Hey! I had read a few posts asking about this subject, but I couldn't find the solution. I was trying to use CuHead v1 WiFi Shield to send a GET request to my local server, but looks like the library and the examples isn't working properly. Here follows the code:
ArduinoCode.pde
/*
* A simple sketch that uses WiServer to get the hourly weather data from LAX and prints
* it via the Serial API
*/
#include <WiShield.h>
#include <WiServer.h>
#define WIRELESS_MODE_INFRA 1
#define WIRELESS_MODE_ADHOC 2
// Wireless configuration parameters ----------------------------------------
unsigned char local_ip[] = {192,168,1,2}; // IP address of WiShield
unsigned char gateway_ip[] = {192,168,1,1}; // router or gateway IP address
unsigned char subnet_mask[] = {255,255,255,0}; // subnet mask for the local network
const char ssid[] PROGMEM = {"MY SSID NETWORK"}; // max 32 bytes
unsigned char security_type = 3; // 0 - open; 1 - WEP; 2 - WPA; 3 - WPA2
// WPA/WPA2 passphrase
const char security_passphrase[] PROGMEM = {"MYPASSWORD"}; // max 64 characters
// WEP 128-bit keys
// sample HEX keys
const char PROGMEM 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 ----------------------------------------
// 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.
while (len-- > 0) {
Serial.print(*(data++));
}
}
// IP Address for www.weather.gov
uint8 ip[] = {192,168,1,2};
// A request that gets the latest METAR weather data for LAX
GETrequest getWeather(ip, 80, "localhost", "/index.php?id=1");
void setup() {
// Initialize WiServer (we'll pass NULL for the page serving function since we don't need to serve web pages)
WiServer.init(NULL);
// Enable Serial output and ask WiServer to generate log messages (optional)
Serial.begin(57600);
WiServer.enableVerboseMode(true);
// Have the processData function called when data is returned by the server
getWeather.setReturnFunc(printData);
}
// Time (in millis) when the data should be retrieved
long updateTime = 0;
void loop(){
// Check if it's time to get an update
if (millis() >= updateTime) {
getWeather.submit();
// Get another update one hour from now
updateTime += 1000 * 60 * 60;
}
// Run WiServer
WiServer.server_task();
delay(10);
}
This code give me this errors:
ArduinoCode.pde:57:1: error: 'GETrequest' does not name a type
ArduinoCode.pde: In function 'void setup()':
ArduinoCode.pde:69:3: error: 'getWeather' was not declared in this scope
ArduinoCode.pde: In function 'void loop()':
ArduinoCode.pde:80:5: error: 'getWeather' was not declared in this scope
I had to paste the code into PasteBin because of the 900 characters limit of the forum.
