OTA DFU Software Requirements

[Kaveh.M]

Three software seems to perform OTA DFU: nrfutil command line, nRF connect from desktop, nRF connect from mobile

Do I need all three of them? Are they part of Nordik SDK or they are stand alone SW? And are they only available for Windows or they can also be installed on raspberry pi Debian? 

Thanks

Hi!

You do not need all three of them, you can use whichever one you prefer.

They are not part of the nRF5 SDK, as the SDK is a software development kit that you can use to build applications with the MCU's. nRF Connect for Desktop, nRF Connect for Mobile and nRF Util are separate development tools that allow you to test the DFU capabilities of our MCU's. 

You will have to use the nRF5 SDK to enable DFU functionality on the MCU you are working with. 

nRF Util is just a Python package, so you should be able to install it on a Raspberry Pi. 

Best regards,

Is there a recommended tutorial or link to perform OTA DFU for nRF52932. 

I m using (+) Getting started with Nordic's Secure DFU bootloader, a step by step guide - Software Development Kit - nRF5 SDK guides - Nordic DevZone (nordicsemi.com) and I can not go past step B1a.

Hi!

Sorry about the late response but a huge portion of the technical support staff are on summer holiday at the moment, including the author of the tutorial you are using.

He will be back in a couple of days and I will have him take a look at it then. It's possible the tutorial needs to be updated.

Best regards,

Heidi

Hi Heidi. Yes, there are some missing details in the tutorial. I was able to figure it out myself. Thanks for the Support.
