目標：BlackBerry手機通過藍牙串口讀取Arduino 藍牙傳過來的溫度 濕度信息

硬件：Arduino主板 + DHT11溫濕度傳感器 + 藍牙模塊，開發(fā)工具C語言

手機：BlackBerry 9360手機，OS 7.1，開發(fā)工具Java

手機：BlackBerry 10 Alpha手機，OS ?10.0.xxx，開發(fā)工具BlackBerry 10 NDK

通訊：手機和Arduino通過藍牙連接

BlackBerry 9360手機上面的顯示：濕度41，溫度11（哈冷啊。。。。。。。。。。。。。。。。）

Arduino代碼參考這里?http://playground.arduino.cc/Main/DHTLib

代碼如下：

// //?? FILE:? dht_test.pde// PURPOSE: DHT library test sketch for Arduino//#include <dht.h>dht DHT;#define DHT11_PIN 8#define DHT22_PIN 5void setup(){? Serial.begin(9600);? Serial.println("DHT TEST PROGRAM ");? Serial.print("LIBRARY VERSION: ");? Serial.println(DHT_LIB_VERSION);? Serial.println();? Serial.println("Type,\tstatus,\tHumidity (%),\tTemperature (C)");}void loop(){? // READ DATA? int chk;?? // READ DATA? Serial.print("DHT11, \t");? chk = DHT.read11(DHT11_PIN);? switch (chk)? {??? case DHTLIB_OK:? ??Serial.print("OK,\t"); ??break;??? case DHTLIB_ERROR_CHECKSUM: ??Serial.print("Checksum error,\t"); ??break;??? case DHTLIB_ERROR_TIMEOUT: ??Serial.print("Time out error,\t"); ??break;??? default: ??Serial.print("Unknown error,\t"); ??break;? }?// DISPLAT DATA? Serial.print(DHT.humidity,1);? Serial.print(",\t");? Serial.println(DHT.temperature,1);? delay(1000);}//// END OF FILE//

BlackBerry ?OS 7.1

BlackBerry Java API封裝了串口通訊，所以用起來就很方便了。

開發(fā)工具eJDE中導(dǎo)入sample程序BluetoothSerialPortDemo?，修改代碼接收藍牙數(shù)據(jù)并顯示在文本框中。

? ? ? ? ? ? ? ??

??????????????????????? // Read in the contents and get the event lock for this??????????????????????? // application so we can update the info field.??????????????????? ?Util.log("Read bluetooth data...");??????????????????? ?int i = 0;??????????????????? ?while(true){??????????????????? ??i++;??????????????????????????? String cmd = "";??????????????????????????? byte b;??????????????????????????? while ((( b = _din.readByte()) > 0) &&( (char)b != ((char)0x0a)) ){??????????????????????????? ?cmd = cmd + (char)b;??????????????????????????? } ??????????????????????????? ??????????????????????????? Util.log("Received " + cmd);??????????????????????????? _infoField.setText(i + ": " + cmd);??????????????????????? }?????????????????????
注：

Arduino中，Serial.println() 出來的數(shù)據(jù)是0x0d, 0x0a。在Java中，我只檢測回車字符 ?(char)0x0a作為一條數(shù)據(jù)的分隔符即可

BlackBerry ?OS 10

BlackBerry NDK C/C++ API封裝了藍牙SPP API，用起來稍微復(fù)雜一點（和Android API類似），連接藍牙設(shè)備的時候，bt_spp_open()方法需要對方的服務(wù)UUID，mac地址。

下載BlackBerry 藍牙例子代碼bluetoothsppchat，導(dǎo)入到NDK中，build，運行即可。

注意其中的UUID的定義：

#define SPP_SERVICE_UUID "00001101-0000-1000-8000-00805F9B34FB"

//! [7]void ChatManager::connectToSPPService(){??? m_chatHistory.clear();??? const int fd = bt_spp_open(m_remoteAddress.toAscii().data(), (char *) SPP_SERVICE_UUID, false);??? if (fd >= 0) {??????? updateChatWindow("SPP Client\n\n");??????? setSPPClient(fd);??? } else {??????? showDialog("spp_open fail", "errno = " + QString::number(errno) );??? }}//! [7]BB 10運行效果如圖

參考：

藍牙串口服務(wù) ?UUID ? '{00001101-0000-1000-8000-00805F9B34FB}'?
