posting to pushingbox with GPRS

HI All,

Hope you can help.

The following works fine to post to PushingBox:
gprsSerial.println("AT+HTTPPARA="URL","http://api.pushingbox.com/pushingbox?devid=v644DEB15F1Annnn&EMP1_Temperature=*23*\"");

How can I replace "23" with a variable?
For instance, the following does not work:
int temp=23;
gprsSerial.println("AT+HTTPPARA="URL","http://api.pushingbox.com/pushingbox?devid=v644DEB15F1Annnn&EMP1_Temperature=[u]temp[/u]\"");

Please help.

You should be able to accomplish what you want by using sprintf() to format the string. Try out this example:

void setup() {

  Serial.begin(9600);  

  char buffer[120];    // buffer for formatted string
  int temp=23;         // variable for temperature

  // string with formatting specifications
  char * msg = "AT+HTTPPARA=\"URL\",\"http://api.pushingbox.com/pushingbox?devid=v644DEB15F1Annnn&EMP1_Temperature=%d\"";

  // format buffer 
  sprintf(buffer,msg,temp);

  Serial.println(buffer);


}

void loop() {


}
