Is it possible to perform a DFU using UART with the new SDK12?

[Sébastien Despont]

In sample project I didn't find any way to perform an update through UART like previous SDK. Nrfutil tool documentation specify that :

Performing a Device Firmware Update over a serial (UART) connection is disabled in the current version of nrfutil.

So, is it possible to perform a DFU using UART with the new SDK12?

Best regards

BLE is the only supported transport layer in SDK12 bootloader example: infocenter.nordicsemi.com/.../lib_dfu_transport.html

@metch (Christopher) : Yes, I agree that in some cases it is better to use the serial bootloader instead of the Over-the-Air BLE bootloader. Support for serial DFU has been removed from SDK v12 becasue the entire bootloader library needed to be rewritten in order to support Secure DFU and we prioritized the BLE transport layer for the SDK v12.0.0 release. We plan to add the serial transport layer in a future SDK release.
