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

BlackBerry NDK C/C++ API封装了蓝牙SPP API，用起来稍微复杂一点（和Android API类似），连接蓝牙设备的时候，bt_spp_open()方法需要对方的服务UUID，mac地址。
下载BlackBerry 蓝牙例子代码bluetoothsppchat，导入到NDK中，build，运行即可。
注意其中的UUID的定义：
#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]
参考：
蓝牙串口服务 UUID '{00001101-0000-1000-8000-00805F9B34FB}'
