Hi,
For a while my Arduino GIGA R1 WiFi was working perfect but i've now got a problem were the bootloader always crashes when i'm trying to connect to WiFi. My own script that was always working crashes, but also the example script from the library give the same troubles.
The problem occurs when i use WiFi.begin(ssid, pass);
After a few seconds the red LED starts to blink like this:
My complete code:
/*
Web client
This sketch connects to a website (http://example.com) using the WiFi module.
This example is written for a network using WPA encryption. For
WEP or WPA, change the Wifi.begin() call accordingly.

#include <WiFi.h>

///////please enter your sensitive data in the Secret tab/arduino_secrets.h
char ssid[] = SECRET_SSID; // your network SSID (name)
char pass[] = SECRET_PASS; // 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(93,184,216,34); // IP address for example.com (no DNS)
char server[] = "example.com"; // host name for example.com (using DNS)
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 native USB port only
}
// check for the WiFi module:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("Communication with WiFi module failed!");
// 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 3 seconds for connection:
delay(3000);
}
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 /index.html HTTP/1.1");
client.print("Host: ");
client.println(server);
client.println("Connection: close");
client.println();
}
}
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 board'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");
}
It worked fine until now and suddenly it doesn't anymore. Anyone has a suggestion?
