目标：BlackBerry手机通过蓝牙串口读取Arduino 蓝牙传过来的温度 湿度信息

硬件：Arduino主板 + DHT11温湿度传感器 + 蓝牙模块，开发工具C语言

手机：BlackBerry 9360手机，OS 7.1，开发工具Java

手机：BlackBerry 10 Alpha手机，OS  10.0.xxx，开发工具BlackBerry 10 NDK

通讯：手机和Arduino通过蓝牙连接

BlackBerry 9360手机上面的显示：湿度41，温度11（哈冷啊。。。。。。。。。。。。。。。。）

Arduino代码参考这里 http://playground.arduino.cc/Main/DHTLib

代码如下：

// //   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封装了串口通讯，所以用起来就很方便了。

开发工具eJDE中导入sample程序BluetoothSerialPortDemo ，修改代码接收蓝牙数据并显示在文本框中。

                        // 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() 出来的数据是0x0d, 0x0a。在Java中，我只检测回车字符  (char)0x0a作为一条数据的分隔符即可

//! [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) );    }}//!
