BLE DFU OTA using nrfutil possible?

rsf

Hello,

i have a device supporting DFU OTA i'd like to create a small tool for flashing firmware from the computer to the device. I've set thr device to DFU mode. Is it possible to upload the firmware using nrfutil?

i've tried:

nrfutil dfu ble -pkg fwpkg.zip -ic NRF52 -n "DfuTarg" -f

but that didn't work out. i receive:

Error:
No boards found.

am i doing something wrong?

best

    Hello,

    Yes, it is possible to update the target device over BLE using nrfutil, but you need another nRF kit in order to do so. 

    This:

    Error:
No boards found.

    Comes from nrfutil, because it is looking for a DK to use as the BLE device (connectivity board) that will transfer the new application image to your target device.

    So you need a spare nRF5x DK, or an nrf52840 dongle (the one made by Nordic Semiconductor).

    Best regards,
