title: Is it possible to transfer a file through CoAP?
body: <p>Recently, I am doing a project and I am trying to transfer a json file to the CoAP server. I put some random values in <strong><em>key:value</em></strong> pairs such as:</p>
  
  <pre><code>{
      key1: value1,
      key2: [value21, value22, value23]
  }
  </code></pre>
  
  <p><strong>Questions:</strong></p>
  
  <ul>
  <li>CoAP is pretty much similar to HTTP. So, like HTTP, is it possible to transfer a json file through CoAP using POST/PUT method? If it is possible, what is the recommended directory location to put the uploaded file into the server (<strong>resource</strong> directory)?</li>
  </ul>
  
  <p><strong>Update:</strong></p>
  
  <p>The actual file size is about to 152.8 kB.</p>
