Serial DFU with nRF9160 as DFU controller

[esisk]

I'm downloading a firmware image from AWS via cell onto the nRF9160. I want to perform a serial DFU over UART. The DFU target is the nRF52840. Are there any existing samples outlining this process?

When building this, should I clone the repository into my current ncs directory? I have it cloned outside right now and getting issues with west build

Hi Ethan, 
You should clone it to the NCS v1.4.0. 

Or you can look at these 2 commits to know what has been modified:

Thanks Hung, do you think trying to use this code is going to be an issue if we're using NCS v1.5.1?

I would suggest to try testing the code with v1.4.0 first and after you get it running, you can study the code and try to port it to v1.5.1.

I'm not very familiar with the code but I think it's better to try step by step.

Thanks!
