Please suggest any tutorial on Firmware/Application Software update for nRF52832/40 using BLE. What all changes need to be done on device software to do DFU?

I followed this tutorial from Nordic to set up DFU on my nRF52-DK.  I have since applied this same approach on my custom board using an nRF52832 chip

Cheers,

Hi I have the following setup...macOS, python and pip3.8 installed and nrfutil is also installed. Now how should I open/run nrfutil from terminal. When I go to the folder in which I have downloaded nrfutil and open it with terminal. I get the following message

When I enter nrfutil -h command on the terminal, it says no such command exists whereas when I enter pip3 -h it gives the list of commands. Both are in the same folder user/sg/library/python/3.8/bin

Thanks

Hello,

Which link are you following to implement dfu..? The tutorial provided here explains in detail how to update firmware for the nrf5340: https://github.com/simon-iversen/ncs_samples/tree/master/update_mcuboot_app_and_netcore It is provided in the last section of the tutorial shared previously: Add DFU support to your application 

Best Regards,
