You will need to implement your own custom transport layer to support DFU over i2c. Fortunately, the bootloader is designed so that it should be easy to add custom transport layers. The documentation <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.sdk5.v15.3.0/lib_dfu_transport.html?cp=5_0_3_5_2"><strong>here</strong> </a>outlines the requirements for the transport layer. You may also use the existing UART transport as a reference.&nbsp;</p> <p>2. i2c is not supported by nrfutil. So you need a custom DFU master or a way to bridge the UART communication from nrfutil to i2c.&nbsp;&nbsp;</p><div style="clear:both;"></div>
