 Bigger Bigger  Smaller Smaller  Reset Reset

Hello,
I'm attempting to retrieve some phps from my new Adafruit CC3000 Library using the Webclient example and it works fine for all "internet" sites but I can't seem to get it to work for my local server.

Here is my Arduino Code:
Code:
#include <Adafruit_CC3000.h>
#include <ccspi.h>
#include <SPI.h>
#include <string.h>
#include "utility/debug.h"

// These are the interrupt and control pins
#define ADAFRUIT_CC3000_IRQ   3  // MUST be an interrupt pin!
// These can be any two pins
#define ADAFRUIT_CC3000_VBAT  5
#define ADAFRUIT_CC3000_CS    10
Adafruit_CC3000 cc3000 = Adafruit_CC3000(ADAFRUIT_CC3000_CS, ADAFRUIT_CC3000_IRQ, ADAFRUIT_CC3000_VBAT,SPI_CLOCK_DIVIDER);

#define WLAN_SSID       "MikroTik"
#define WLAN_PASS       "7409721385"
// Security can be WLAN_SEC_UNSEC, WLAN_SEC_WEP, WLAN_SEC_WPA or WLAN_SEC_WPA2
#define WLAN_SECURITY   WLAN_SEC_WPA2

//#define WEBSITE "http://192.168.88.240"
//#define WEBPAGE "/Home_Automation/checkStatus.php?DeviceCount=3&Type=Toggles&Device0=HVAC_Fan&Device1=HVAC_Ac&Device2=HVAC_Heat"

#define WEBSITE      "192.168.88.240"
#define WEBPAGE      "/home_automation/test.php"

#define IDLE_TIMEOUT_MS  3000      // Amount of time to wait (in milliseconds) with no data
                                   // received before closing the connection.  If you know the server
                                   // you're accessing is quick to respond, you can reduce this value.
uint32_t ip = cc3000.IP2U32(192, 168, 88, 240);

The http:// is missing in one of the below.

Code:
//#define WEBSITE "http://192.168.88.240"

Consider the daffodil. And while you're doing that, I'll be over here, looking through your stuff.   smiley-cool
