Hallo Gemeinde,
ich versuche das Beispiel Wifi WebClient zubenutzen doch es funktioniert nicht und ich sehe keinen Lösungsansatz
Verwenden tue ich ein Arduino Mega 2560 mit originalem Arduino WiFi Shield.
Der Verbindungsaufbau zum Netzwerk scheint zufunktionieren aber der connect zum Server schlägt wohl fehl.
Hab ihr evt eine Lösung für mich parat?
Hier noch die SerialMoitor ausgabe:
Attempting to connect to SSID: FRITZ!Box 6360 Cable
Connected to wifi
SSID: FRITZ!Box 6360 Cable
IP Address: 192.168.0.23
signal strength (RSSI):-62 dBm
Starting connection to server...
Connection fail
disconnecting from server.
#include <SPI.h>
#include <WiFi.h>
char ssid[] = "FRITZ!Box 6360 Cable"; // your network SSID (name)
char pass[] = "xxxxxXXXxxxx"; // your network password (use for WPA, or use as key for WEP)
int keyIndex = 0; // your network key Index number (needed only for WEP)
int status = WL_IDLE_STATUS;
// if you don't want to use DNS (and reduce your sketch size)
// use the numeric IP instead of the name for the server:
IPAddress server(173,194,73,105); // numeric IP for Google (no DNS)
//char server[] = "www.google.com"; // name address for Google (using DNS)
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
WiFiClient client;
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
while (!Serial) {
; // wait for serial port to connect. Needed for Leonardo only
}
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
// don't continue:
while(true);
}
// attempt to connect to Wifi network:
while ( status != WL_CONNECTED) {
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
status = WiFi.begin(ssid, pass);
// wait 10 seconds for connection:
delay(10000);
}
Serial.println("Connected to wifi");
printWifiStatus();
Serial.println("\nStarting connection to server...");
// if you get a connection, report back via serial:
if (client.connect(server, 80)) {
Serial.println("connected to server");
// Make a HTTP request:
client.println("GET /search?q=arduino HTTP/1.1");
client.println("Host:www.google.com");
client.println("Connection: close");
client.println();
}
else {
Serial.print("Connection fail");
}
}
void loop() {
// if there are incoming bytes available
// from the server, read them and print them:
while (client.available()) {
char c = client.read();
Serial.write(c);
}
// if the server's disconnected, stop the client:
if (!client.connected()) {
Serial.println();
Serial.println("disconnecting from server.");
client.stop();
// do nothing forevermore:
while(true);
}
}
void printWifiStatus() {
// print the SSID of the network you're attached to:
Serial.print("SSID: ");
Serial.println(WiFi.SSID());
// print your WiFi shield's IP address:
IPAddress ip = WiFi.localIP();
Serial.print("IP Address: ");
Serial.println(ip);
// print the received signal strength:
long rssi = WiFi.RSSI();
Serial.print("signal strength (RSSI):");
Serial.print(rssi);
Serial.println(" dBm");
