Here is my latest test, slightly modified chat example. I also just tested web server example, it too causes my Arduino to lock up 5-15 minutes after a session.
The firmware is the latest from the 1.5.6 beta installer (similar results from v1.05 r2), and my setup is an Uno R3 with the WiFi Shield and nothing else. Help? Thanks much.
#include <SPI.h>
#include <WiFi.h>
char ssid[] = "xxxx"; // your network SSID (name)
char pass[] = "xxxx"; // 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;
WiFiServer server(9001);
boolean alreadyConnected = false; // whether or not the client was connected previously
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);
}
String fv = WiFi.firmwareVersion();
if ( fv != "1.1.0" )
Serial.println("Please upgrade the firmware");
// 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);
}
// start the server:
server.begin();
// you're connected now, so print out the status:
printWifiStatus();
}
int i = 0;
unsigned long time = millis();
void loop() {
// wait for a new client:
WiFiClient client = server.available();
// monitor up time by displaying count of seconds idle
if (!client && (millis() > time + 1000)) {
i++;
time = millis();
Serial.println(i);
}
// when the client sends the first byte, say hello:
if (client) {
i = 0; // reset idle counter
client.flush();
Serial.println("We have a new client");
client.println("Hello, client!");
while(client.connected()){
if (client.available() > 0) {
// read the bytes incoming from the client:
char thisChar = client.read();
// echo the bytes back to the client:
server.write(thisChar);
// echo the bytes to the server as well:
Serial.write(thisChar);
}
}
client.stop();
}
}
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");
