to get to know which commmand does host is sending and event getting from controller

[Shreeyash17]

 Can you please help to suggest how to get hci logs in channel sounding examples?
Like my use case is that I want to know which commands are going from host to controller and which events does host is getting from the controller.
For example, from ogf and ocf I will get to know what is exactly happening.
I have tried by enabling  CONFIG_BT_CS_DE_LOG_LEVEL_DBG, but I got logs like below.​

Hi, 

Check out the HCI Tracing and Capturing HCI packets documentation.

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.
