+    
+    **Next\* (Error | Completed)?**
+    
+    * sequences can produce zero or more elements so zero or more `Next` events can be sent to `observer`
+    * once an `Error` or `Completed` event is sent, the sequence terminates and can't produce any other elements
+    
+    It is possible that events are sent from different threads, but no two events can be sent concurrently to
+    `observer`.
+    
+    ### Resource Management
+    
+    When sequence sends `Complete` or `Error` event all internal resources that compute sequence elements
+    will be freed.
+    
+    To cancel production of sequence elements and free resources immediately, call `dispose` on returned
+    subscription.
+    
+    - returns: Subscription for `observer` that can be used to cancel production of sequence elements and free resources.

-/// implemented by `RxCBCentralManager` and should not be used directly by the user of a RxBluetoothKit library.
-/// You can start using this class by discovering available services of nearby peripherals. Before calling any
-/// public `BluetoothManager`'s functions you should make sure that Bluetooth is turned on and powered on. It can be done
-/// by calling and observing returned value of `monitorState()` and then chaining it with `scanForPeripherals(_:options:)`:
-/// ```
-/// bluetoothManager.rx_state
-///     .filter { $0 == .PoweredOn }
-///     .take(1)
-///     .flatMap { manager.scanForPeripherals(nil) }
-/// ```
-/// As a result you will receive `ScannedPeripheral` which contains `Peripheral` object, `AdvertisementData` and
-/// peripheral's RSSI registered during discovery. You can then `connectToPeripheral(_:options:)` and do other operations.

-    ### Grammar
-    
-    **Next\* (Error | Completed)?**
-    
-    * sequences can produce zero or more elements so zero or more `Next` events can be sent to `observer`
-    * once an `Error` or `Completed` event is sent, the sequence terminates and can't produce any other elements
-    
-    It is possible that events are sent from different threads, but no two events can be sent concurrently to
-    `observer`.
-    
-    ### Resource Management
-    
-    When sequence sends `Complete` or `Error` event all internal resources that compute sequence elements
-    will be freed.
-    
-    To cancel production of sequence elements and free resources immediately, call `dispose` on returned
-    subscription.
-    
-    - returns: Subscription for `observer` that can be used to cancel production of sequence elements and free resources.

-    
-    **Next\* (Error | Completed)?**
-    
-    * sequences can produce zero or more elements so zero or more `Next` events can be sent to `observer`
-    * once an `Error` or `Completed` event is sent, the sequence terminates and can't produce any other elements
-    
-    It is possible that events are sent from different threads, but no two events can be sent concurrently to
-    `observer`.
-    
-    ### Resource Management
-    
-    When sequence sends `Complete` or `Error` event all internal resources that compute sequence elements
-    will be freed.
-    
-    To cancel production of sequence elements and free resources immediately, call `dispose` on returned
-    subscription.
-    
-    - returns: Subscription for `observer` that can be used to cancel production of sequence elements and free resources.

-  // only changes the dimensions of elements in that pair. This is key to understanding
-  // how the following functions operate, since each function is bound to a pair.
-  //
-  // A pair object is shaped like this:
-  //

-  //     isLast: Boolean,
-  //     direction: 'horizontal' | 'vertical'
-  // }
-  //
-  // The basic sequence:
-  //
-  // 1. Set defaults to something sane. `options` doesn't have to be passed at all.
-  // 2. Initialize a bunch of strings based on the direction we're splitting.
-  //    A lot of the behavior in the rest of the library is paramatized down to
-  //    rely on CSS strings and classes.
-  // 3. Define the dragging helper functions, and a few helpers to go with them.
-  // 4. Loop through the elements while pairing them off. Every pair gets an
-  //    `pair` object, a gutter, and special isFirst/isLast properties.
-  // 5. Actually size the pair elements, insert gutters and attach event listeners.

-</p>
-<p>This guide is an introduction to BLE stack and APIs exported by this library. All examples
-will be based on CC2541 SensorTag.</p>
-<h2>Creating BLE Manager</h2>
-<p>First step is to create BleManager instance which is an entry point to all available APIs.
-Make sure to create it after application started its execution. For example we can do it in
-Component's constructor:</p>
-<pre class='hljs'><span class="hljs-keyword">import</span> { BleManager } <span class="hljs-keyword">from</span> <span class="hljs-string">'react-native-ble-plx'</span>;
-
-<span class="hljs-keyword">constructor</span>() {
-    <span class="hljs-keyword">super</span>();
-    <span class="hljs-keyword">this</span>.manager = <span class="hljs-keyword">new</span> BleManager();
-    ...
-}</pre>
-<p>Only one instance of BleManager is allowed. When you don't need any BLE functionality you
-can destroy created instance by calling <code>this.manager.destroy()</code> function. You can then
-recreate <code>BleManager</code> later on as we did above.</p>
-<h2>Waiting for Powered On state</h2>
-<p>When iOS application launches BLE stack is not immediately available and we need to check its status.
-To detect current state and following state changes we can use <code>onStateChange()</code> function:</p>
-<pre class='hljs'>componentWillMount() {
-    <span class="hljs-keyword">const</span> subscription = <span class="hljs-keyword">this</span>.manager.onStateChange(<span class="hljs-function">(<span class="hljs-params">state</span>) =&gt;</span> {
-        <span class="hljs-keyword">if</span> (state === <span class="hljs-string">'PoweredOn'</span>) {
-            <span class="hljs-keyword">this</span>.scanAndConnect();
-            subscription.remove();
-        }
-    }, <span class="hljs-literal">true</span>);
-}</pre>
-<h2>Scanning devices</h2>
-<p>Devices needs to be scanned first to be able to connect to them. There is a simple function
-which allows only one callback to be registered to handle detected devices:</p>
-<pre class='hljs'>scanAndConnect() {
-    <span class="hljs-keyword">this</span>.manager.startDeviceScan(<span class="hljs-literal">null</span>, <span class="hljs-literal">null</span>, (error, device) =&gt; {
-        <span class="hljs-keyword">if</span> (error) {
-            <span class="hljs-comment">// Handle error (scanning will be stopped automatically)</span>
-            <span class="hljs-keyword">return</span>
-        }
-
-        <span class="hljs-comment">// Check if it is a device you are looking for based on advertisement data</span>
-        <span class="hljs-comment">// or other criteria.</span>
-        <span class="hljs-keyword">if</span> (device.name === <span class="hljs-string">'TI BLE Sensor Tag'</span> || 
-            device.name === <span class="hljs-string">'SensorTag'</span>) {
-            
-            <span class="hljs-comment">// Stop scanning as it's not necessary if you are scanning for one device.</span>
-            <span class="hljs-keyword">this</span>.manager.stopDeviceScan();
-
-            <span class="hljs-comment">// Proceed with connection.</span>
-        }
-    });
-}</pre>
-<p>It is worth to note that scanning function may emit one device multiple times. However
-when device is connected it won't broadcast and needs to be disconnected from central
-to be scanned again. Only one scanning listener can be registered.</p>
-<h2>Connecting and discovering services and characteristics</h2>
-<p>Once device is scanned it is in disconnected state. We need to connect to it and discover
-all services and characteristics it contains. Services may be understood
-as containers grouping characteristics based on their meaning. Characteristic is a
-container for a value which can be read, written and monitored based on available
-capabilities. For example connection may look like this:</p>
-<pre class='hljs'>device.connect()
-    .then(<span class="hljs-function">(<span class="hljs-params">device</span>) =&gt;</span> {
-        <span class="hljs-keyword">return</span> device.discoverAllServicesAndCharacteristics()
-    })
-    .then(<span class="hljs-function">(<span class="hljs-params">device</span>) =&gt;</span> {
-       <span class="hljs-comment">// Do work on device with services and characteristics</span>
-    })
-    .catch(<span class="hljs-function">(<span class="hljs-params">error</span>) =&gt;</span> {
-        <span class="hljs-comment">// Handle errors</span>
-    });</pre>
-<p>Discovery of services and characteristics is required to be executed only once. Additionally
-it can be a long process depending on number of characteristics and services available.</p>
-<h2>Read, write and monitor values</h2>
-<p>After successful discovery of services you can call </p>
-<ul>
-<li><a href="#blemanagerreadcharacteristicfordevice">BleManager.readCharacteristicForDevice()</a>,</li>
-<li><a href="#blemanagerwritecharacteristicwithresponsefordevice">BleManager.writeCharacteristicWithResponseForDevice()</a>, </li>
-<li><a href="#blemanagermonitorcharacteristicfordevice">BleManager.monitorCharacteristicForDevice()</a></li>
-</ul>
-<p>and other functions which are described in detail in documentation.</p>
