the ""{\"pwr\":\"off\"}\r\n"" should come after all the headers and the newline (\r\n), not in between the headers.

Reeshma give a look to the HTTP protocol specs:
https://www.w3.org/Protocols/rfc2616/rfc2616-sec5.html

Code: Select all

Request       = Request-Line              ; Section 5.1
                        *(( general-header        ; Section 4.5
                         | request-header         ; Section 5.3
                         | entity-header ) CRLF)  ; Section 7.1
                        CRLF
                        [ message-body ]          ; Section 4.3
you have to put all the headers first, then add a blank line ("CRLF") and after that line add your body {\"pwr\":\"off\"}

Hi

use a tool like Fiddler or some browser extensions to "sniff" the real request the browser send and implement the same in your code
