RAK4631 WisBlock LPWAN Module Amazon Sidewalk Starter Kit

The Sidewalk Starter Kit simplifies the setup and testing of a RAKwireless device with Amazon Sidewalk. It comes with all of the necessary hardware, including a temperature and humidity sensor. There are also tools for flashing the Amazon Sidewalk firmware onto the device.

Amazon Sidewalk is a free-to-connect community network that provides secure and reliable connectivity for billions of devices. The Sidewalk Starter Kit is based on the WisBlock Core RAK4631, which incorporates the WisDuo RAK4630 Stamp Module. Furthermore, Amazon has certified the RAK4630 as a Sidewalk-compatible device, implying that it can be used to easily build Sidewalk devices.

The WisBlock modules in the kit eliminate the need for a prototype board. Just plug the modules together and power them via a USB port or another power source.

NOTE

Amazon Sidewalk is only available in selected areas in the USA, including the testing or use of a Sidewalk device. Check out the coverage map at Amazon Sidewalk Coverage.

For development, any Sidewalk gateway functionality might be used outside of the US, but it should be used ONLY for Amazon Sidewalk endpoint development purposes. Developers are solely responsible for ensuring compliance with local regulations. Please consult with your local regulatory bodies and check if the gateway is allowed to operate its radio in your locale, as US license-free band devices, only for development. Developers will also need to use a VPN router that supports OpenVPN Client functionality in conjunction with a cloud VPN service provider, to enable operation outside of the US for your development.

NOTE

To connect the device to the Sidewalk network, an Amazon Sidewalk compatible device is required. Check the Amazon Sidewalk Documentation for more information.

Quick Start Guide

This guide will help you test a RAK4630-based device with Amazon Sidewalk, including sensor data visualization in AWS. It offers fast access to connect the RAK4630 to Amazon Sidewalk. Also, it comes with pre-compiled firmware that you can flash on our WisBlock Core module.

The application used in this guide is based on the Nordics Sidewalk Sensor Monitoring example code. Then, the code was modified to work with the WisBlock Core module (nRF52840 + SX1262 LoRa transceiver) and the RAK1901 temperature and humidity sensor.

For details about the Sidewalk application for RAK4630, refer to RAK4630-Amazon-Sidewalk-Example repo.

Device Setup

NOTE

Flash the Sidewalk Starter Kit with the example firmware and device credentials.

Connect the Sidewalk Starter Kit and the RAKDAP1 Device

The RAKDAP1 device is used to flash firmware and provision keys to the RAK4630 module. The programming pins of the WisBlock RAK4631 Core module are exposed on one side. The following is the link between the RAKDAP1 and the RAK4631:

Zoomable
Figure 1: RAK4630 and RAKDAP1 Connection

The WisBlock modules must be powered by a battery or via a USB connector to avoid problems during the process.

Install the Required Software Tools

Python 3 Installation

RAKDAP1 requires a Python 3 installation before it can be used. Download the latest Python 3 from the official Python website. Go to their Python Downloads page (opens a new window) and select an installer based on your system.

Windows
  1. Choose the Python installer for Windows.
  2. Once downloaded, start the installation process.
  3. Make sure to check the Add python.exe to PATH. Otherwise, you will have to add it manually later.
Zoomable
Figure 1: Python Installation
  1. Wait until the installation is finished.
Zoomable
Figure 1: Python Installation
  1. After the installation is complete, open the command prompt window. Use the following command to verify the versions of Python and pip3:
python --version
pip --version
NOTE

pip3 is required to install additional Python packages.

macOS

Open the terminal on your Mac machine and type the following commands:

ruby -e $(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)
export PATH="/usr/local/opt/python/libexec/bin:$PATH"
NOTE

If your macOS is based on Apple M chips, you might need to use this path:

export PATH="/opt/homebrew/opt/python/libexec/bin:$PATH" or export PATH="/opt/homebrew/opt/python@3/libexec/bin:$PATH"
brew install python
python --version
brew install libusb

After the installation has finished, open a command prompt window. Check the versions of Python and pip3 using the following command listed below.

python --version
pip --version
Linux

Open the terminal on your Linux machine and type the following command: sudo apt-get install python3

After the installation has finished, open a command prompt window. Check the versions of Python and pip3 using the following command listed below:

python --version
pip --version
pyOCD Installation

The next step is to install pyOCD, the software tool required for flashing bootloaders and application software.

  1. To start the installation, open the command prompt and use the following command:
pip3 install pyocd
  1. After the installation is finished, verify the version.
pyocd --version
Support Packages Installation

To flash and debug MCU, DAPLink needs support packages. These support packages are MDK files. For more details, you can refer to the supporting list of MDK.

  1. To install the support package, use the following command:
pyocd pack --i <PACKAGE>
  1. For the Sidewalk Starter Kit, install the MDK for the RAK4630 module. Enter the following command:
pyocd pack --i nrf52840
  1. To check installed packages, you can use the command:
pyocd pack -s

Before flashing a new firmware, you can also perform the erase command.

warning

Erasing the flash memory will remove the current flashed firmware, and it will also erase the device provisioning information.

pyocd erase -t nrf52840 --chip

Flash Example Firmware and Device Credentials with RAKDAP1

The RAK4630 in the Sidewalk Starter Kit is already flashed with the right firmware. However, it cannot connect to the Sidewalk network without the correct provisioning key that you created in the previous step.

  1. To flash the provisioning key, use RAKDAP1 adapter and run the following command to flash the HEX file you created.
NOTE

You must be in the directory or location where the hex files are located before proceeding with flashing. Otherwise, the process will not proceed.

pyocd flash -t nrf52840 YOUR_PROVISIONING_KEY.hex
  1. Disconnect the RAKDAP1 adapter, connect a terminal application, and reset the starter kit to check if the application is starting normally.

  2. If you have replaced the original firmware of the RAK4630 with a custom firmware, you have to flash the provisioning key every time AFTER you flash a custom firmware.

pyocd flash -t nrf52840 YOUR_CUSTOM_FIRMWARE.hex
pyocd flash -t nrf52840 YOUR_PROVISIONING_KEY.hex
  1. After flashing the Sidewalk Starter Kit, disconnect both the kit and the RAKDAP1 tool from power and from each other.
  2. Then power up the Sidewalk Starter Kit through its USB connector.

If the device is in range of an Amazon ECHO Gen4 (or another Sidewalk compatible Amazon device), it will automatically connect to Sidewalk and send the sensor's measured data to AWS.

IMPORTANT
  • A device profile created for prototyping through the AWS console can only be used with one device.
  • A device profile created for manufacturing and linked with HSM applies to all products of that product type. However, if you have four different products (Sensor A, B, C, and D), you will need to load four different device profiles onto your HSM.
  • A provisioning key is for a single device, and each device needs its own unique key.

After flashing the firmware, the device should be powered up. You can view the device log output by opening a Serial Terminal application on your computer. If you encounter error messages, it is likely due to one of the following reasons:

  • missing provisioning key
  • incorrect provisioning key or device profile
  • no Sidewalk device in range

Firmware Source Code

The source code for the RAK4631 Sidewalk Starter Kit is available as open source on Github: RAK4630-Amazon-Sidewalk-Example repo.

To install the necessary development tools, refer to the installation guides available in the Amazon Sidewalk Documentation.
