+.. zephyr:code-sample:: stm32_ble_hr_802154_echo_client
+   :name: BLE HR - 802154 Echo client (advanced)
+
+   Implement a Bluetooth |reg| Energy Heart Rate - IEEE 802154 client.
+   The BLE Heart Rate (HR) GATT Service generates dummy heart-rate
+   values and the 802154 echo client sends IP packets, waits for data
+   to be sent back, and verifies it.
+
+Overview
+********
+
+The sample application implements a concurrent mode BLE - IEEE 802.15.4.
+Both wireless protocols Bluetooth |reg| Energy and IEEE 802.15.4 coexist:
+the application supports simultaneously one Bluetooth |reg| Energy connection
+and one IEEE 802.15.4 connection.
+The 802.15.4 part implements UDP client that will send IPv6 packets,
+wait for the data to be sent back, and then verify it matches
+the data that was sent.
+The BLE part exposes the HR (Heart Rate) GATT Service. Once a device
+connects, it will generate dummy heart-rate values.
+
+The source code for this sample application can be found at:
+:zephyr_file:`samples/boards/st/bluetooth/ble_hr_802154_echo_client`.
+
+The IEEE 802.15.4 config of the sample enables support for native
+IEEE 802.15.4 connectivity.
+Note that by default IEEE 802.15.4 L2 uses unacknowledged communication.
+To improve connection reliability, acknowledgments can be enabled with
+shell command: ``ieee802154 ack set``.
+
+Environment Setup
+*****************
+
+This sample has been tested on the STMicroelectonics NUCLEO-WBA65RI board
+(nucleo_wba65ri).
+This board interacts simultaneously with another board embedding an
+echo-server sample with the 802.15.4 overlay (nucleo_wba65ri) and a
+smartphone supporting BLE Heart Rate.
+
+Building and Running
+********************
+
+Build sample application like this:
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/boards/st/bluetooth/ble_hr_802154_echo_client
+   :board: nucleo_wba65ri
+   :goals: build
+   :compact:
+
+The LED 1 toggles while application is BLE advertising. Once a remote device
+connects, the LED 1 turns ON and application will generate dummy heart-rate values.
+Once remote device disconnects, the application restarts BLE advertising and LED 1
+toggles.
+
+Simultaneously, IEEE 802.15.4 feature is enabled. To validate behavior, use another
+board that will be used as a remote server.
+This can be done using echo-server sample application with :file:`overlay-802154.conf`.
+
+.. zephyr-app-commands::
+   :zephyr-app: samples/net/sockets/echo_server
+   :board: nucleo_wba65ri
+   :gen-args: -DEXTRA_CONF_FILE=overlay-802154.conf
+   :goals: build flash
+   :compact:
+
+Once both devices are connected, local device will send IPv6 packets, wait for
+the data to be sent back from the remote echo-server device, and then verify it
+matches the data that was sent.
