AsyncLabs WiShield 2.0 two way communication

My garage door project is starting to expand a bit.

The controller for it will now also monitor my mail box, and send a mail directly to my mobile phone running Android. But to do that best, and in real time, I had to make the WiShield 2.0 and Arduino be able to both recieve the commands from the webpage, telling it to turn the stuff on and off, plus also send a notification to my NAS to tell it that it should send me an email.

After looking a bit in both the server and client example, I noticed that it wasn’t that big a difference between them.

I did a bit copy and pasting and edited the code a bit, and here is my result.

#include "WiServer.h";
#define WIRELESS_MODE_INFRA	1
#define WIRELESS_MODE_ADHOC	2

// Wireless configuration parameters ----------------------------------------
unsigned char local_ip[] = {10,0,0,15};	// IP address of WiShield
unsigned char gateway_ip[] = {10,0,0,1};	// router or gateway IP address
unsigned char subnet_mask[] = {255,0,0,0};	// subnet mask for the local network
const prog_char ssid[] PROGMEM = {"dd-wrt"};		// max 32 bytes

unsigned char security_type = 3;	// 0 - open; 1 - WEP; 2 - WPA; 3 - WPA2

// WPA/WPA2 passphrase
const prog_char security_passphrase[] PROGMEM = {"xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"};	// max 64 characters

// WEP 128-bit keys
// sample HEX keys
prog_uchar wep_keys[] PROGMEM = { 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07, 0x08, 0x09, 0x0a, 0x0b, 0x0c, 0x0d,	// Key 0
				  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,	// Key 1
				  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00,	// Key 2
				  0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00	// Key 3
				};

// setup the wireless mode
// infrastructure - connect to AP
// adhoc - connect to another WiFi device
unsigned char wireless_mode = WIRELESS_MODE_INFRA;

unsigned char ssid_len;
unsigned char security_passphrase_len;
// End of wireless configuration parameters ----------------------------------------

unsigned long timeDebounce = 30000;
unsigned long inputDebounce = 0;

// Function that prints data from the server
void printData(char* data, int len)
{
  // Print the data returned by the server
  // Note that the data is not null-terminated, may be broken up into smaller packets, and
  // includes the HTTP header.

  Serial.print(data);

  //while (len-- > 0)
  //{
    //Serial.print(*(data++));
  //}
  //delay(100);
}

//IP of my NAS
uint8 ip[] = {10,0,0,117};

//Define the request
GETrequest pullServer(ip, 80, "10.0.0.117", "");

// This is our page serving function that generates web pages
boolean sendMyPage(char* URL)
{
  if (strcmp(URL, "/toggle5") == 0)
  {
  }

  WiServer.print("OK");
  return true;
}

void setup()
{
  Serial.begin(9600);

  pullServer.setReturnFunc(printData);
  WiServer.init(sendMyPage);
}

void loop()
{
  if (millis() - inputDebounce >= timeDebounce && analogRead(5) > 0) //One minute debounce
  {
    inputDebounce = millis();

    //char newURL[32];
    //sprintf(newURL, url, var);

    pullServer.setURL("/arduino/control/call.php?status=mail");
    pullServer.submit();
  }

  delay(500);

  // Run WiServer
  WiServer.server_task();
}

It will then call http://10.0.0.117/arduino/control/call.php?status=gotmail when it is more than 60 seconds since last time (to allow the postman to close the lid again without spamming me) and when the digital pin 2 is HIGH (5V input)

The call.php is very simple too

<?php
if (isset($_GET["status"]))
{
	if($_GET["status"] == "gotmail")
	{
		mail("[email protected]", "You got mail!", "Wohoo, go check it!", "from:[email protected]");
	}
}
?>
