WIFly + Pachube?

Hello there,

I have some problems with the Wifly from Sparkfun.
I want the Arduino+Wifly to autoconnect to a router and then updating my Pachube-Feeds.

The autoconnect works fine and when I'm using a terminal I'm able to update the feed manually with following lines:

open pachube.com 80

POST /api/9837.csv?_method=put HTTP/1.1
Host: www.pachube.com
X-PachubeApiKey: MYAPI
Content-type: text/csv
Content-Length: 5
Connection: close

45,70

I've tried following code for the autoupdate, but it doens't work - any ideas why?

void pachube(){
SPI_Uart_print("open pachube.com 80\r\n");
delay(2500);
SPI_Uart_println("POST /api/9837.csv?_method=put HTTP/1.1\r\n");
SPI_Uart_print("Host: www.pachube.com\r\n");
SPI_Uart_print("X-PachubeApiKey: MYAPI \r\n");
SPI_Uart_print("Content-type: text/csv\r\n");
SPI_Uart_print("Content-Length: 6\r\n");
SPI_Uart_print("Connection: close\r\n");  // note extra blank line
SPI_Uart_print("\r\n");
SPI_Uart_print("200,50\r\n");

}

Thanks for your suggestions!

SPI_Uart_print[glow]ln[/glow]("POST /api/9837.csv?_method=put HTTP/1.1[glow]\r\n[/glow]");
SPI_Uart_print("Host: www.pachube.com\r\n");

You are sending a blank line, which typically says "We're all done". You aren't, are you?

Well, I removed the ,,ln''. But when I remove the blank line(\r\n) it flows together like:

(...)HTTP/1.1HOST: www.pachube.com.....

Don't know what else could I do.

You need to use EITHER println or the \r\n, but not both.

Ah oke, I see. Well, but it doesn't help to get the things work.
I think there are some other problems.
Are there any opportunities to check if the connection to the Pachube server is opened?
My code snippet looks like this for now:

void loop()
{
  //EXIT command mode
  //SPI_Uart_println("exit");
    
  Serial.println("OPEN PACHUBE");
  delay(1000);
  SPI_Uart_println("open pachube.com 80");
  delay(5000);
  SPI_Uart_print("POST /api/9837.csv?_method=put HTTP/1.1\r\n");
  SPI_Uart_print("Host: www.pachube.com\r\n");
  SPI_Uart_print("X-PachubeApiKey: e147d9049f3c23b1fc1109acc5e1d67ea817238ceb6c7275b41af7ce8b2d7738\r\n");
  SPI_Uart_print("Content-Length: 2\r\n");
  SPI_Uart_print("Connection: close\r\n");  
  SPI_Uart_print("\r\n");
  SPI_Uart_print("56\r\n");
  Serial.println("ENDE!");
  
  delay(10000);
  
    

  


  // Terminal routine
  if(SPI_Uart_ReadByte(LSR) & 0x01) // Incoming data
  { 
    polling = 1;
    i = 0;
    while(polling)
    {
      if((SPI_Uart_ReadByte(LSR) & 0x01))
      {
        incoming_data = SPI_Uart_ReadByte(RHR);
        Serial.print(incoming_data,BYTE);
        //Serial.print(incoming_data, HEX);
        //Serial.print(" ");
      }  
      else
      {
        polling = 0;
      }
    }

  }
  else if(Serial.available()) // Outgoing data
  {
    incoming_data = Serial.read();
    select();
    spi_transfer(0x00); // Transmit command
    spi_transfer(incoming_data);
    deselect();
  }

}

Hi,

You might want to try the WiFly library for Arduino I created: WiFly Shield code library alpha.

--Philip;

P.S. Also, you probably shouldn't have your API key visible. :slight_smile:
