Yes, I have tried using nRF52840 as RCP with Raspberry Pi over native USB mode and that works fine. But in my custom hardware design I have CC2538 which is...

Sure, Initially we have tried, but I can try again with increased baudrate and share you the logs.

I have tried increasing the baudrate to 460800. But still the same behavior. Attached is the log [minicom_HighBoardRate_13Jan_1.txt](https://github.com/openthread/ot-br-posix/files/7861455/minicom_HighBoardRate_13Jan_1.txt)

Yes, but with 4-5 devices sending data at every 1 second, otbr-agent die quickly. I am not able to understand why is this happening? From the logs I have also...

Yes, we have validated UART with 115200 baudrate and it is working fine.

I haven't run my sample application with the 460800 baud rate. As this requires some hardware changes. I can try with that can update you. But, Are you really sure...

On RCP, OPENTHREAD_CONFIG_NCP_TX_BUFFER_SIZE is set to 8K. and RX buffer of otbr-agent is 30K.
