SDK3.0.2 - Unable to connect to OTBR

RE: SDK3.0.2 - Unable to connect to OTBR

Thanks. I could make my devices communicate with OTBR while using SDK3.0.2.
But still mixing of devices from SDK2.4.1 and SDK3.0.2 may cause problem. So, I am not mixing and simply upgrading devices to 3.0.2 only.

We can close this ticket for now. Once I have some more progress, will update.

Regards

Arun

Hi,

I will also help with this ticket.

Is this the first time you have updated the devices, or have you upgraded version before?
How do you upgrade the devices? OTA or a Programmer? If you use OTA, which protocol do you OTA over?
Do the 2.4.1 devices still work?
Can you read out (and not share) channel, panid and networkkey for both v2.4.1 and v3.0.2 devices and compare these?

Sigurd Hellesvik

Hi Arun,
I don't seem to have access to the files. Could you zip and upload them here?

Thanks,
Benjamin

Dear Benjamin,

I have added journel entry file copies at my drive https://drive.google.com/drive/folders/1pugeX9FLmxm-EcYY2yJXic2NxNopnOcj?usp=sharing

These are 2 days old - 16th Feb when

a) Initially 2.4.1 devices were connected b) Then I could connect 3.0.2 devices c) Then when I merged 2.4.1 and 3.0.2 - everything failed and then 3.0.2 devices were permanently thrown out.

Added one Note-Pad journel entries of today - 18-Feb. Here I connected only 1 3.0.2 device to OTBR which was earlier running with couple of 2.4.1 devices and tried to form the network.

Hope you can read these and help me..

Regards

Arun

Hi Arun,

Could you please share the device logs and OTBR logs captured when the issue occurs? Please include journalctl -u otbr-agent starting from when the service was started.

Best regards,
Benjamin
