Hi all,
I am trying to send dfu_application.zip from nrf toolbox to board(nrf52840) in zephyr but it shows fails,
how can i send .zip file
Thank you
Try using the .bin file instead. More specifically, use the file <sample>/<build folder>/zephyr/app_update.bin.
By the way, we have created an app dedicatd to mcumgr (which is the protocol you're using I assume), the nRF Connect Device Manager app.
