Use an nRF5 Development Kit (DK) as the connectivity device for the
Device Firmware Update (DFU) over Bluetooth®
Low Energy
procedure.
Complete the following steps to do the DFU:
-
Connect an nRF5 DK to your computer.
Note: In the -ic option, you must specify if the DK contains an
nRF51 or nRF52 chip.
-
Run nrfjprog --eraseall to erase the contents of the
DK.
-
Run nrfutil dfu ble to do a full DFU
over Bluetooth Low Energy.
Use the -f option to program the DK
with the required connectivity software. This option overwrites the contents
of the DK.Enter nrfutil dfu ble --help to see
available options.
For example, to perform a DFU procedure using
app_dfu_package.zip over
Bluetooth Low Energy on an nRF52 device
connected to COM3, where MyDevice is the remote
Bluetooth Low Energy device
being upgraded, enter the following
command:
nrfutil dfu ble -pkg app_dfu_package.zip -ic NRF52 -p COM3 -n "MyDevice" -f
