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.
