Serial DFU Master example code

[Lorenzo]

Hi everybody,

I'd like to perform serial DFU on my nRF52832/nRF52840 based devices, using an external master MCU. Is there any reference C code for the master MCU?
In this post a Nordic employee reports that "My colleague provides an example of a very simple UART DFU master for nRF52 which you can study and try to translate into your ESP8266 controller", but the link is broken. Is such example still available, or do you have anything similar?

Thank you in advance

I suspect the link from the post you refer to is this one:

https://devzone.nordicsemi.com/guides/short-range-guides/b/software-development-kit/posts/getting-started-with-nordics-secure-dfu-bootloader

There is a DFU master project zip in near the bottom of the blog post. Please note that although it is included in the post, this project does not come from our SDK team, so it is not "SDK grade tested". It was written as a start help for a customer, and it was published in case it was useful for other customers as well. You can give it a try, and see if it works for you.

Note that it is written for an nRF52 as the master, but you can try to translate it into your ESP8266 controller, as you said. 

Best regards,

Edvin
