Hi!
I'm interested in trying out hci_usb sample of nRF Connect SDK with Nordic's Link Layer.
With following changes to application configuration I'm able to compile the hci_usb sample:
diff --git a/samples/bluetooth/hci_usb/prj.conf b/samples/bluetooth/hci_usb/prj.conf index 1c19e32540..2ccd19c2a4 100644 --- a/samples/bluetooth/hci_usb/prj.conf +++ b/samples/bluetooth/hci_usb/prj.conf @@ -9,3 +9,6 @@ CONFIG_BT_HCI_RAW=y CONFIG_USB=y CONFIG_USB_DEVICE_STACK=y CONFIG_USB_DEVICE_BLUETOOTH=y + +CONFIG_BT_LL_NRFXLIB=y +CONFIG_BT_MAX_CONN=10
When trying to use nRF52840 DK as a Bluetooth LE dongle in Linux there seems to be some problems in initialization. See the btmon trace below.

I'm using commit 169ed14ee2371073e63d922733345dbcad2a5218 of fw-nrfconnect-nrf.
Steps to reproduce:
1. cd ncs/zephyr/samples/bluetooth/hci_usb
2. apply the diff above to prj.conf
3. west build -b nrf52840_pca10056 && west flash
4. start btmon
5. reset the board and check the btmon log.
