Already Arduino IDE for ESP developement, so we will be happy if pubnub expert will provide library for Arduino IDE(ESP8266 developement).

Code: Select all

String url = "http://pubsub.pubnub.com/publish/demo/demo/0/rkgtest/0/%22Hello%20World%22";
  
  Serial.print("Requesting URL: ");
  Serial.println(url);
  
  // This will send the request to the serveg
  client.print(String("GET ") + url  + " HTTP/1.1\r\n" +
               "Host: " + host + "\r\n" + 
               "Connection: Keep-Alive\r\n\r\n");
  delay(10);

- Sat Aug 01, 2015 9:17 am #24766 You need to split url into 2 parts, the server url and the requested path.
So, "http://pubsub.pubnub.com" pass to the client.connect() function,
and "/publish/demo/demo/0/rkgtest/0/%22Hello%20World%22" to client.print() for the request.

- Sat Aug 01, 2015 11:05 am #24767 What is it "HTTP/1.1 400 Bad Request" ? -> 406 or 418.
Hyper Text Coffee Pot Control Protocol (HTCPCP/1.0) - RFC 2324,
http://www.rfc-editor.org/rfc/rfc2324.txt
RFC 7168 extended HTCPCP to fully handle teapots...

https://en.wikipedia.org/wiki/Hyper_Tex ... l_Protocol
Arduino not support HTCPCP :?:
