title: How to extract raw data from TCP packets using Wireshark
body: <p>Completely new to Wireshark and wondering how to extract the data from the TCP packets which I receive on wireshark.</p>
  
  <p>I am currently using a raspberry pi with grove sensors and getting the values of pressure and temperature. I am sending these values to a server in cloud and it is working. I am using wireshark to trace the packets.</p>
  
  <p>Now I want to extract the data (i.e the pressure value and temperature value) from the packets and store them in a file for further implementation. Is there a way to do it? If yes, then can anyone please explain? It will be helpful.</p>
  
  <p>Thanks.</p>
