Thanks a lot!

I am basically testing the example wificlient, and modified some lines to connect to my local server, and after some times it crushed with displaying the below error log, i appreciate any help, thank you, the code and the log is here below



#include <ESP8266WiFi.h>

const char* ssid = "****";
const char* password = "******";

const char* host = "******";
const char* streamId = "....................";
const char* privateKey = "....................";

void setup() {
Serial.begin(115200);
delay(10);

// We start by connecting to a WiFi network

Serial.println();
Serial.println();
Serial.print("Connecting to ");
Serial.println(ssid);

WiFi.begin(ssid, password);

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}

Serial.println("");
Serial.println("WiFi connected");
Serial.println("IP address: ");
Serial.println(WiFi.localIP());
}

int value = 0;

void loop() {
// delay(5000);
++value;

Serial.print("connecting to ");
Serial.println(host);

// Use WiFiClient class to create TCP connections
WiFiClient client;
const int httpPort = 6065;
if (!client.connect(host, httpPort)) {
Serial.println("connection failed");
return;
}

// We now create a URI for the request
client.print("hello");
client.stop();
}

- Sun Jan 22, 2017 3:49 am #61340 Hello alemlishar,

I tried your code and yes, it crashes after a while with watchdog. I tested your code with port 80 acessing my webserver. Possibly it has something to do with the number of tcp-connections (TIME-WAIT), we are opening connections very fast.
However, the reason for a watchdog is unclear for me ...

friendly regards
Henning

- Sun Jan 22, 2017 6:47 pm #61391 Hello Henning,

Basically it works for the first hundreds connection,

i tried to open the connection (Wificlient) inside setup and use that connection for the next connection in the draw, but it wouldn't allow me, in some forum its suggested to raise the voltage to more than 3.3V but that didn't help me though what would you suggest me please? i am using it for my thesis project,

Regards,
