Hi Hung, can we get the updated version for 15.3 for this? And perhaps in SES instead of Keil since SES is free.
I actually need it for 52840 but at least if it comes in 15.3 I can try to port it. Right now it doesn't compile in 15.3 because of NRFX_SPI include issues. Or, please let me know if I should open a new ticket for this. Thanks!

Code for doing DFU from a nRF5x to a nRF5x via UART/SPI (DFU Master) can be found at appendix 5 in this blog.

Bjorn:

Is that still the current working python code? Github claims it to be pretty old.

No problem. I thought I'd ask before rolling my own. Let's hope it won't be too difficult ... ;)

Rob Philip: I am afraid that we still do not have any DFU host example in our nRF5 SDK. We do however have DFU support in our nRF SDK for Mesh, see this Infocenter page.

Hej Bjorn.

It's two years later and I have the same issue - updating the firmware of an nRF51 over BLE from my nRF52840. Any chance that someone has come up with a "host" example in the last two years?

Happy to help :)

Thank you for your answer! I'll have a look into that

@andresovela (Andy): No, we do not have any example where a nRF5x device updates the firmware of another nRF5x device. I suggest that you take a look at the BLE DFU Service Profile and Service Documentation, found here. It explains which charactersitics that should be written to and when they should be written to in order to initiate the DFU process. You could also take a look at the discussion in this question.

No, I mean the exact same situation as described by Uzair but using BLE instead of serial. When a host MCU has the binary and wants to flash another MCU by means of the DFU. Both MCUs are NRF51822.

@andresovela (Andy): Do you mean updating the firmware of the Host MCU over BLE?

Andy — Thu, 29 Sep 2016 13:28:24 GMT

Hi Bjorn, do you know if there is any example for the host MCU using BLE?

Unfortunatly, we do not have any examples for the "host" MCU for serial DFU since this the MCU used will vary from design to design.

I suggest that you take a look at our python implementation of the serial DFU in our nrfutil tool, found here on Github.

You can find a description of the serial packet format and in which order they should be sent on this Infocenter page.
