Windows Command line DFU over BLE with PCA10059

[Gaétan]

Hi,

I can make a DFU over BLE with nRF connect 2.5.0 Bluetooth Low Energy, all is OK.

I use my nRF52840-Dongle PCA10059 (Serial port: COM19 | USB: Nordic Semiconductor nRF52 Connectivity)



Now, I want to make the same with nrfutil command line tool: (v4.0.0)

nrfutil.exe -v -v -v -v dfu ble -ic NRF52 -pkg RavenDFU.zip -p COM19 -n "Raven" -f

But nrfutil don(t find the board:

pc_ble_driver_py.exceptions.NordicSemiException: board not found



What's the best solution to make DFU over BLE with nrf52840-Dongle ?



Regards,

Gaétan

Hi,

Try to remove the -f option. The -f option instructs nrfutil to actually program the board connected to COM19 with the connectivity software required to operate as a serialized SoftDevice. But the connectivity FW is already programmed to the dongle, so we don't need to do that.

If you get error code:3, then close nRF Connect app, and plug the dongle out and in again from the computer.

Thanks, it's OK when remove -f option.
