Installation

[35 min]

Workspace

• Install Arduino interactive desktop environment (IDE)

  • Navigate to the Arduino Desktop Download

  • Download the installation for your assocated operating system (Windows, macOS, or Linux)

  • Complete the installation instructions on the previous page

    • Accept agreement

      

    • Select local install only USER

      

    • Choose default install location under USER home

      

    • Choose Run Arduino after installation

    

    • The following screen will appear if installation is successful

    

Copy code repository

• Download a compressed ZIP of the code

  • Click the green CODE button at the top

  • Select Download ZIP

    

  • The default ZIP file will be downloaded to your ../USER/Downloads directory for both Windows or macOS

• Extract the ZIP by double clicking the file

  

  • The file will extract to the same directory ../USER/Downloads by default

    

  • Navigate to the extracted folder and open the ../src/ folder to find the open-iot-stem.ino program

    

  • Double click open-iot-stem.ino to open it in Arduino

    

  • You will then be prompted to import the sketch and create a project click OK

    

  • Select from the File>Save As from the title menu and save the project to your ../USER/../Ardunio/ directory this is the default location for all project

    

  • Confirm the location and save File>Save or press CTRL+S

    

• Post installation set-up

  • Update Boards

    We are using an Wisblock nRF52 for this training session you will need to add third party board support Arduino has built in board support for many boards but if you use others see third-party boards in they will be appended to this same location

    • Verify Arduino is open and use title menu to navigate to: File>Prefernces>Additional Board Support

      • Paste the following into the location and click OK to accept

      https://raw.githubusercontent.com/RAKwireless/RAKwireless-Arduino-BSP-Index/main/package_rakwireless_index.json

      https://raw.githubusercontent.com/RAKwireless/RAKwireless-Arduino-BSP-Index/main/package_rakwireless_com_rui_index.json

      • Open board manager Tools>Board>Boards Manager or CTRL+SHIFT+B

      

    • Search for RAK boards and install the following

      

    • After installation completes install the others

      

    • Select the board for your project Note: Wisblock RAK nRF board is shown as an example boards may vary based on your project

    

    

    • Save and quit the project to update boards File>Save CTRL+S and File>Quit CTRL+Q

      

  • Update libraries and dependancies

    • Open Arduino and sketch will auto load

    • Install libraries using links from code to automatically open Library manager

      • Scroll to the top of the code window in Arduino you will see the following

        

      • Hold down the key and click on each of the links to search for the library

        • AFter the library is found press INSTALL repeat until all libraries are installed

    •    ![notext](https://github.com/GrayHatGuy/open-iot-stem/blob/e1e39109b260238441e1cc3684ff06a48de22548/img/lib_bsec.png)  
      

    • Save and quit File>Save CTRL+S and File>Quit CTRL+Q

    • Open Arduino again to update changes

Edit code

[5 min] In order for the IoT device to be recognized within the LoRaWAN network you will need to add secret keys to the code these are similar to a username and password

• Edit code and to add LoRaWAN secrets and keys for the IoT

  • Navigate to the code window hold the CTRL key and press F to search the code

  • Type 'deviceEUI' to locate the secrets that require updating

  • Update the 00000s in the code to reflect the secrets for your IoT device

    

  • Save the sketch File>Save CTRL+S

Compile and build code

[5 min] To run the code we need to verify the code for errors and check that all necessary libraries and components are installed this is referred as building and/or compiling

• Click the Verify button to compile and build code

  

• You will see the following if the code has succesffully been Verified

  

Flash code

After the code has completed a successful build/compile we need to upload the program and flash the iot device with the code

• Verify USB is connected to IoT

• Check that correct board and port is selected

  

• Select the Upload button to flash program the device

  

• The terminal window at the bottom of the screen will update with the Upload results

• The device will automatically start when flash is complete

Verification

[10 min]

• Open the serial monitor using the menu title bar Tools>Serial Monitor or pressing CTRL+SHIFT+M keys

• The serial monitor will show the sensor information below the code window
