Hello
Please help. I modified your code:

#include "ESP8266.h"
#include <ArduinoJson.h>

#define SSID        "net"
#define PASSWORD    "pass"
#define HOST_NAME   "192.168.1.8"
#define HOST_PORT   (8095)

ESP8266 wifi(Serial3);

void setup(void)
{
    Serial.begin(9600);
    Serial.print("setup begin\r\n");

    if (wifi.setOprToStation()) {
        Serial.print("to station ok\r\n");
    } else {
        Serial.print("to station err\r\n");
    }

    if (wifi.joinAP(SSID, PASSWORD)) {
        Serial.print("Join AP success\r\n");

        Serial.print("IP:");
        Serial.println( wifi.getLocalIP().c_str());       
    } else {
        Serial.print("Join AP failure\r\n");
    }

    if (wifi.disableMUX()) {
        Serial.print("single ok\r\n");
    } else {
        Serial.print("single err\r\n");
    }

    Serial.print("setup end\r\n");
}

void loop(void)
{
    uint8_t buffer[1024] = {0};


    if (wifi.createTCP(HOST_NAME, HOST_PORT)) {
        Serial.print("create tcp ok\r\n");
    } else {
        Serial.print("create tcp err\r\n");
    }

    char *hello = "GET /api HTTP/1.1\r\nHost: 192.168.1.8\r\n\r\n";
    wifi.send((const uint8_t*)hello, strlen(hello));

    uint32_t len = wifi.recv(buffer, sizeof(buffer), 10000);
    uint32_t i = 0;
    char json[len];
    if (len > 0 ) {
        //Serial.println("Pobrano:[");
       while(i < len){
         json[i++] = (char)buffer[i];    

        }

    }


      Serial.print(json);

/*      
StaticJsonBuffer<450> jsonBuffer;
  JsonObject& root = jsonBuffer.parseObject(json);

  if (!root.success()) {

Serial.print("blad JSON"); 
    return;
   }
String runningIndex = root["runningIndex"];
Serial.print("runningIndex: ");
Serial.print(runningIndex);
*/
   while(1);

}

monitor serial displays:

{"lowVersion":1,"highVersion":4}

I want to display only:

{"lowVersion":1,"highVersion":4}

I need to read JSON.

Hi..
"//" use this before Serial.print("create tcp ok\r\n");
and
Serial.print("setup begin\r\n");
Serial.print("create tcp ok\r\n");

[rafik73github]

continues to be displayed:

TTP/1.1 200 OK

{"lowVersion":1,"highVersion":4}

but I need only:

{"lowVersion":1,"highVersion":4}

You may need to modify the function recvPkg ?

[chinmoyrick]

its reply your connection done and send data or recived.

[chinmoyrick]

char json[len];

Serial.print(json);

Serial.print("blad JSON");

I think" Serial.print("blad JSON"); " use // before this and check....

[LuizHAP]

chinmoyrick, i don't undestand the change. u can explain some more?

[lenny1972]

you can use strimg.index of and Strig.substring functios to identify and select rhe only part of the replay you need to display/use
