title: What differ CoAP and LwM2M?
body: <p>I study about IoT protocol CoAP, MQTT, LwM2M.</p>
  
  <p>I was able to know a little about CoAP and MQTT.</p>
  
  <p>But I do not know what LwM2M is.</p>
  
  <p>I do not know what's different from CoAP.</p>
  
  <p>I just thought that LwM2M is not a protocol with some format but a system structure using CoAP.</p>
  
  <p>Is that correct?</p>
  
  <p>What is LwM2M and How Can I know more information about LwM2M?</p>
  
  <p>Please someone teach me.</p>
