Capture the HCI Messages using btmon via rpmsg

Would like to capture the HCI flow through rpmsg (Rx and TX) using the btmon tool between application and network core. could not successfully do it.

Procedure:

1. Build and flashed the samples\bluetooth\hci_rpmsg on Network Core

2. Build and flashed the samples\bluetooth\peripheral on Application Core

Jumper are connected as per the document

Have been following the video : https://www.youtube.com/watch?v=uqKxmsrP2Hc

Could not get the HCI flow between the Application core and Network core. Do we need to enable or disable any configuration during build. Please help.

Hi,

In the peripheral prj.conf, add these configs:

CONFIG_BT_DEBUG_MONITOR=y
CONFIG_UART_CONSOLE=n

Then you open the serial port via this command (you want the third com port of the DK, might be different on your PC):

btmon --tty /dev/ttyACM2 --tty-speed 115200

And you should see this output:
