rosbridge counts me as a new client each time I send a message

edit

Hi,

I tried to establish a UDP socket on my windows 10 laptop. I am sending commands from it to RaspberryPi3 which has ROS Kinetic on it.

After creating the socket and sending the message,everytime I send a JSON message rosbridge counts me as a new client. I am sending messages to be published in a topic. I am indicating my message ID but rosbridge keeps counting. What can be the reason?

this is the JSON i am sending (it needs \ because it is written in cpp):

{ "{ \"op\": \"publish\", \"id\": \"metin's laptop\",  \"topic\": \"myTopic\",  \"msg\": \{\"data\": \"hello from metin!\"\} \}" }
