在以下源代码中，我使用带有跳线tsData的 GBoard Itead Sim900 将ST->D2, SR->D3的内容发送到服务器和 GSMShield库（GSM_GPRSLibrary_AT，GSM_GPRSLibrary_Call，GSM_GPRSLibrary_Client，GSM_GPRSLibrary_GPS，GSM_GPRSLibrary_Server，GSM_GPRSLibrary_SMS）
但是， GBoard似乎无法连接到 ThingSpeak 服务器。
你能帮我修理bevahiour吗？
我有这段代码：
const byte DATA = 8;
int cont1=0;
int cont2=0;
int cont3=0;
int connectTCP;
unsigned long time;
#include "SIM900.h"
#include <SoftwareSerial.h>
#include "inetGSM.h"
//#include <GSM.h>
//#include <SPI.h>
//#include <Ethernet.h>
//#include "sms.h"
//#include "call.h"
InetGSM inet;
#define PINNUMBER ""
// APN data
#define GPRS_APN "-" // replace your GPRS APN
#define GPRS_LOGIN "-" // replace with your GPRS login
#define GPRS_PASSWORD "-" // replace with your GPRS password
char serverAddress[] = "server.com";
String writeAPIKey = "---";
long lastConnectionTime = 0;
boolean lastConnected = false;
boolean started=false;
int failedCounter = 0;
void setup()
{
// Start Serial for debugging on the Serial Monitor
Serial.begin(9600);
Serial.println("GSM Shield testing.");
//Start configuration of shield with baudrate.
//For http uses is raccomanded to use 4800 or slower.
if (gsm.begin(2400)){
Serial.println("\nstatus=READY");
started=true;
}
else Serial.println("\nstatus=IDLE");
// connection state
boolean notConnected = true;
// After starting the modem with GSM.begin()
// attach the shield to the GPRS network with the APN, login and password
while(notConnected)
{
if(inet.attachGPRS(GPRS_APN, GPRS_LOGIN, GPRS_PASSWORD))
notConnected = false;
else
{
Serial.println("Not connected");
delay(1000);
}
}
}
void loop()
{
time = millis()/999;
}
// if there's incoming data from the net connection.
// send it out the serial port. This is for debugging
// purposes only:
if (gsm.available())
{
char c = gsm.read();
Serial.print(c);
}
// Disconnect from server
if (!gsm.available() && lastConnected)
{
Serial.println("...disconnected");
Serial.println();
int disconnectTCP();
}
// Update server
if(!gsm.available() && (millis() - lastConnectionTime > 120000))
{
funtcion a();//[Example]
}
}
// Check if gsmboard needs to be restarted
//if (failedCounter > 3 ) {startEthernet();}
//lastConnected = client.connected();
void updateServer(String tsData)
{
if (inet.connectTCP(serverAddress, 80))
{
gsm.SimpleWrite("POST /update HTTP/1.1\n");
gsm.SimpleWrite("Host: server.com\n");
gsm.SimpleWrite("Connection: close\n");
gsm.SimpleWrite("SERVER: ");
gsm.SimpleWrite("writeAPIKey");
gsm.SimpleWrite("\n");
gsm.SimpleWrite("Content-Type: application/x-www-form-urlencoded\n");
gsm.SimpleWrite("Content-Length: ");
gsm.SimpleWrite(tsData.length());
gsm.SimpleWrite("\n\n");
gsm.SimpleWrite(tsData.c_str());//----IN THIS LINE I THINK IS THE PROBLEM----
lastConnectionTime = millis();
if (inet.connectedClient())
{
Serial.println("Connecting to SERVER...");
Serial.println();
failedCounter = 0;
}
else
{
failedCounter++;
Serial.println("Connection to SERVERfailed ("+String(failedCounter, DEC)+")");
Serial.println();
}
}
else
{
failedCounter++;
Serial.println("Connection to SERVERFailed ("+String(failedCounter, DEC)+")");
Serial.println();
lastConnectionTime = millis();
}
}
， 这是控制台中的输出：
