrfutil for generating the package is from an even older Master Control Panel which I couldn't find a place to download?

Yes, the bootloader in SDK v12.0.0 currently only supports the BLE transport layer, see this Infocenter page.

You can download the pc-nrfutil tool that generates legacy firmware packages from this GitHub repository.

Hi Bjørn, could you please advise whether the HCI dfu with secure feature will be added in the future SDK?

We're planning to add Secure Serial DFU as experimental in the production release of SDK v13.0.0.
