Hi,
I am using a wifi shield on the due, I have arduino 1.5.2 running on my system. I am trying to change my ip address using WiFi.config() after WiFi.begin().
However, when I compile I get this error: 'class WiFiClass' has no member named 'config'
I used this link as reference: WiFi - Arduino Reference
I am wondering why I cant use this function when it has been documented. Any help is appreciated.
Warm Regards,
v
You need to post your code and the real error message. Most likely your using the wrong parameter types.
Mark
IPAddress ip(192, 168, 13, 110);
WiFiServer server(80); // create a server at port 80
//-----------------------------------WIFI STUFF--------------------
char ssid[] = "mytestnetwork"; // your network SSID (name)
char pass[] = "somepassword"; // your network password
void setup() {
Serial.begin(9600); // for diagnostics
if (WiFi.status() == WL_NO_SHIELD)
{
Serial.println("WiFi shield not present");
// don't continue:
while(true);
}
WiFi.begin(ssid, pass); // initialize WiFi device
Serial.println("test1");
WiFi.config(ip);
delay(10000);
printWifiData();
server.begin(); // start to listen for clients
pinMode(inPin, INPUT);
pinMode(inPin2, INPUT);
pinMode(inPin3, INPUT);
pinMode(motorPin, OUTPUT);
neck.attach(24);
neck.writeMicroseconds(neck_pos_1);
delay(1000);
neck.writeMicroseconds(neck_pos_3);
delay(1000);
//client = server.available(); // try to get client <move this to setup, create it in such a way that in the loop it will ignore if client is already connected>
digitalWrite(motorPin, LOW);
}
The error message says that there is no member called config in the wifi class.
Thats what i dont understand
No that's NOT WHAT YOUR ERROR MESSAGES SAY.
You have no include for the WiFi class.
Copy and paste your error messages.

Error Message is:
test_wifi_using_http_server.ino: In function ‘void setup()’:
test_wifi_using_http_server:55: error: ‘class WiFiClass’ has no member named ‘config’
Why do you assume that the WiFiClass does have a member named config? It does in 1.5.5, but that may not be true in 1.5.2. My version of 1.5.2 doesn't even have a WiFi library.
