The recording to Thingspeak suddenly stopped working. | ThingSpeak API | Forum

Hi Vinod, Still I am facing the error, Not updated to thinkspeak, even after changes made as per your suggestion.
One thing i didn't do is, i am not using "thinkspeak.h" library. instead i am using
what to change here.

here is my code

#include "DHTesp.h"
#include
#include
DHTesp dht;

String apiKey = "88888888888888";
const char* ssid = "******";
const char* pass = "************";
const char* server = "api.thingspeak.com";
float humidity = dht.getHumidity();
float temperature = dht.getTemperature();

unsigned long previousMillis = 0;
const long interval = 2000;
WiFiClient client;

void setup()
{

previousMillis = millis();

Serial.begin(9600);
Serial.println();
Serial.println("Status\tHumidity (%)\tTemperature (C)\t(F)");
dht.setup(5, DHTesp::DHT22);

Serial.print("Connecting to: ");
Serial.println(ssid);

WiFi.begin(ssid, pass);

while (WiFi.status() != WL_CONNECTED)
{
delay(100);
Serial.print("*");
}
Serial.println("");
Serial.println("***WiFi connected***");

}

void loop()
{
float humidity = dht.getHumidity();
float temperature = dht.getTemperature();

if ((millis () - previousMillis) >= interval) {

if(temperature >= 20)
{
Serial.println("10secs");
cloud();

previousMillis = millis();

}
}
}

void cloud()
{
float humidity = dht.getHumidity();
float temperature = dht.getTemperature();

if (client.connect(server,80)) // "184.106.153.149" or api.thingspeak.com
{
//String sendData = apiKey+"&field1="+String(temperature)+"

";
//String sendData = apiKey+"&field2="+String(humidity)+"

";
String sendData = apiKey;
sendData +="&field1=";
sendData += String(temperature);
sendData +="&field2=";
sendData += String(humidity);
sendData += "

";

//Serial.println(sendData);

client.print("POST /update HTTP/1.1
");
client.print("Host: api.thingspeak.com
");
client.print("Connection: close
");
client.print("X-THINGSPEAKAPIKEY: "+apiKey+"
");
client.print("Content-Type: application/x-www-form-urlencoded
");
client.print("Content-Length: ");
//client.print(sendData.length());
client.print(sendData.length());
client.print("

");
client.print(sendData);

Serial.print("temp: ");
Serial.print(temperature);
Serial.print("Humi: ");
Serial.print(humidity);
Serial.println("deg C. Connecting to Thingspeak..");
}
delay(500);
client.stop();

Serial.println("Sending....");

delay(10000);
}

Thanks, the above code itself working, after increasing the delay(500) and i used delay as delay(1000) before client.stop().

Same code, i didn't use thinkspeak.h

Hi, i am having a similar problem and tried adding the delay to no avail...

my code was working perfectly fine 6 days ago and it stopped working all of a sudden. i didnt change the coding also...

Serial.println(F("Preparing Thingspeak readings"));

if (client.connect(serverThingspeak, 80))
{
String postStr = apiKeyThingspeak1;
postStr += "&field1=";
postStr += String(t);
postStr += "&field2=";
postStr += String(h);
postStr += "&field3=";
postStr += String(p);
postStr += "&field4=";
postStr += String(r);
postStr += "&field5=";
postStr += String(slp);
postStr += "&field6=";
postStr += String(ba);
postStr += "

";

client.print("POST /update HTTP/1.1
");
client.print("Host: api.thingspeak.com
");
client.print("Connection: close
");
client.print("X-THINGSPEAKAPIKEY: " + apiKeyThingspeak1 + "
");
client.print("Content-Type: application/x-www-form-urlencoded
");
client.print("Content-Length: ");
client.print(postStr.length());
client.print("

");
client.print(postStr);
Serial.println(F("Just uploaded to Thingspeak Channel ID: 1020683"));
