Sidewalk device registration failed

[666]

When the situation shown in the above figure occurs, I want to test the functionality of Sidewalk. Is there any simplest way to test it? Currently, only nrf52840dk is available

Hi all，

After performing the following actions, it showed that there was no registration.

Then, I downloaded the Alexa app, started Sidewalk, and connected Echo to WiFi. Then I pressed boot/reset again, but the result still showed that there was no registration. I don't know which step was missing.No modifications have been made using the default sid_end_device.

Looking forward to your reply.

Thanks,

The red part is the content of nrf52840dk that I read out, which proves that "nrfjprog -- sectorerase -- program nordic.aws_nrf52840.hex -- reset“this step was successful, and then NRF Connect was able to scan the beacon, which proves that the device is functioning properly.

This is the packet capture of the echo gateway.

However, we don't know where to look for the cause.

Looking forward to your reply.

Thanks,

Hello,

I apologize for the delay in my response; I was away for the past two days attending some workshops.

From the logs and details you’ve provided,your device is not registering with the Amazon Sidewalk network, and there’s a time synchronization failure. The link statuses for BLE, FSK, and LoRa are showing as "Down", which indicates that the device has not yet established communication properly with the Sidewalk network. Have you followed all the steps mentioned under setting up your Sidewalk Gateway and Setting up your sidewalk product. 

From the image, provisioning step using provision.py and nrfjprog, looks successful. Ensure that the certificate.json used is valid and correct for your setup.

Kind Regards,

Abhijith

1."setting up your Sidewalk Gateway"For this, since I am using the echo gateway, I did not perform the following operations. I am not sure if it will have any impact.

This is my operation（Setting up a Sidewalk gateway (Optional) | Amazon Sidewalk Documentation）

2." Setting up your sidewalk product"I am using the operation of v2.6.0(Setting up your Sidewalk product (nordicsemi.com)). I am not sure if it will have any impact

3.I can see that the data of ble beacon contains the first 10 characters of smsn in certificate. json

Hello,

Could this be an issue with your location or network? Are you using a US-based VPN for testing the sample? Sidewalk requires a US network to function. Apologies if you're already doing this just trying to clarify so we can narrow down the root cause.
