Deploying CCC Digital Key applications software

The software package includes the components necessary for CCC Digital Key R3 application development on the selected NXP platform. These components include:

  • Bluetooth Low Energy Host and Controller software libraries (KW38)

  • NBU image binaries

  • Examples of demo application projects corresponding to CCC Digital Key roles (Device and Car Anchor)

  • Platform peripheral drivers, platform startup code, other generic platform software

Note:

Prior to loading any wireless SDK example, update your NBU image with the provided binaries in the following folder of the SDK:

../middleware/wireless/ble_controller/bin.

The demo applications were compiled and tested with IAR Embedded Workbench for Arm and MCUXpresso IDE. It is recommended to use one of these tools.

To open, build, and run any example application, see the Bluetooth Low Energy Quick Start Guide document of the corresponding board. The CCC Digital Key R3 examples are built and run in the same fashion as Bluetooth Low Energy examples.

The Figure 1 shows the application folder structure for the digital_key_car_anchor project.

The relevant files for CCC Digital Key R3 are the following:

  • The main application source files source/digital_key_car_anchor.c and source/app_digital_key_car_anchor.c, and

  • The files in bluetooth/profiles/digital_key, which implement the Digital Key Service defined by the CCC Digital Key R3 specification.
