Moin zusammen,
ich betreibe ein Arduino Wifi-shield mit einem Mega2560. An einem PC habe ich ein TP-LINK 300MPS TL-WR802N angeschlossen und es als Acesspoint eingerichtet. Der Arduino erkennt das WLAN-Netzwerk wenn ich das "Scan-Beispiel" hochlade, wenn ich das "Verbindungsbeispiel mit WPA Verschlüsselung" hochlade sucht er nach dem Netzwerk kann sich aber nicht verbinden. Muss ich im Netzwerk noch etwas anpassen oder das Beispiel verändern?
Beste Grüße
Pascas
Wenn Du den Sketch (bitte in Codetags setzen) zeigst, könnten wir evtl. antworten.
Gruß Tommy
Hallo,
ich habe es mit den folgenden beiden Sketchen versucht, SSID und Passwort habe ich natürlich angepasst.
#include <WiFi.h>
char ssid[] = "yourNetwork"; // your network SSID (name)
char pass[] = "12345678"; // your network password
int status = WL_IDLE_STATUS; // the Wifi radio's status
void setup() {
// initialize serial:
Serial.begin(9600);
// attempt to connect using WPA2 encryption:
Serial.println("Attempting to connect to WPA network...");
status = WiFi.begin(ssid, pass);
// if you're not connected, stop here:
if ( status != WL_CONNECTED) {
Serial.println("Couldn't get a wifi connection");
while(true);
}
// if you are connected, print out info about the connection:
else {
Serial.println("Connected to network");
}
}
void loop() {
// do nothing
}
/*
This example connects to an unencrypted Wifi network.
Then it prints the MAC address of the Wifi shield,
the IP address obtained, and other network details.

Das Firmwareupgrade auf 1.1.0 habe ich durchgeführt.
ich habe noch ein Shield von Seeed Studios welches sich mit diesem Sketch sofort mit dem AP verbindet.
#include <SoftwareSerial.h>
#include "WiFly.h"
SoftwareSerial uart(2, 3); // create a serial connection to the WiFi shield TX and RX pins.
WiFly wifly(&uart); // create a WiFly library object using the serial connection to the WiFi shield we created above.
void setup()
{
uart.begin(9600); // start the serial connection to the shield
Serial.begin(9600); // start the Arduino serial monitor window connection
wifly.reset(); // reset the shield
while(wifly.join("mySSID","mySSIDpassword",WIFLY_AUTH_WPA2_PSK) == false)
{
Serial.println("Failed to connect to accesspoint. Will try again.");
}
Serial.println("Connected to access point!");
}
void loop()
{
}
