SDK3.0.2 - Unable to connect to OTBR

Hi,
I have upgraded my custom nRF52840 devices from SDK 2.4.1 to SDK 3.0.2. For few days, these devices did connect to existing OpenThread network. But now, all SDK3.0.2 devices are not able to communicate with OTBR. Ping from OTBR to device IP is also not working. No communication on UDP is coming.

We also tried upgrading RCP but no benefit.

RCP version
OPENTHREAD/thread-reference-20230119-531-g8ea2031c7; POSIX; Jul 25 2023 20:05:36

We will have mix devices - SDK 2.4.1 and SDK3.0.2 both on the network. If we remove all 2.4.1 devices, then complete network gets crashed.

Please help get 3.0.2 devices also communicate with OTBR.

Regards

Arun

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.
