Adding Device Firmware Update (DFU/FOTA) Support in nRF Connect SDK

Having Device Firmware Update (DFU) or Firmware Over-The-Air (FOTA) support in an IoT product is becoming the norm now; it has become a standard requirement in modern products, and customers expect products to have it for security updates and improvements updates.

In this developer-oriented webinar, we will dive into the fundamental principles and best practices for adding DFU/FOTA support in an nRF Connect SDK-based firmware. We will focus on MCUboot as the default bootloader in the Zephyr RTOS, inherited by the nRF Connect SDK.

Good video and basic training guide on bootloading and DFU! Glad theres also a Nordic Semi DevAcademy trainjng on this too😄👍 Keep up such training videos Nordic Semiconductor!

Thank you for this video.
Can you explain how to do it with the SDK version 2.7.0 or 2.8.0, using sysbuild ?
I am struggling migrating from my v2.6.1 project using multi-image builds to sysbuild, even this the help of your dedicated page "Migrating from multi-image builds to sysbuild".
Thanks.

This is a great video and in conjunction with the DevAcademy course really helped me understand the process a lot better. If I wanted to incorporate this into my own app (vs nrf Connect mobile), how would I do that?

Great video, What is the bootloader and bootloader version onboard used here?

Hi, please can I program my nrf 52dk with an external jlink, my onboard jlink doesn't respond after trying all means

Nice video, however, how come the volume is so low?
