Hello Amanda Hsieh ,
Thank you for the response.

The thing is that I have seen the solutions you have provided but HCI Tracing is for the case when I am using nrf board only as a controller, or if there is any UART communication is happening, and Capturing HCI packets is used to capture over the air packets.

My intention is to capture the commands sent from host to controller and events received from controller to host while running channel sounding sample, and in this case, both host and controller are present on the nRF board.

So, how to capture commands and events if both the host and the controller are in nrf board?

please help me with this.

Hi,

Check out the HCI Tracing and Capturing HCI packets documentation.
