Plug It In

1.1 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.

Mark as complete:1.1 Unboxing

1.2 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.

IMPORTANT: The firmware programmed in factory is a public version that can be broadly distributed. The Rapid IoT board will be detected independently from the user-account used to login to the Phone App.

4.1 Atmosphere WEB/GUI-Programming tool

Atmosphere is a robust IoT platform for creating, deploying, and managing connected products. Atmosphere enables users to bring their IoT solutions to market quickly, affordably, and securely through a complete end-to-end experience.

The graphic below represents the typical architecture of connected products managed using Atmosphere.

All aspects of your connected product needs can be managed with Atmosphere no matter where you are in the process, from concept and prototype through deployment and management.

Unlike platforms that focus purely on developing embedded hardware or software, or managing devices, users, and data, Atmosphere accomplishes each of them simultaneously, providing the means to create and manage IoT solutions from start to finish. Atmosphere uses common connectivity protocols such as Wi-Fi and Bluetooth Low Energy to connect to your devices where it then receives device data, allowing for powerful aggregation, analysis, and reporting.

What is Included?

Atmosphere is composed of the following suite of applications:

Atmosphere IoT Platform: The Atmosphere IoT Platform is cloud-based software that offers a complete IoT development and management experience. Through its easy-to-use development environment, configurable dashboard editor, and device management console, Atmosphere provides you a single secure platform for every area of your IoT solution.

Atmosphere IoT App: The Atmosphere IoT app is a mobile app available in the Apple App Store and Google Play Store. The app is an extension of the Atmosphere IoT Platform, and enables you to use Atmosphere as you would from within a desktop browser, including registering and managing devices, viewing device data through dashboards, and more.

Atmosphere IoT Agent: The Atmosphere IoT Agent is a local application that runs in your computer’s system tray, and acts as an intermediary between the computer’s connectivity protocol drivers and the browser running Atmosphere. It is used for programming hardware, and enables you to program an end device from within the Atmosphere IoT Platform.

Figure 5. Create New Project with Project manager

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.

4.1.2 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.

Figure 10. Element added to New Workspace

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.

Figure 11. Element added to New Workspace

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.

4.1.3 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)

Figure 15. Label Element Properties for Application

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.

Figure 16. Label Element Positioning in the app View

Now, add connectors as shown below. The title label doesn’t need to be connected to anything since it just displays static text.

Figure 17. Application Element Connections

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).

Before launching any Build or Programming, please make sure to save first your project.
Select the Save button from the toolbar located in the top right corner to save your modifications

4.2.1 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.

Figure 1. Rapid IoT target specific SDKs

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.

Figure 2. KW41Z Target SDK Rapid IoT Apps

Figure 3. K64F Target SDK Rapid IoT Apps

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.

Figure 4. Rapid IoT Atmosphere Out of Box Application

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.

Figure 7. Rapid IoT non-Atmosphere middleware

The Hello World project is a default template to start any new Rapid IoT application

Let’s modify the hello_world.c code to control the RGB LED

The RGB LED, like every Rapid IoT components (including Application/K64F MCU peripherals), has been already configured and initialized

Right after the intialization of the LED, under the code below:


                            /* Init Led module */
                            LED_Init();

Add the following code to turn the LED blue, then white, then red during 1s each and turn it off.


                            RGB_Led_Set_State(RGB_LED_BRIGHT_HIGH, RGB_LED_COLOR_BLUE);
                            App_WaitMsec(1000);
                            RGB_Led_Set_State(RGB_LED_BRIGHT_HIGH, RGB_LED_COLOR_WHITE);
                            App_WaitMsec(1000);
                            RGB_Led_Set_State(RGB_LED_BRIGHT_HIGH, RGB_LED_COLOR_RED);
                            App_WaitMsec(1000);
                            RGB_Led_Set_State(RGB_LED_BRIGHT_OFF, RGB_LED_COLOR_WHITE);

Now let’s modify the hello_world.c code to display a simple message on the Rapid IoT screen
The display has been already configured and initialized in the Hello World project

Right after the intialization of the LED, under the code below:


                            /* Display a Message */
                            GUI_SetFont(&GUI_Font8x18);
                            GUI_SetBkColor(GUI_WHITE);
                            GUI_Clear();
                            GUI_SetColor(GUI_BLUE);
                            GUI_DispString("\n     Rapid IoT\n\n");

The application programmed in factory in the SLN-RPK-NODE supports both Bluetooth and Thread connectivity alternately. By default, Bluetooth radio is enabled so we must activate Thread from the application settings to connect SLN-RPK-NODE to the Gateway.

From the Welcome screen touch the Electrode T1 to open the Application screen.
Then touch the Electrode T2 to open the Settings screen.
Next touch the Electrode T1 to access the Bluetooth menu.
Finally touch the Electrode T2 to reach the Thread menu.

Now press the push button SW4 to activate Thread radio (and automatically disable Bluetooth radio).

After few seconds a message will confirm the selection and indicates that SLN-RPK-NODE must restarts to start Thread radio
Press the push button SW2 to restart the board

Figure 71. Access Thread on SLN-RPK-NODE

Open the Gateway Options by selecting the icon located in the top right corner

From the menu select End node commissioning

NFC Commissioning will be available in the next release
For now we will share the SLN-RPK-NODE MAC address manually with the Gateway

Select Thread and enter the SLN-RPK MAC address printed at the back of the SLN-RPK-NODE casing and press Submit

The phone App will display shortly a confirmation message that the SLN-RPK-NODE is successfully commissioned for Thread and open a new window with the instruction to connect each type of End Node supported by the Gateway (including the Rapid IoT board)

From the SLN-RKP-NODE Thread menu press the push button SW2 to join the Thread network. The White LED will start blinking quickly to confirm that SLN-RPK-NODE is trying to connect.

After few seconds the phone App will display a message to confirm that SLN-RPK-NODE joined successfully the Thread network and ask if we want to commission/connect another device.
Choose NO to display the list of the connected End nodes.

Select your Rapid IoT board from the list of the connected device thanks to its unique MAC address.

The phone App will display a new interface to monitor and control SLN-RPK-NODE sensors and actuators from the Cloud through Thread connectivity.
