Warum verträgt sich die Zeile WiFi.config(config_IP); (Zeile 73) nicht mit der Zeitabfrage.
(Ist momentan auskommentiert)
Hängt sich bei:
Serial.println("\nStarting connection to server...");
Udp.begin(localPort);
komplett auf. Für Hilfe wäre ich dankbar.
Anbei der komplette Code.
Vielen Dank!
Es betrifft diesen Bereich:
// attempt to connect to WiFi network:
while (status != WL_CONNECTED) {
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
//WiFi.config(config_IP); //An der Zeile scheitert Udp.begin
// Connect to WPA/WPA2 network. Change this line if using open or WEP network:
//status = WiFi.begin(config_SSID.c_str(), config_PWD.c_str());
status = WiFi.begin(ssid, pass); //funktioniert
// wait 10 seconds for connection:
delay(10000);
}
Serial.println("Connected to WiFi");
printWifiStatus();
Serial.println("\nStarting connection to server...");
Udp.begin(localPort);
