+
+nRF91x1: DECT NR+ PHY hello sample
+##################################
+
+.. contents::
+   :local:
+   :depth: 2
+
+This sample demonstrates how to set up a simple DECT NR+ application with the DECT PHY modem firmware.
+
+.. important::
+
+   DECT NR+ operates on free but regulated radio channels. The regulation and availability of the channels varies in different countries.
+   It is the responsibility of the developer to operate the devices according to the local regulation, both at the development site and the device operation regions.
+
+Requirements
+************
+
+The sample needs at least two nRF91x1 Development Kits.
+
+See :ref:`nrf91x1_ug_intro` for more details.
+
+.. note::
+
+   The :ref:`nrf_modem_dect_phy_simple` require a special modem firmware to run on the nRF91x1 modem core. Please contact our sales department to know more.
+
+
+.. include:: /includes/tfm.txt
+
+Overview
+********
+
+The sample shows a simple broadcast and reception of DECT NR+ messages between devices on a hard-coded channel.
+
+After initialization the devices will run a loop, transmitting a counter value before listening for incoming receptions for :kconfig:option:`CONFIG_RX_PERIOD_S`.
+The loop is exited after a number of transmissions given by the :kconfig:option:`CONFIG_TX_TRANSMISSIONS` Kconfig option, or continue forever if the :kconfig:option:`CONFIG_TX_TRANSMISSIONS` Kconfig option is ``0``.
+
+Each device can be reset to run the sample again.
+
+Building and running
+********************
+
+.. |sample path| replace:: :file:`samples/modem_trace_flash`
+
+.. include:: /includes/build_and_run_ns.txt
+
+..note::
+
+   You need to configure the sample in accordance to local regulations. If you are in the EU and US, you can use the ``overlay-eu.conf`` and ``overlay-us.conf``Kconfig overlays respectively.
+
+Testing
+=======
+
+|test_sample|
+
+After programming the sample to your development kits, test it by performing the following steps:
+
+#. |connect_kit|
+#. |connect_terminal|
+#. Observe that the devices will transmit a counter value that is received by the other devices.
+#. After a given number of transmissions, observe that the devices shut down and exit the sample.
+
