+               <li>the advertiser mode is set to <span style="font-family: Courier New,Courier,monospace">BT_ADAPTER_LE_ADVERTISING_MODE_LOW_LATENCY</span> which sets the lowest possible
+               interval between subsequent packets sending with the cost of higher energy consumption (<span style="font-family: Courier New,Courier,monospace">bt_common_set_advertising_mode()</span>);</li>
+               <li>the advertiser remains connectable by other peers (<span style="font-family: Courier New,Courier,monospace">bt_common_set_connectable()</span>);</li>
+               <li>the advertiser's properties are defined and set:
+                       <ul>
+                               <li>for advertising mode (<span style="font-family: Courier New,Courier,monospace">__set_advertizing_properties()</span>);</li>

+The advertiser's properties setting determines the amount and the category of information to be broadcasted over the Bluetooth LE adapter. It is assumed that:
+       <ul>
+               <li>
+               an advertising packet (<span style="font-family: Courier New,Courier,monospace">BT_ADAPTER_LE_PACKET_ADVERTISING</span>) is a carrier of the following information:
+                       <ul>
+                               <li>device's name (obtained automatically by the internal implementation of the Bluetooth LE Adapter module);</li>
+                               <li>manufacturer's identifier: 0x0075 (complies with the <a href="https://www.bluetooth.com/specifications/assigned-numbers/Company-Identifiers">company identifiers</a>
+                               assigned by the Bluetooth SIG, Inc.). The assigned value identifies Samsung Electronics Co. Ltd. company.</li>
+                       </ul>
+               The role of this type of packet is to introduce the device (advertise its existence) within the Bluetooth LE network. The one who receives such a packet can send a scan request to query detailed data
+               carried by the device.
+               </li>
+               <li>
+               a scan response packet (<span style="font-family: Courier New,Courier,monospace">BT_ADAPTER_LE_PACKET_SCAN_RESPONSE</span>) is a carrier of the following information:
+                       <ul>
+                               <li>device's name (obtained automatically by the internal implementation of the Bluetooth LE Adapter module);</li>
+                               <li>appearance: 832 (complies with the
+                               <a href="https://developer.bluetooth.org/gatt/characteristics/Pages/CharacteristicViewer.aspx?u=org.bluetooth.characteristic.gap.appearance.xml">external device's appearance</a>
+                               assigned by the Bluetooth SIG, Inc.). The assigned value identifies the device as a Generic Heart Rate Sensor.</li>
+                               <li>manufacturer's identifier (see the itemization above for details).</li>
+                       </ul>
+               The role of this type of packet is to provide detailed data acquired during the service lifecycle (heart rate measuremet and body sensor location values). This packet is sent in response to a scan request.
+               </li>
+       </ul>
+The <span style="font-family: Courier New,Courier,monospace">__set_advertizing_properties()</span> and the
+<span style="font-family: Courier New,Courier,monospace">__set_scan_response_properties()</span> functions are only convenient wrappers and call the
