「Xively GPRS主站庫」用sim900 icomsat盾爲arduino GET示例

Question

我試圖從Xively_GPRS主站庫（https://github.com/Seeed-Studio/Xively_GPRS）使用此示例來獲取xively網站的數據，對於Arduino的串口監視器：

「從Xively例如

IP = 191.171.127.94讀」 我使用的是icomsat 1.1 SIM900從Itead工作室基於Arduino的盾牌。

有人可以幫助我嗎？謝謝！

#include <GPRSClient.h> 
#include <Xively.h> 
#include <SoftwareSerial.h> 

#define PIN_TX 2 
#define PIN_RX 3 

// Your Xively key to let you upload data 
char xivelyKey[] = "yGr24HFXpc2IVMACSdmyypR9d6ubk8XX2f3RRFJ2phhR96AR"; 

// Define the string for our datastream ID 
char sensorId[] = "sensor"; 

XivelyDatastream datastreams[] = { 
    XivelyDatastream(sensorId, strlen(sensorId), DATASTREAM_FLOAT), 
}; 
// Finally, wrap the datastreams into a feed 
XivelyFeed feed(675207838, datastreams, 1 /* number of datastreams */); 

char apn[] = "tim.br"; 
char user[] = "tim"; 
char pass[] = "tim"; 
GPRSClient gprs(PIN_TX,PIN_RX,4800,apn,user,pass); 
XivelyClient xivelyclient(gprs); 

void setup() { 
    // put your setup code here, to run once: 
    Serial.begin(4800); 

    Serial.println("Reading from Xively example"); 
    Serial.println(); 

    gprs.init(); 
    while(false == gprs.join()) { 
    Serial.println("connect error"); 
    delay(2000); 
    } 

    // successful DHCP 
    Serial.print("IP ="); 
    Serial.println(gprs.getIPAddress()); 
} 

void loop() { 
    int ret = xivelyclient.get(feed, xivelyKey); 

    if (ret > 0){ 
    Serial.println("Datastream is..."); 
    Serial.println(feed[0]); 
    Serial.print("Temperature is: "); 
    Serial.println(feed[0].getFloat()); 
    } 


    Serial.println(); 
    delay(15000UL); 
}

很難說出問題在這裏。你能發佈你的串口監視器輸出嗎？另外，您是否在Xively Workbench請求日誌中看到任何請求？那將是首先檢查的地方。
