Introduction:

Amazon Sidewalk is a free, secure, low-power, and low-bandwidth network that connects devices to the internet. It uses Sidewalk Bridges, like compatible Amazon Echo and Ring devices, to provide cloud connectivity for IoT devices. Sidewalk can support long-range and low-bandwidth connectivity at home and beyond, using Bluetooth LE for short-distance communication and LoRa and FSK radio protocols at 900MHz frequencies for longer distances. Currently, Amazon Sidework can only be used in the United States. The use of Sidewalk gateway functions outside the United States is limited to the development and debugging of Amazon Sidework. Note that using Amazon Sidework outside the United States may violate local regulations.

 

Preparation:

1. AWS (Amazon Web Service) account (a credit card is required) is used as a cloud server

2. Amazon developer account is used to configure gateway devices using the app, $100 per month

3. Install AWS CLI aws command line tool

4. Gateway that supports Sidewalk

5. 52840dk + SX1262 development board or MinewSemi’s MS24SF1 module

6. NCS2.6.1; Environment configuration will not be explained here

7. Sidewalk code; This article uses version v2.6.1


 

Configuration:

Add device to AWS

Add Destinations

This step can also use the AWS CLI aws command line tool, which will not be introduced in detail here.

Log in to your AWS account and enter the Sidewalk configuration interface to add Destinations.

 


Add Sidewalk device

  • Click Provision device

 


  • Add device profile

 


Give it a name and click on Confirm

 


Click Next



Click Next

 


Click Create to configure successfully. The configuration is as follows:

Then download the Json file

 


The downloaded file is called certificate.json. Save it. This is used to configure the generated hex file.


Generate nordic_aws_nrf52840.hex

  • Open cmd in the path E:\ncs\ncs_v2.6.1\v2.6.1\sidewalk\tools\provision

According to the actual situation, my path is this

I have generated bin and hex files here


 

  • Copy certificate.json to this folder and enter the following commands to generate bin and hex reference link

 python provision.py nordic aws --output_bin mfg.bin --certificate_json certificate.json --addr 0xFF000

 


Sidewalk as a repository for ncs

Reference link

  •  Open command line



 

  • Enter the Sidewalk folder

At this time, some people may have questions about the v2.6.0-rc2 version. This is automatically switched to this path after west update.

Actually I downloaded version v2.6.1

 


In order to facilitate the description, I switch back to the V2.6 version here.

 


  • Make sure the manifest path points to west.yml in nrf, enter the following command

west manifest --path


 

  • If the manifest path points to a different file, use the following command to point to west.yml in nrf

west config manifest.path nrf

 

  • Enable Sidewalk group filter

west config manifest.group-filter “+sidewalk”

 


  • Check if Sidewalk exists

west list sidewalk

 

This already points to the V2.6.0-rc2 branch

 


  • Update repository

You can see branches switching directly here, no doubt about it

west update


 


  • Python requirements for installing Sidewalk

pip install -r sidewalk/requirements.txt

 

 

Setup to use internal flash upgrade

Since the process uses mcuboot and uses external flash upgrade, this will cause the module of MinewSemi to be unusable even if the pins are modified, so we first change it to internal flash upgrade here.

 

  • Delete the following configurations in boards/nrf52840dk_nrf52840.overlay and child_image/mcuboot/boards/boards/nrf52840dk_nrf52840.overlay

 


  • Modify configuration/nrf52840dk_nrf52840/pm_static_dfu.yml

    code show as below

 


  • Compile and burn

    Compiled memory allocation

 


  • Burning nordic_aws_nrf52840.hex

nrfjprog --sectorerase --program nordic_aws_nrf52840.hex --reset

 

 


  • Burning application

 


Since the Sidewalk gateway device has not been configured at this step, you can only display the following log, and there will be a sign that time synchronization failed.


 

I have a gateway device here, so I will add the following log later to show that the time synchronization is successful.


 

Configure Sidewalk Gateway

No more introduction here

 

Data Transmission

Short press button1 to send data to the server. The ble method is used by default.

 

Short press button3 to switch the data transmission mode to fsk

Short press again to switch to lora

 


Press button1 and send it to the server through lora

 


Modify Pin

If you do not use the dk board but use other boards (minewsemi ms24 series), you need to modify the pins

The modified overlay is as follows (boards/nrf52840dk_nrf52840.overlay)

 


But switching ble fsk and lora will cause errors

I have modified the dts here. I did not build the board myself. Just delete the red box part of nrf52840dk_nrf52840.dts.
