Hi,

I am not aware of any, and we do not have any official support for that either. However, there should not be a big fundamental difference, as the DFU procedure is the same regardless of how you obtain the data (reading it from flash or receiving on a serial interface, the data will be the same).

Hi,

Thanks a lot for the reply. Maybe is the some example how to take data from UART (not find image inside flash memory ) and transmit to the target?

Thanks!

Hi,

We do not have any DFU master implementation for the nRF5 SDK secure bootloader. So if you need that you have to implement it yourself. This has been done before, and here are some examples of that using serial transport.
