ESP8266 Community Forum

- Sun Apr 09, 2017 12:21 pm #64769 hi to all, i am working on a project that in it i need to send some file over wifi from my computer to my micro and i decide to use esp8266 in order to done that. i use below code for my esp8266 to recive file and redirect it to uart port :

Code: Select all#include <ESP8266WiFi.h>

uint8_t data = 0;

WiFiServer server(8888);
int counter = 0;
void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);

  WiFi.softAP("akbar","akbar11041");

  server.begin();
 
}

void loop() {
   // put your main code here, to run repeatedly:
   WiFiClient con = server.available();
   if(con)
   {
      Serial.println("new connection");
      counter = 0;
      while(con.connected())
      {
        if(con.available())
        {
          counter += con.read(&data,1);
         
          Serial.print(data);
          Serial.println();
        }
      }
      Serial.println("Connection closed");
      Serial.println("number of items :");
      Serial.println(counter);
      con.stop();
   }
}


and use below python code for sending file :

Code: Select allimport socket
import time



fl = open("3.dat","rb")
data = fl.read()
con = socket.socket(socket.AF_INET,socket.SOCK_STREAM)
con.connect(("192.168.4.1",8888))
print(con.send(data))
fl.close()


but i have a problem, as you can see i send every byte that i receive to Serial port, but for example when i sent a file that has 768000 byte i only receive 5000 byte of that file in esp and also in uart.
now can any one help me to solve that, it offend me for tow day.

For those range of hobbies like me, problem solved by adding below line to my code:

Code: Select allWiFi.mode(WIFI_AP);


And after that everything will be ok
