Getting Started with the QN9080SIP-DK

Import the MCUXpresso SDK

1. Open up the MCUXpresso IDE
2. Switch to the Installed SDKs view within the MCUXpresso IDE window
3. Open Windows Explorer, and drag and drop the QN9080SIP-DK SDK directory (installed at into the "Installed SDKs" view)
4. You will get the following pop-up. Click OK to continue the import:
5. The installed SDK will appear in the Installed SDKs view as shown below:

Build a BLE Application

The following steps will guide you through opening the hybrid example. This project will be loaded to one board, while another project will be loaded on the 2nd board.

1. Find the Quickstart Panel in the lower left hand corner
2. Then, click on Import SDK examples(s)
3. Click on the QN9080SIP-DK board to select that you want to import an example that can run on that board, and then click Next

4. Now, we need to select the project to import. Use the arrow button to expand the "wireless_examples" category, and then under the "bluetooth" category expand the "heart_rate_sensor" project and select the "freertos" version of project

This particular project doesn't make use of the UART, but for projects that do, select the "UART" option for the "SDK Debug Console". Then, click on Finish


5. Now, build the project by clicking on the "qn908xcdk_wireless_examples_bluetooth_heart_rate_sensor_freertos" project name and then in the Quickstart Panel click on Build
6. You can see the status of the build in the Console tab. If you get a compile error, make sure you had imported two projects at the same

Download and run the application demo

1. Connect the first QN9080SIP-DK board to your PC if it is not already. Use the J2 USB connector on the QN9080SIP-DK
2. In the Quickstart Panel, click on "Debug "qn908xcdk_wireless_examples_bluetooth_heart_rate_sensor_freertos" [Debug]"
3. MCUXpresso IDE will probe for connected boards and should find the LPC-LINK2 CMSIS-DAP debug probe that is part of the integrated debug circuit on the QN9080SIP-DK. Click OK to continue
4. You may get the following error. Click OK to dismiss it
5. The firmware will be downloaded to the board and the debugger will start

Run the Heart Rate Sensor demo

1. Open the NXP IoT Toolbox application on your mobile device and click on the Heart Rate icon
2. On the QN9080SIP-DK board, press Button1 to begin BLE advertising
3. In the smartphone app, you should now see the "FSL_HRS" name. Click on it
4. The board will then connect to the phone, and you'll see a graph of the random "BPM" reading

The following steps will guide you through compiling, flashing and running a simple Heart Rate Sensor BLE application using the QN9080SIP-DK board.

Build a BLE Application

1. Navigate to the Heart Rate Sensor workspace (located at <install_dir>\boards\qn908xcdk\wireless_examples\bluetooth\heart_rate_sensor\freertos\iar)
2. After the workspace is open, select the project
3. Click the Make button to build the project

Download and Run the application demo

1. Connect the first QN9080SIP-DK board to your PC if it is not already. Use the J2 USB connector on the QN9080SIP-DK
2. Open the terminal application on the PC (such as PuTTY or Tera Term) and connect to the debug COM port you determined earlier. Configure the terminal with these settings:
3. Click the "Download and Debug" button to download the application to the target
4. The firmware will be downloaded to the board and then you may see the following message. Check the "Don't show again" checkbox and then click on the Yes button
5. The debugger will then be started. Click on the "Go" button to begin running the demo

Run the Heart Rate Sensor demo

1. Open the NXP IoT Toolbox application on your mobile device and click on the Heart Rate icon
2. On the QN9080SIP-DK board, press Button1 to begin BLE advertising
3. In the smartphone app, you should now see the "FSL_HRS" name. Click on it
4. The board will then connect to the phone, and you'll see a graph of the random "BPM" reading

Install CMSIS device pack

After the MDK tools are installed, Cortex® Microcontroller Software Interface Standard (CMSIS) device packs must be installed to fully support the device from a debug perspective. These packs include things such as memory map information, register definitions and flash programming algorithms. Follow these steps to install the appropriate CMSIS pack.

1. Open the MDK IDE, which is called µVision. In the IDE, select the "Pack Installer" icon
2. In the Pack Installer window, search for "qn" to bring up the QN908x family. Click on the QN908x name, and then in the right hand side you'll see the NXP::QN908x_DFP pack. Click on the "Install" button next to the pack. This process requires an internet connection to successfully complete
3. After the installation finishes, close the Pack Installer window and return to the µVision IDE

Build an Example Application

The following steps will guide you through opening the heart_rate_sensor BLE demo.

1. Inside the MDK, go to Project → Open Project
2. Navigate to the Heart Rate Sensor workspace (located at <install_dir>\boards\qn908xcdk\wireless_examples\bluetooth\heart_rate_sensor\freertos\keil) and open the "heart_rate_sensor_freertos.uvprojx" project
3. To build the demo project, select the "Rebuild" button, highlighted in red
4. The build will complete without errors

Run an Example Application

1. Connect the first QN9080SIP-DK board to your PC if it is not already. Use the J2 USB connector on the QN9080SIP-DK
2. Click on the Start/Stop Debug Session button to download the code to the board and start debugging it
3. Run the code by clicking the "Run" button to start the application

Run the Heart Rate Sensor demo

Open the NXP IoT Toolbox application on your mobile device and click on the Heart Rate icon

In the smartphone app, you should now see the "FSL_HRS" name. Click on it

The board will then connect to the phone, and you'll see a graph of the random "BPM" reading
