Gerard Marull-Paretas 79e6b0e0f6 includes: prefer <zephyr/kernel.h> over <zephyr/zephyr.h>
As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.

The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.

NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

Bluetooth: ST BLE Sensor Demo
#############################

Overview
********

This application demonstrates BLE peripheral by exposing vendor-specific
GATT services. Currently only button notification and LED service are
implemented. Other BLE sensor services can easily be added.
See `BlueST protocol`_ document for details of how to add a new service.

Requirements
************

* `ST BLE Sensor Android app <ST BLE Sensor app>`_
* A board with BLE support

Building and Running
********************

This sample can be found under :zephyr_file:`samples/bluetooth/st_ble_sensor` in the
Zephyr tree.

Open ST BLE Sensor app and click on "CONNECT TO A DEVICE" button to scan BLE devices.
To connect click on the device shown in the Device List.
After connected, tap LED image on Android to test LED service.
Push SW0 button on embedded device to test button service.

See :ref:`bluetooth samples section <bluetooth-samples>` for details.
