Wifly shield stop problem

Wireless & IoT

Hello,

I’ve been having a problem of Wifly shield. The connection seems stopping after some minutes until I manually reset the arduino.

The code is like this:

#include "WiFly.h"
#include "Credentials.h"
Client client("google.com", 80);

boolean animation= false;

String number;
int skipCount= 0;
int numSkipLines=7;
int page=0;

void setup() {
  Serial.begin(9600);
  wiflySetup();
}


void wiflySetup()
{
  WiFly.begin();

  if (!WiFly.join(ssid, passphrase)) {
    Serial.println("Association failed.");
    while (1) {
      // Hang on failure.
    }
  }
  Serial.println("connecting...");
  wiflyUpdate();
}



void loop()
{
  if(!animation){
    wiflyLoop();
    delay(1);
  }
  else{
//    segDisplay();  // *** I control segments/matrix LEDs with the data from wifi
//    matrixDisplay(); //*** I comment out these to debug but the connection will still be lost 
  }
}



void wiflyLoop()
{
    if (client.available()) {
    char c = client.read();
    Serial.print(c);
  }
  
  if (!client.connected())
  {
    Serial.println("unconnected - will be updated");
    client.stop();
    skipCount=0;
    delay(1000);     
    wiflyUpdate();
  }
}



void wiflyUpdate()
{
  client.flush();
  Serial.flush();
  Serial.println("updating...");

  if (client.connect()) {
    Serial.println("connected");
    client.println("GET /search?q=arduino HTTP/1.0");
    client.println();
  } 
  else
  {
    Serial.println("connection failed");
  }
}

When it stops, it usually stops just after it prints “updating…” in the methods of “wiflyUpdate()”.

When I add LED controls (segDisplay() or matrixDisplay()) it stops even earlier than when I don’t use them. When I run just the code above it will run over an hour but when I run with the code controling LEDs, it sometime stops within 3 mins.

(In both case, it will stop anyway.) Is this something for memories…?

Could someone give me any suggestion how to solve the problem? I will really appreciate any info.

Thanks in advance,
