1.1 Get Familiar with Rapid IoT Prototyping Kit
Let's take your Rapid IoT Prototyping Kit for a test drive. You have the choice of watching the sequence in a short video or following the detailed actions listed below.
1.2 Unboxing
Here is an overview of the Rapid IoT box.
- Begin by opening the box and reviewing the kit content. The Rapid IoT unit comes with a printed Quick Start Guide, a SIM tool, and a micro-USB cable
- The printed Quick Start Guide provides useful information like the location and the numbering of the Touch or Push buttons as well as the menu architecture of the Factory application
1.3 Power On
Begin by charging the battery of your Rapid IoT. Connect one end of the micro-USB cable to your computer USB port (or to any USB charger) and the other end to the micro-USB connector of your Rapid IoT board.
The RGB and White/Blue LED’s on the top front will blink for few seconds to confirm that the preprogrammed Bootloaders loaded successfully (more details in the dedicated chapter).
While the factory application is loading the NXP and the Atmosphere logos will be displayed.
Then the Welcome menu with the Rapid IoT logo and the clock will show up on your Rapid IoT screen.
With the help of the printed Quick Start Guide, you can navigate through the different screens with the Touch electrodes, and change the options with the Push buttons.
The factory application divides into four main categories: Application, Settings, Info, and Sensors.
From the Application section, you can access mini-Apps that leverage the sensors onboard in different use-cases such as a thermostat, barometer, air-quality, motion or fall detection, or color-light controller.
From the Settings section, you can change the Wireless mode (Bluetooth or Thread), enable/disable the internal access to the NFC-tag or the Sensor-tag (Sensor data pushed through wireless), turn on/off the buzzer or the screen backlight, or restart your Rapid IoT board.
From the Info section, you can verify the version of the firmware programmed in your board or scan the QR code to quickly download the Android or iOS Phone App to monitor/control your Rapid IoT over Bluetooth.
From the Sensors section, you can enable/disable each sensor onboard to create your custom monitoring profile and extend your Rapid IoT battery lifetime.
By default, the application is configured to stream all the sensor data (Sensor tag) over Bluetooth radio to an Android or iOS Phone/Tablet. Thanks to the dedicated phone App the sensor data will be automatically pushed through WiFi or Cellular connectivity to the Cloud.

From the Studio view under CREATE PROJECT select New Project to create a new project.
From the NEW PROJECT window enter your new project name (ex. BLE Light Sensor) and press the button CONFIRM.
A new blank NXP RAPID IOT workspace will appear.
Embedded View
Embedded View is a workspace in Atmosphere Studio for developing an IoT project's embedded firmware. While in Embedded View, the Element Toolbox displays elements that execute on the project's end device. Embedded elements operate as a bridge between the embedded firmware and device interacting with it.
Embedded View's toolbar includes access to the code editor and the programmer.
Code editor is an advanced text editor for writing and modifying the embedded code of a project.
Click the Code Editor button to display the embedded code
editor beside
Embedded View's canvas.
While the code editor is open, any embedded element selected in the
canvas has
its corresponding code
highlighted.
In addition to being added to the canvas, embedded elements may have their source code customized when added to the canvas and when connected to other elements. While most elements do not require their code to be customized and are designed to operate as-is, the option is available to expand their functionality through custom code. The function element for example is a blank slate element, which relies entirely on customizing code to your liking.
The default headers in the code editor include an area to define variables and custom functions, an interval function, a connected function, a disconnected function, and a setup function.
Elements are blocks of code that perform a variety of programmable functions within Studio. Located within the Element Toolbox's elements panel, elements enable the functionality, visualization, and cloud connectivity for an Atmosphere project.
Elements are added to a view canvas from the Element Toolbox to visually construct your project,
and may also
be clicked within the toolbox and added directly to the canvas.
For this project, we want to use Bluetooth to send ambient light sensor data to a mobile application. To accomplish this, we only need four elements: a time interval, display text, the light sensor and a BLE GATT characteristic.
To add the elements, select individually the following items in the Element Toolbox located in the right panel:
Selecting an element in the canvas displays its properties in the Element Toolbox's properties panel. Each element has a set of default properties and functionality included within them. Properties vary based on the element, and may be changed based on their needs.
To remove an element, select it in the canvas, then remove it pressing Delete or using the Trash Can button in the element's properties.
When all the Elements have been added to your canvas, your workspace should look like as below.
Elements on the canvas can connect to one another to create a chain of functionality between them
by using a
"connector." Connectors represent the flow of information from a "source" (beginning) element to
a "target"
(ending) element.
To
create a connector, click and hold the edge of the source element, then drag the cursor
to the
target element and release it.
Now connect the Elements like represented below.
When two elements become connected, it creates an "event" between them. Events define the actions that occur between the source and target element.
Events can be modified either in the source element's properties, or by selecting the connector's Configuration button between the two elements. Events consist of the following:
- The trigger that causes the event
- The target element
- The target element's ability
- Any ability arguments
When adding the Bluetooth Element to our Workspace, Studio automatically configured the UUIDs and sets some default settings, but we still need to adjust some parameters for our specific need.
From the Workspace, select the Bluetooth Element to display its Properties in the right panel. Disable the options Write and Notify since we will output the Light Sensor data via Bluetooth. Change Data Type from String to Unsigned Integer to display properly the Ambient Light value.
Coupled Elements, like Bluetooth Element, bridge a project's functionality across one view to another.
When a coupled element is added to the canvas, it creates a corresponding copy of it on an associated view (likewise, deleting a coupled element will remove its copy). This allows the element to extend its functionality to that view. Clicking on a coupled element's badge moves you to that view with that element selected and its properties displayed.
Application View
Application View is a workspace in Atmosphere Studio for developing a phone App interface that interacts with the NXP Rapid IoT hardware. Application View also acts as a gateway between Embedded View and Cloud View, and is used to have data sent from the embedded firmware up to Atmosphere Cloud.
Open the Application view from the upper Project toolbar.
You’ll notice that a Bluetooth Element has been automatically added to the Application Workspace. It is coupled to the Bluetooth Element from the Embedded application.
Now we need to configure the mobile application. First, we need an interval to determine how often to read data from the Rapid IoT. Afterward, we need to display properly the data on the phone screen.
While in Application View, the Element Toolbox displays elements that execute on the application, which includes visual elements that represent interface components and functional elements that run in the background.
Select individually the following items in the Element Toolbox to add them to your Application Workspace.
Select the Element Label in the Workspace.
Change its PROPERTIES NAME to
SensorData and remove TEXT information.
Select the Element Label1 in the Workspace.
Change its PROPERTIES NAME to
Title and TEXT
to Ambient Light (lux)
The APP VIEW window located in the left side provides an overview of the phone App interface. Place the Title and the SensorData at the preferred location on the phone screen.
Now, add connectors as shown below. The title label doesn’t need to be connected to anything since it just displays static text.
There is no additional configuration needed for the Application.
Now, we need to select layouts that our application will support. To do this, select the little phone icon next to the resolution drop-down.
In the window that pops up, select any devices you want to support (your device or the closest match).

MCUXpresso Software Development Kit (SDK) + Integrated Development Environment (IDE)
MCUXpresso SDK Architecture
The Rapid IoT SDK is a composite SDK. It features two SDK target specific SDKs, for each target MCU in the Rapid IoT device.
Each target specific SDK features a similar structure to traditional MCUXpresso SDKs. Under the ‘rapid_iot_apps’ directory you will find the factory installed applications on your Rapid IoT device.
The included K64F application is from the Atmosphere IDE, repackaged to this SDK format. The application’s code base has been split between ‘app_src’ (shown in Figure 220) and ‘middleware/atmosphere’ (shown in Figure 221). This provides a clean directory structure for users to copy and modify as needed.
The Atmosphere source is divided further into two groups. The first is shown above in Figure 221. The second is a static library that is illustrated in Figure 222. This static library features lower level code for application updating, connectivity, RTOS, etc.
For non-Atmosphere based projects (kboot(s) and rpk_kw41z_hybrid), there is a rapid_iot specific middleware directory. Figure 223 illustrates the stucture of this middleware folder.
