Salve a tutti,
ho un problema riguardo l'invio di tweet a twitter tramite lo shield gsm di arduino, in pratica utlizzo il metodo httPost della libreria inetGsm, ma quando scrivo lo sketch per provare se il tutto funziona(carico lo sketch di esempio del gsmClient della libreria),quando inserisco il metodo sopraindicato non succede nulla,esce solo la scritta gsm shiel testing, se tolgo il comando httpPost si collega a internet in cosa sbaglio?
vi posto il codice:
#include "SIM900.h"
#include <SoftwareSerial.h>
#include "inetGSM.h"
//#include "sms.h"
//#include "call.h"
//To change pins for Software Serial, use the two lines in GSM.cpp.
//GSM Shield for Arduino
//www.open-electronics.org
//this code is based on the example of Arduino Labs.
//Simple sketch to start a connection as client.
InetGSM inet;
//CallGSM call;
//SMSGSM sms;
char msg[50];
int numdata;
char inSerial[50];
int i=0;
boolean started=false;
void setup()
{
//Serial connection.
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");
if(started){
//GPRS attach, put in order APN, username and password.
//If no needed auth let them blank.
if (inet.attachGPRS("internet.wind", "", ""))
Serial.println("status=ATTACHED");
else Serial.println("status=ERROR");
delay(1000);
//Read IP address.
gsm.SimpleWriteln("AT+CIFSR");
delay(5000);
//Read until serial buffer is empty.
gsm.WhileSimpleRead();
//TCP Client GET, send a GET request to the server and
//save the reply.
numdata=inet.httpPOST("arduino-tweet.appspot.com",80,"/update", "token=mioToken&status=DaARDUINO",msg, 50);
//Print the results.
Serial.println("\nNumber of data received:");
// Serial.println(numdata);
Serial.println("\nData received:");
Serial.println(msg);
}
};
void loop()
{
//Read for new byte on serial hardware,
//and write them on NewSoftSerial.
// serialhwread();
//Read for new byte on NewSoftSerial.
//serialswread();
};
/void serialhwread(){
i=0;
if (Serial.available() > 0){
while (Serial.available() > 0) {
inSerial=(Serial.read());*
- delay(10);*
- i++; *
- }*
_ inSerial*='\0';_
_ if(!strcmp(inSerial,"/END")){_
Serial.println("");
_ inSerial[0]=0x1a;*
* inSerial[1]='\0';*
* gsm.SimpleWriteln(inSerial);*
* }*
* //Send a saved AT command using serial port.*
* if(!strcmp(inSerial,"TEST")){*
* Serial.println("SIGNAL QUALITY");*
* gsm.SimpleWriteln("AT+CSQ");*
* }*
* //Read last message saved.*
* if(!strcmp(inSerial,"MSG")){*
* Serial.println(msg);*
* }*
* else{*
* Serial.println(inSerial);*
* gsm.SimpleWriteln(inSerial);*
* } *
* inSerial[0]='\0';*
* }*
}
void serialswread(){
* gsm.SimpleRead();*
