ESP8266 Community Forum

- Tue Apr 07, 2015 10:22 am #13764 Hi,

I am trying to make a remote serial terminal using the ESP8266. Unfortunately I am new to both the Arduino IDE and ESP8266.

With the below code (vith my ssid and password added in correctly), when I try to connected to the ESP via Telnet, putty disconnects right await like nothing is listening on port 23.

Any help would be much appreciated.

Thx

Code: Select all#include <ESP8266WiFi.h>

const char* ssid = "your-ssid";
const char* password = "your-password";
bool flag_flushed = false;

// Create an instance of the server
// specify the port to listen on as an argument
WiFiServer server(23);

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

  // prepare GPIO2
  pinMode(2, OUTPUT);
  digitalWrite(2, 0);
 
  // Connect to 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");
 
  // Start the server
  server.begin();
  Serial.println("Server started");

  // Print the IP address
  Serial.println(WiFi.localIP());
}

void loop() {
 
 
  // Check if a client has connected
  WiFiClient client = server.available();
  if (!client) {
    return;
  }

  if (!flag_flushed)
  {
    client.flush();
    flag_flushed = true;
  }
 
  if (client.available() > 0)
  {
    char byteread = client.read();
    Serial.write(byteread);
  }
  if (Serial.available() > 0)
  {
    char byteread = Serial.read();
    client.write(byteread);   
  }
}

Anyone else know of any project that does what i'm looking for?

- Mon Oct 17, 2016 10:23 am #56648 There is ESP-LINK project, which is a bit more complex, but it will fill you needs.

- Mon Oct 17, 2016 10:44 am #56649 Thanks martinayotte I found that just after i posted this!, am i correct in thinking it's not initially uploaded via arduino ide? if not do you know of another similar system that i can just upload through the arduino ide or do i have to suck it up and do it using another tool??

Thanks for your initial reply and any further insights
