Thank you, I guess I'll have to build it myself then.

Hi,

Unfortunately, we don't have the example code as per your requirement.

The only source of documentation we have for now is DFU protocol on the info center. It defines the opcode and the message sequence chart you can follow.

I have read the tutorial and checked the DFU master code. I couldn't find if this allows for secure updating or that this is working in open mode.

Currently we don't have an official DFU Master code running on embedded chip (for example updating an nRF52 from another nRF52 via BLE or UART/SPI). 
What we officially provide is source code for updating nRF52 from a PC or Mobile phone.

What I am interested in is that I am able to run secure DFU master code on embedded chip both using BLE and UART as a means to update another chip.

This example looks more like that both transport layers are implemented on the receiver side, not on the host side. I do not know if I need to write my own code to perform as an host.

Hi,

My colleague provided the DFU master code in this tutorial and SDK v15.2 combining the BLE+UART DFU example in this post.
