Connectivity Test Application
The Connectivity Test Application is a SMAC based Demo Application which provides the user with means to test basic transmission-reception functionalities along with several advanced testing features based on the ASP and SMAC APIs.
Configuration
The runtime configuration is performed using shortcut keys which are available in most of the application’s menus. The menus or tests will change their behavior based on what settings are applied.
Connectivity Test
Shortcuts Menu- 't' - brings up the configuration menu for the transmitter in both PER and Range tests.
- 'r' - brings up the configuration menu for the receiver in both PER and Range tests.
- 'q' - increments channel number. [11-26]
- 'w' - decrements channel number. [11-26]
- 'a' - increments output power value.
- 's' - decrements output power value.
- 'n' - increments the length of the payload (used in PER TX and Transmission Control).
- 'm': decrements the length of the payload (used in PER TX and Transmission Control).
- 'k' - increments the CCA threshold for the Carrier Sense test.
- 'l' - decrements the CCA threshold for the Carrier Sense test.
Application usage
The Connectivity Test Application has four main features:
- Continuous Tests: Allows you to test the RF performance of the transceiver for basic transmitter and receiver functionality. The Test Mode application is a collection of modes consisting of the following tests:
- Packet Error Rate: This menu depends on the 'r' or 't' shortcut key. Two boards are required to run this test, one of the boards shall be set in RX and the other in TX.
- Range Test: This menu depends on the 'r' and 't' shortcuts. Two boards are required to run this test; the test is started and stopped only by user intervention and during its execution it will display the link quality for each received packet.
-
Carrier Sense and Transmission Control:
This menu allows the user to choose between two tests:
The Carrier Sense test performs ED continuously until the ED value is above the CCA threshold and then transmit a packet which contains pseudo-random data with the payload size configured using 'n' and 'm' shortcuts.
The Transmission Control test displays a selection menu for number of packets identical with the one in PER TX test and then it prompts the user to enter the inter-packet delay. After that, the application will start sending the selected number of packets with the selected inter-packet delay, using pseudo-random data for the payload with the size configured with 'n' and 'm' shortcuts.
For additional details on how to run the Connectivity Test Application, please refer to the SMAC’s Demonstration Applications User’s Guide.
Running a demo using IARDownload PDF
1. Build the platform library
These steps show how to open a demo workspace in IAR Embedded Workbench, how to build the platform library required by the demo, and how to build the demo application. The example used below is for the hello_world demo, but similar steps can be applied to any demo in the KSDK.
-
Open demo workspace (*.eww file) in:
/examples/frdmkl43z/demo_apps/ /iar After the workspace is open, two projects are shown: one for the KSDK platform library and one for the demo. Also, the platform library project is bold, indicating that it is the active project. The active project can be changed at any time by right clicking on the desired project and selecting "Set as Active" or via the build target drop-down at the top of the workspace browser.
-
There are two project configurations (build targets) supported for each KSDK project:
- Debug - Compiler optimization is set to low, and debug information is generated for the executable. This target should be selected for development and debug.
- Release - Compiler optimization is set to high, and debug information is not generated. This target should be selected for final application deployment. The tool allows you to select either the Debug or Release configuration on a per-project basis, but since the demo has a dependency on the platform library, whichever configuration is selected for the demo must also be selected for the platform library. Selecting a configuration in the drop-down also makes whichever project and configuration that is selected the active project. For this example, select the "ksdk_platform_lib – Debug" target.
-
Click the "Make" button, highlighted in red below.
-
When the build is complete, the library (libksdk_platform.a) is generated in one of the following directories, according to the chosen build target:
/lib/ksdk_platform_lib/iar/KL43Z4/debug /lib/ksdk_platform_lib/iar/KL43Z4/release
2. Build a Demo Application
The KSDK demo applications are built upon the software building blocks provided in the Kinetis SDK platform library, built in the previous section. If the platform library is not present, the linker displays an error indicating that it cannot find the library. An easy way to check whether the library is present is to expand the Output folder in the ksdk_platform_lib project. If the platform library binary is not built and present, follow the steps on page 1 to build it. Otherwise, continue with the following steps to build the desired demo application.
-
If not already done, open the desired demo application workspace (*.eww file). This example's workspace file is located in:
/examples/frdmkl43z/demo_apps/hello_world/iar -
Select the desired build target from the drop-down. For this example, select the "hello_world - Debug" target.
-
To build the demo application, click the "Make" button, highlighted in red below.
-
The build will complete without errors.
3. Run a Demo Application
The FRDM-KL43Z board comes loaded with the PE micro debug interface from the factory. If you have changed the debug OpenSDA application on your board, visit http://www.nxp.com/opensda for information on updating or restoring your board to the factory state.
-
Connect the development platform to your PC via USB cable between the "SDAUSB" USB port on the board and the PC USB connector.
-
Open the terminal application on the PC (such as PuTTY or TeraTerm) and connect to the debug COM port you determined earlier. Configure the terminal with these settings:
- 115200 baud rate
- No parity
- 8 data bits
- 1 stop bit
-
Click the "Download and Debug" button to download the application to the target.
-
The application is then downloaded to the target and automatically runs to the main() function.

Programming the USB-KW40Z using J-Link
This document describes how to update or program a new application in the USB-KW40Z using J-Link debugger.
USB-KW40Z contains two MCUs that need to be programmed depending on the desired use case. Hence, USB-KW40Z contains two connectors to program the board. These connectors are shown in the figure 1 as "SWD MKW40Z" and "JTAG MK22F".
Figure 1. USB-KW40Z Hardware
When an application needs to be programmed in the MK22FN512 MCU, "JTAG MK22F" connector is used. Different from this, "SWD MKW40Z" connector is used when programming KW40Z device. In order to be able to program an application to the USB-KW40Z using JLink, ".bin" files are needed because it is the format that JLink application requires in order to be able to program a board. Please, follow the next steps to program USB-KW40Z.
-
Locate the .bin file that need to be programmed in the USB-KW40Z. In this case, this file is the one downloaded from the "Getting Started" web page.
-
Go to JLink installation path. (i.e. "C:\Program Files (x86)\SEGGER\JLink_V502")
-
Copy and paste the ".bin" file into the JLink installation path. Just as an example, in this document, a file called "usb-kw40z_cmsis-dap.bin" for the MK22FN512 MCU will be used.
-
Make sure that Jlink debugger is connected to the corresponding JTAG MK22F connector (J6) in the USB-KW40Z.
Figure 2. JLink debugger connected to JTAG MK22F connector
-
Go the JLink installation path, and then open the application "JLink". Windows shown in figure 3 will be displayed.
Figure 3. JLink application
-
Call the next instructions in next order:
-
unlock kinetis
-
device mk22fn512xxx12
-
loadbin usb-kw40z_cmsis-dap.bin 0
-
-
One important thing to note in the step 6 is the "loadbin" command. The name of the file to be programmed in the MCU is specified in this command. In this case, "usb-kw40z_cmsis-dap.bin" is used as an example for this document.
-
A success or "O.K." message should be displayed in the window once the binary file is downloaded.
-
Disconnect and reconnect the board.
-
Now, an application to the K22F MCU was successfully downloaded.
