Hi,

Try to use the HCI USB sample instead.

Then use the "nRF USB" connector to connect after flashing the DK.

Hy sigurd ,

thank you for the replay 

i tried hci_usb also 

steps i followed 

1. building the hci_usb in the git bash 

2.flashing the hci_usb

3. then i connected the board to the linux laptop 

here i use the commands

a. treminal 1 . btmon

b .terminal 2 . sudo btattach -B /dev/ttyACM0 -S 115200 -P h4 

c. terminal 3 .sudo btmgnt -i 1

    [hci1]# auto-power
Found controller with index 1

in my btmon screen i am able to see that status as success 

can you conform this process is correct?

But when i tried to do btattach .its shows this in the btmon
