Hi,

[quote user="ArunRuchir"]<Arun> 2.4.1[/quote]

Could you try the latest NCS, v2.7.0?

[quote user="ArunRuchir"]Please suggest how to check if DK is properly flashed with RCP and why it is not working with RP4 as OTBR. [/quote]

The Thread: Co-processor sample supports optional logging extension, which can be turned on or off independently. See Snippets for details. Please provide the log to help investigate the issue.

Are you using Thread: Co-processor for nRF52840 Dongle?

<Arun> I had an 7-8 months old Hex file which I am successfully using. I have not tried new flashing for now.

Which version of NCS are you using?

<Arun> 2.4.1

Please elaborate on how it doesn't work as RCP. Any log? You can build with snippets logging to get the RTT log.

<Arun> My RP4 with Dongle is working fine as OTBR. Once I flash DK with Co-Processor and connect to RP4, it does not work as OTBR. No logs or any visible feedback.

Also, please check and configure the following library option that is used by the sample:

CONFIG_OPENTHREAD_COPROCESSOR_RCP - Selects the RCP architecture for the sample.
<Arun> Yes, this is part of Prj file while compiling.

Please suggest how to check if DK is properly flashed with RCP and why it is not working with RP4 as OTBR.
My ultimate objective is to use my customer nRF52840 module as RCP (which will happen once DK is working fine).

Regards

Arun

[quote user=""]I have compiled sample/openthread/coprocessor as RCP using VS-Code. When trying the same via 52840DK or my custom nRF52840 modules, its not working as RCP. [/quote]
