To run the application on nRF5340DK there must be provided a child image aimed to
run on network core. :zephyr_file:`samples/bluetooth/hci_rpmsg` sample application
may be used for that purpose.
To build :zephyr_file:`samples/bluetooth/hci_rpmsg` sample with direction finding
support enabled:
* create :zephyr_file:`samples/bluetooth/hci_rpmsg/boards/nrf5340dk_nrf5340_cpunet.overlay`with the same content as
:zephyr_file:`samples/bluetooth/direction_finding_connectionless_rx/boards/nrf52833dk_nrf52833.overlay`
* create :zephyr_file:`samples/bluetooth/hci_rpmsg/boards/nrf5340dk_nrf5340_cpunet.conf`
file. Copy content of
:zephyr_file:`samples/bluetooth/direction_finding_connectionless_rx/boards/nrf52833dk_nrf52833.conf.
Add CONFIG_BT_EXT_ADV=y configuration entry to enable extended size of
:code:`CONFIG_BT_BUF_CMD_TX_SIZE` config to support LE Set Extended Advertising Data command.

Antenna matrix configuration for nRF5340DK SOC is part of child image that is run
on network core. When :zephyr_file:`samples/bluetooth/hci_rpmsg` is used as network
core application, the antenna matrix configuration is stored in the :zephyr_file:`samples/

Antenna patterns

The antenna switching pattern is a binary number where each bit is applied to a particular antenna
