Sample code to retrive last value from Thinkspeak using ESP8266 | ESP Wi-Fi | Forum

Hi,

I am new with Arduino & esp8266 and using the below code to upload data to ThinkSpeak. Everything works fine, but now I want to retrieve some data back from ThinkSpeak. Can some one help in developing the code for retrieval?

From what I am checking, I have to use the above GET string to get the fields data. But I don't know how to create the request string.

Help would be appreciated. Thanks

// Uploading data to Thinkspeak<br />uploadData() {
String apiKey = "ESDS8678890SDDS";
String myData = "45.5"; // example of data to send
if (espClient.connect(server,80)) { 
String postStr = apiKey; 
postStr +="&amp;field1=";
postStr += String(myData);
postStr += "

";

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

");
espClient.print(postStr);
Serial.print(postStr);
Serial.print("My Data: ");
Serial.print(myData);
Serial.print("
");
}
espClient.stop();
}<br /><br />
