Requirements

Supported toolchains (make variable 'TOOLCHAIN')

  • GNU Arm® Embedded Compiler v11.3.1 (GCC_ARM) – Default value of TOOLCHAIN
  • Arm® Compiler v6.22 (ARM)
  • IAR C/C++ Compiler v9.50.2 (IAR)

Supported kits (make variable 'TARGET')

Hardware setup

This example uses the board's default configuration. See the kit user guide to ensure that the board is configured correctly.

Software setup

This code example consists of two parts: a Broadcaster and an Observer.

For the Observer, download and install the BLE Scanner app for Android or an equivalent app for iOS.

Install a terminal emulator if you don't have one. Instructions in this document use Tera Term.

This example requires no additional software or tools.

Using the code example

Create the project

The ModusToolbox™ tools package provides the Project Creator as both a GUI tool and a command line tool.

Use Project Creator GUI

  1. Open the Project Creator GUI tool.

    There are several ways to do this, including launching it from the dashboard or from inside the Eclipse IDE. For more details, see the Project Creator user guide (locally available at {ModusToolbox™ install directory}/tools_{version}/project-creator/docs/project-creator.pdf).

  2. On the Choose Board Support Package (BSP) page, select a kit supported by this code example. See Supported kits.

    Note: To use this code example for a kit not listed here, you may need to update the source files. If the kit does not have the required resources, the application may not work.

  3. On the Select Application page:

    a. Select the Applications(s) Root Path and the Target IDE.

    Note: Depending on how you open the Project Creator tool, these fields may be pre-selected for you.

    b. Select this code example from the list by enabling its check box.

    Note: You can narrow the list of displayed examples by typing in the filter box.

    c. (Optional) Change the suggested New Application Name and New BSP Name.

    d. Click Create to complete the application creation process.

Use Project Creator CLI

The 'project-creator-cli' tool can be used to create applications from a CLI terminal or from within batch files or shell scripts. This tool is available in the {ModusToolbox™ install directory}/tools_{version}/project-creator/ directory.

Use a CLI terminal to invoke the 'project-creator-cli' tool. On Windows, use the command-line 'modus-shell' program provided in the ModusToolbox™ installation instead of a standard Windows command-line application. This shell provides access to all ModusToolbox™ tools. You can access it by typing "modus-shell" in the search box in the Windows menu. In Linux and macOS, you can use any terminal application.

The following example clones the "Bluetooth® LE Multi Beacon" application with the desired name "BluetoothLEMultiBeacon" configured for the CY8CKIT-062S2-43012 BSP into the specified working directory, C:/mtb_projects:

project-creator-cli --board-id CY8CKIT-062S2-43012 --app-id mtb-example-btstack-freertos-multi-beacon --user-app-name BluetoothLEMultiBeacon --target-dir "C:/mtb_projects"

The 'project-creator-cli' tool has the following arguments:

Argument Description Required/optional
--board-id Defined in the field of the BSP manifest Required
--app-id Defined in the field of the CE manifest Required
--target-dir Specify the directory in which the application is to be created if you prefer not to use the default current working directory Optional
--user-app-name Specify the name of the application if you prefer to have a name other than the example's default name Optional

Note: The project-creator-cli tool uses the git clone and make getlibs commands to fetch the repository and import the required libraries. For details, see the "Project creator tools" section of the ModusToolbox™ tools package user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mtb_user_guide.pdf).

Open the project

After the project has been created, you can open it in your preferred development environment.

Eclipse IDE

If you opened the Project Creator tool from the included Eclipse IDE, the project will open in Eclipse automatically.

For more details, see the Eclipse IDE for ModusToolbox™ user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mt_ide_user_guide.pdf).

Visual Studio (VS) Code

Launch VS Code manually, and then open the generated {project-name}.code-workspace file located in the project directory.

For more details, see the Visual Studio Code for ModusToolbox™ user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mt_vscode_user_guide.pdf).

Keil µVision

Double-click the generated {project-name}.cprj file to launch the Keil µVision IDE.

For more details, see the Keil µVision for ModusToolbox™ user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mt_uvision_user_guide.pdf).

IAR Embedded Workbench

Open IAR Embedded Workbench manually, and create a new project. Then select the generated {project-name}.ipcf file located in the project directory.

For more details, see the IAR Embedded Workbench for ModusToolbox™ user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mt_iar_user_guide.pdf).

Command line

If you prefer to use the CLI, open the appropriate terminal, and navigate to the project directory. On Windows, use the command-line 'modus-shell' program; on Linux and macOS, you can use any terminal application. From there, you can run various make commands.

For more details, see the ModusToolbox™ tools package user guide (locally available at {ModusToolbox™ install directory}/docs_{version}/mtb_user_guide.pdf).

Operation

  1. Connect the board to your PC using the provided USB cable through the KitProg3 USB connector.

  2. Open a terminal program and select the KitProg3 COM port. Set the serial port parameters to 8N1 and 115200 baud.

  3. Program the board using one of the following:

    Using Eclipse IDE

    1. Select the application project in the Project Explorer.

    2. In the Quick Panel, scroll down, and click <Application Name> Program (KitProg3_MiniProg4).

    In other IDEs

    Follow the instructions in your preferred IDE.

    Using CLI

    From the terminal, execute the make program command to build and program the application using the default toolchain to the default target. The default toolchain is specified in the application's Makefile but you can override this value manually:

    make program TOOLCHAIN=<toolchain>

    Example:

    make program TOOLCHAIN=GCC_ARM

  4. After programming, the application starts automatically. Confirm that "<CE Title>" is displayed on the UART terminal.

    Do the following to test using the mobile app:

    1. Turn ON Bluetooth® on your mobile device.

    2. Launch the respective app for iOS or Android.

    3. Press the reset switch on the kit to start sending advertisements.

    4. Refresh your app screen to see one Eddystone data and one iBeacon packet: UUID.

      Figure 1. Eddystone-URL and iBeacon-UUID advertisement

  5. Use the KitProg3 COM port to view the Bluetooth® stack and application trace messages in the terminal window.

    Figure 2. Log messages on KitProg3 COM port

Debugging

You can debug the example to step through the code.

In Eclipse IDE

Use the <Application Name> Debug (KitProg3_MiniProg4) configuration in the Quick Panel. For details, see the "Program and debug" section in the Eclipse IDE for ModusToolbox™ user guide.

Note: (Only while debugging) On the CM4 CPU, some code in main() may execute before the debugger halts at the beginning of main(). This means that some code executes twice – once before the debugger stops execution, and again after the debugger resets the program counter to the beginning of main(). See KBA231071 to learn about this and for the workaround.

In other IDEs

Follow the instructions in your preferred IDE.

Design and implementation

The ‘Bluetooth® LE Multi Beacon’ is a GAP Broadcaster. It advertises one Eddystone data: URL (www.infineon.com) and one iBeacon packet: UUID.

The Multi Beacon example uses the multi_advertisement functions to set data and parameters for two sets of advertisement. There are utility functions which helps set the advertisement data in the specific format required by the Eddystone and iBeacon specifications.

The Bluetooth® device boots up, initializes the BT stack, sets the two sets of advertisement data, and starts the advertisement.
