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

I am using a custom dongle based on a nRF51 IC on a PC. The DFU is so much simple and faster over HCI. In some cases, the HCI DFU make sense and is more appropriate than performing the update over the air...

@bjorn-spockeli The UART/HCI bootloader example has been removed in SDK12, and there is no information about this in the SDK release notes... Moreover, the Device Firmware Update over a serial is disabled in the current version of nrfutil. Why this ? Could you elaborate a bit more ?
