i was trying for days to fix that problem without success

can anybody help please

here's a part of my code

Code: Select all#include <LCD5110_Graph.h>
#include <Adafruit_MLX90614.h>

#define DEVICE_ID "Monitor1"

#define DEBUG true
#define REQ_CODE_ACK 1
#define REQ_CODE_VALUES 2

//84w * 48h

extern uint8_t SmallFont[];   //8h * 6w font

Adafruit_MLX90614 mlx = Adafruit_MLX90614();
int pinLM35 = A0;         //Pin A0 is for LM35
int fsrAnalogPin = A2;    //Pin A2 is for force sensor
int blinkPin = 13;        // Pin 13 is the on-board LED

String mSSID = "LibyaADSL-9a86";    //initial ssid and password
String mPASS = "BYRTPCRJAHPWQ";

//http request code
int service_code;       


//wifi listen variables
String wifiBuf = "";       
char character;
int connectionId = 0 ;

//sensor values
float sensor_mlx, sensor_heart, sensor_lm35;
int sensor_force;

  pinMode(blinkPin,OUTPUT);         // pin that will blink to your heartbeat!
   
  delay(200);
}

//init esp8266

}



/*
