I have defined the temp0, temp1 ... values as "int". How can put them to sprintf(...)? Manual send was : &field1=200&field2=200 ....
instead of 200 i have to put the temp0, temp1 ....
I'm going to be happy
current code is here: SKETCH
answer is:
Starting ethernet...

85 degrees is maybe some kind of delay I guess...
we are almost at the start of writing to SD
edit: I have modified the char array to 140. As API documentation said that is the maximum. Can I modify later the temp as float?
Watch out for type float. If you try to use that type in sprintf, the result will be "?" where you expected the value to be. You need to convert that float to a string first.
Is the value returned from the temperature sensor a float type? Or integer?
edit: Some devices return the temperature in fractions of a degree, like half or quarter of a degree. 85 may be in quarter degrees. That would be 21.25 degrees Celsius.
I have tried that, I will stay at integer ( i gues return value can be a float)...I hope it will show negative values.
Facing to SD writing...I have put the SD code what you wrote to the setup().
Can you help how should I go ahaed?
it was my original SD code:
#include <Wire.h>
#include <OneWire.h>
#include <Rtc_Pcf8563.h>
#include <SD.h>
//init the real time clock
Rtc_Pcf8563 rtc;
// Global variables
const int period = 30000;
const int chipSelect = 8;
//**************************SETUP*****************************
void setup()
{
String message="";
Serial.begin(9600);
Wire.begin();
pinMode(8, OUTPUT);
if (!SD.begin(chipSelect))
{
Serial.println("Card failed");
return;
}
Serial.println("Card init");
File logFile = SD.open("errorlog.txt", FILE_WRITE);
if (logFile)
{
message = String(rtc.formatDate(RTCC_DATE_ASIA)) + " " + String(rtc.formatTime());
logFile.println("Progstart: " + message);
logFile.close();
Serial.println("Progrstart: " + message);
}
// if the file isn't open, pop up an error:
else
{
Serial.println("cannot open errorlog.txt");
}
}
//********************LOOP**********************************
void loop()
{
delay(period);
// make a string for assembling the data to log:
String dataString = "";
String sDate = "";
String sTime ="";
//-------------------------------------------------------------
sTime=rtc.formatTime(); //read formatted time from i2C RTC
sDate=rtc.formatDate(RTCC_DATE_ASIA); //read formatted date from 12C RTC
Serial.print(sTime);
Serial.print(" ");
Serial.print(sDate);
Serial.println();
dataString += String(sDate + ";" + sTime + ";");
delay(100);
File dataFile = SD.open("datalog.txt", FILE_WRITE);
if (dataFile)
{
dataFile.println(dataString);
dataFile.close();
// print to the serial port too:
Serial.println(dataString);
}
// if the file isn't open, pop up an error:
else
{
Serial.println("cannot open datalog.txt");
}

// END LOOP
or should I use your ftp code?? Seems I will need your further help

UPDATE: strange...without the logfile modification, it is not connecting...that was working fine before...maybe thingspeak issue...
