UltraSonic Sensor data from Arduino Uno not uploading to Things Speak channel

Using Arduino Programming Questions
1

I am trying to write a code to send my Ultrasonic Sensor data(Hc-SRO4) to my Things Speak channel. I am using an ESP 8266 module for the connection on an Arduino Uno board along with my ultrasonic sensor. I am able to get the ip from the esp but not able to upload my data on my channel.

Here is my Code

#include <SoftwareSerial.h>
#define echoPin 6 // Echo Pin
#define trigPin 7 // Trigger Pin

int maximumRange = 250; // Maximum range needed
int minimumRange = 1; // Minimum range needed
long duration, distance; // Duration used to calculate distance
String apiKey = "0RPVQTXDHBHKILIF";

SoftwareSerial ser(0,1); 


void setup() {                
  
  Serial.begin(9600); 
 
  ser.begin(9600);
 
  pinMode(trigPin, OUTPUT);
 pinMode(echoPin, INPUT);
  
  String wifi="AT+CWJAP=\"myWifi\",\"mypasswd\"";
  ser.println(wifi);
  
}



void loop() {
distance=readDistance();

if(distance>minimumRange && distance < maximumRange){
 Serial.println(distance);
}else{
 Serial.println("Out of range...");
}
 delay(50);
  
  esp_8266();
}

 int readDistance()
{
 digitalWrite(trigPin, LOW); 
 delayMicroseconds(2); 

 digitalWrite(trigPin, HIGH);
 delayMicroseconds(10); 
 
 digitalWrite(trigPin, LOW);
 duration = pulseIn(echoPin, HIGH);
 
 distance = duration/58.2;
 return distance;
}

 
void esp_8266()
{
 
  String cmd = "AT+CIPSTART=\"TCP\",\"";
  cmd += "184.106.153.149"; 
  cmd += "\",80";
  ser.println(cmd);
 
   
  if(ser.find("Error")){
    Serial.println("AT+CIPSTART error");
    return;
  }
  else
  {
    Serial.println("connected");
  }
  
  
  String getStr = "GET /update?api_key=";
  getStr += apiKey;
  getStr +="&field1=";
  getStr += String(distance);
  getStr += "\r\n\r\n";

  
  cmd = "AT+CIPSEND=";
  cmd += String(getStr.length());
  ser.println(cmd);
   Serial.println("siz");
   delay(1000);
   
 if(ser.find(">")){
    ser.print(getStr);
    Serial.println("sent");
  }
  else{
    Serial.println("not sent");
  }
  ser.println("AT+CIPCLOSE");
    
    Serial.println("AT+CIPCLOSE");
   
 
  delay(17000);  
}

Output:
2
connected
siz
not sent
AT+CIPCLOSE

SoftwareSerial ser(0,1);

You can NOT do software serial on the hardware serial pins while doing hardware serial on the pins.

I even tried the (3,4) (4,4) pins , still got the same output :frowning:
