The Bluetooth communication of intelligence receiving end is a most important ring in whole receiving system, and Bluetooth communication is broadly divided into be opened bluetooth, obtain bluetooth, connects bluetooth, data and transmit four parts.Carry out to tell about in detail this Four processes below:
(1) bluetooth is opened
The experience mode opening bluetooth has two kinds, and the first jumps out dialog box inquiry user whether to open bluetooth when opening application, and user selects "Yes" to open bluetooth, otherwise does not open bluetooth.Also have a kind of mode to be directly open bluetooth, do not eject selection dialog box when namely opening application program, directly open bluetooth.In these two kinds of modes, need the class used to be BluetoothAdapter, for class BluetoothAdapter, be exactly the Bluetooth adapter of this equipment simply.By creating BluetoothAdapter object, utilizing the enable () of this object, disable () method completes opening and closedown local bluetooth device.Wherein isEnabled () method is for judging whether bluetooth is opened, and bluetooth is opened in the effect of enable () method.If we also need to use disable () method to want to close bluetooth.At intelligent receiving end of the present invention, we select the experience mode opening bluetooth to be the second, namely do not need reminding user, directly open bluetooth equipment.Embodiment is: in the class SensorActivity.java created, create a BluetoothAdapter object be named as mBluetoothAdapter, the isEnabled () method calling this object in onStart () method judges whether bluetooth is opened, if do not open, calls enable () method and opens bluetooth.
(2) bluetooth is obtained
Because have the bluetooth discovery program carried in the setting options of every portion mobile phone, so the volume in order to reduce application, this part function can not be embodied in our application.The bluetooth equipment that this intelligent receiving end obtains is the local equipment matched.The main class used at this is still BluetoothAdapter, and the method used has getDefaultAdapter (), getBondedDevices (), getName (), getAddress () etc.Wherein the effect of method getDefaultAdapter () is the Bluetooth adapter obtaining acquiescence, and method getBondedDevices () obtains the local equipment matched.Method getName () is the title obtaining paired device, and the effect of method getAddress () is the physical address obtaining paired device.The bluetooth device name and the physical address that obtain by eject after press " connection " button in homepage dialog box in show.Need the class used to be that Intent, Intent effect herein is mainly applied when pressing " connections " button and jumped to device_list.xml layout corresponding to the list of devices page from the sensor.xml layout that homepage is corresponding when jumping to from homepage and selecting dialogue frame.Embodiment is: create an equipment class, be named as DeviceActivity.LinearLayout layout type is adopted in the topology file device_list.xml that DeviceActivity.java is corresponding, the distribution vertically downward of acquiescence is adopted to carry out layout, be followed successively by TextView and ListView from top to bottom, wherein TextView is used for display " please select the equipment that you will connect ", and ListView is for showing the bluetooth equipment of acquisition.In DeviceActivity.java, create BluetoothAdapter object, be named as mBtAdapter, create ArrayAdapter<String> object, be named as mPairedDevicesArrayAdapter.Then Application way setContentView (R.layout.devicelist) comes display layout interface, and the bluetooth equipment then by obtaining fills layout above.The concrete mode obtaining bluetooth equipment is broadly divided into a few step below: create listView class listview, create page display adapter mPairedDevicesArrayAdapter, local bluetooth adapter is created by getDefaultAdapter () method, definition Set<BluetoothDevice> class, be named as pairedDevices, obtain one group of bluetooth equipment matched by getBondedDevices () method.Then Application way size () judges acquired bluetooth equipment quantity, if be not 0, obtains the title of bluetooth equipment and then physical address utilizes add () method bluetooth device name and physical address to be added in page display adapter mPairedDevicesArrayAdapter by getName () and getAddress ().Then by setAdapter () method binding mPairedDevicesArrayAdapter, show in the page finally by method setContentView (listview).If the number of devices obtained is 0, do not carry out any process.The bluetooth equipment that finally also will obtain these adds response events, concrete processing mode is: utilize the establishment of setOnItemClickListener () method to the response clicking bluetooth equipment event, the information that Application way getText () .toString () obtains the equipment clicked is assigned to String variable i nfo, utilizes the substring of info (info.length ()-17) method to obtain the address of the equipment clicked.Then create intent object, object address information is delivered in the operation that will carry out.Call setResult (Activity.RESULT_OK, intent) carry out the transmission of information, then call finish () and return homepage and the onActivityResult () method called in SensorActivity.java processes accordingly.Attention must add android:name=" com.mfg.garden.DeviceActivity " in AndroidManifest.xml, and the effect of this section of code is the page open that application program allows that DeviceActivity.class is corresponding.In addition be the page being similar to dialog box due to what will show, so place that will be corresponding with android:name=" com.mfg.garden.DeviceActivity " in AndroidManifest.xml adds android:theme="@android:style/Theme.Dialog ".
(3) bluetooth is connected
If want to allow two bluetooth equipments proper communication just can must set up connection between two equipment, therefore a service end and client must be defined, be exactly client as the smart mobile phone of receiving end in the utility model, and the bluetooth module of transmitting terminal is exactly service end.The class used is needed to have BluetoothServerSocket and BluetoothSocket.Two noun RFCOMM and UUID first must be mentioned before being described in detail.Wherein RFCOMM is a linear simulation protocol of serial based on ETSI ETSI07.10 code, its objective is and to ensure a complete communication path between the application for how on two distinct devices, and keep a communication section between which.And UUID is a kind of general exclusive identification code (UniversallyUniqueIdentifier), refer to the numeral generated on a machine, it ensures all machines at same space-time is all unique.Judge that the standard whether two bluetooth equipments have connected is exactly see whether two equipment have a BluetoothSocket connected respectively under same RFCOMM passage.But the mode that server device and client device obtain BluetoothSocket is distinguished again to some extent.Server device obtains by accepting a connection on the horizon, and client device is then obtain by opening a RFCOMM passage to server apparatus.Illustrate the obtain manner of two kinds of modes below:
Service end realizes
BluetoothServerSocket (UUID is used for the pairing between client and server) is obtained by the listenUsingRfcommWithServiceRecord () method calling BluetoothAdapter.And then the accept () method calling BluetoothServerSocket class is to monitor connection request, if the request that receives just returns a BluetoothSocket example.Because this method be in the pre-connection the moment running, be therefore necessary to place it in a thread and perform, the title of this thread is exactly AcceptThread in the present embodiment.Can not want although mobile phone terminal is that is this AcceptThread thread existed as client, accept thread AcceptThread in order to the integrality applied still with the addition of.When not thinking the connection request accepting other again, then the close () method calling BluetoothServerSocket class is needed to remove releasing resource.It should be noted that after calling close () method, the BluetoothSocket example before obtained is not closed.Because RFCOMM can only have a connection at any one time in a passage, so under normal circumstances after reception one connects, just close BluetoothServerSocket.
The realization of client
The BluetoothService of server end is obtained by search.Call the listenUsingRfcommWithServiceRecord () method of BluetoothAdapter to obtain BluetoothSocket (UUID now should be equal with the UUID of server end).Then the connect () method of BluetoothSocket is called.Because this method is also a time-consuming operation, therefore defines one and connect thread, be named as ConnectThread.The connection status of two bluetooth equipments can be passed out and shown by Toast class in the page in thread ConnectThread.If the UUID of the UUID of client and service end matches and the serviced termination of connection request is subject to, then connect () method returns.
(4) data transmission
Receive only data that sensor collects in present embodiment and do not send corresponding control command, therefore whole application only relates to the reception of data and does not relate to the transmission of data.For managing the thread of connection after this defines two bluetooth equipments connection, be named as ConnectedThread, this thread is in charge of the data communication problem after connection.First a BluetoothSocket class mmSocket and InputStream class mmInStream is defined, in ConnectedThread () method, utilize getInputStream () method to obtain inlet flow, then in run (), define an impact damper buffer and shaping variable bytes of a byte type array, the buffer value read is assigned to bytes by Application way read (bytes []), finally bytes is passed to sensor interface by handler, what pass the past identifies SensorActivity.MESSAGE_READ simultaneously in addition, notice that the circulation of this process is carried out, similar with the circulation in single-chip microcomputer.Next, in the Handler class mHandler in SensorActivity.java, the reception of sensor values can be carried out when the value of msg.what is SensorActivity.MESSAGE_READ, finally show in the EditText of correspondence.
Above-mentioned Bluetooth communication is the state of the art, and the application does not make improvements, and is described herein just in order to those skilled in the art can be allowed better to understand the application.
Intelligence receiving end is also by shaking the sensing data that real-time broadcasting collects.Because the TTS that existing Android system carries only supports that English is read aloud, finally determine through data of searching and use news to fly voice packet to carry out Chinese report, finally also reach sound clarity, good result that word speed is moderate.Do the redirect of triggering page by shaking a shake, this time redirect is from page jump corresponding to sensor.xml layout to the page corresponding to voice.xml layout.The page after redirect is the page having " loudspeaker " pattern, represents and carries out voice broadcast.In the process of redirect, need the numerical value of sensor to be delivered to the page corresponding to voice.xml layout from the page that sensor.xml layout is corresponding, that time after redirect starts speech engine, reports.
