+/*!
+    \example heartlistener
+    \title Bluetooth Low Energy Heart Listener example
+
+    The Bluetooth Low Energy (BLE) Heart Listener Example shows how to develop a Bluetooth
+    Low Energy applications using the Qt Bluetooth API. The application covers
+    the scanning for BLE devices, connecting to the BLE Heart Rate service and
+    receiving updates from the BLE heart belt. The BLE heart belt is required
+    for this application to work.
+
+    \image heartrateintro.png
+
+    The best and the safest approach is to do a service discovery for BLE device first and
+    then pick the heart rate service. Before that it is necessary to connect signals from
+    the QLowEnergyController class, which is responsible for the communication with the
+    BLE device.
+
+    \snippet heartlistener/heartrate.cpp Connect signals
+
+    After service scan is done and heart rate service found, the heart rate measurement
+    characteristic needs to be found and enabled for the notifications (advertisements).
+
+    \snippet heartlistener/heartrate.cpp Connecting to service
+
+    The enableNotifications(m_heartRateCharacteristic) method is the one that
+    will enable advertisement from the BLE device. Every time, when new update gets from
+    the BLE device (in our case heart rate belt) QLowEnergyController will emit
+    valueChanged(QLowEnergyCharacteristicInfo) method, which will invoke
+    receiveMeasurement(const QLowEnergyCharacteristicInfo &) slot.
+
+    \snippet heartlistener/heartrate.cpp Reading value
+
+    Every BLE device has its own structure of data that is advertising. In the code above,
+    the approach for checking the value structure is presented. The heart rate service contains
+    that information in the first 8 bits of the advertised value. For instance, first bit tells
+    the format of the value (is it 8 or 16 bit value), fourth tells does the heart belt provide
+    energy spenditure information, etc.
+
+    \snippet heartlistener/heartrate.cpp Error handling
+
+    In case an error occurs, QLowEnergyController will emit error, which can be read with
+    errorString() method. An error for BLE service can occur in the process of connecting to
+    the service. For BLE characteristics, an error can occur when trying to subscribe for the
+    notifications.
+
+    In the end, it is required to disconnect from the service.
+
+    \snippet heartlistener/heartrate.cpp Disconnecting from service
