There are 2 parts in the SDK:
- first part is the driver, which is in the
Driversdirectory. It contains Driver API doc, source code and examples on how to use the driver. - second part is the SDK in itself, in the
SDKdirectory. It contains everything to develop your own Fira-based application, (with CLI or UCI interface). It is based on Free RTOS, contains binary libs for Fira and IEEE 802.15.4z support, as well as the Drivers.
If you want to only run this example, the easiest would to start from the Driver example Segger Embedded Studio project which is in Drivers\API\Build_Platforms\nRF52840-DK directory.
If you want to start from the SDK, you should tweak the source code in order to remove the use of the fira library, and call the driver APIs by yourself.
