Before you start developing, program and run a precompiled application on your
development kit to ensure that the kit functions as expected and the communication between your
computer and development kit works.
-
Download the Heart Rate Monitor (HRM) demo application from nRF5340 DK Downloads and extract it into a folder of your choice.
There will be two HEX files in the folder, one for the application core (peripheral_hr.hex) and one for the network core (hci_open_amp.hex).
-
Install nRF Connect for Desktop and nRF Connect Programmer.
-
Use nRF Connect Programmer to program the HEX files of the demo application.

Press the
reset button.
The development kit will now restart and run the application. Note that while
restarting, the JLINK drive will be disconnected.
