title: How to send firmware package from LWM2M Leshan server to LWM2M Wakaama client?
body: <p>I have a LwM2M Wakaama client working with a Leshan server. When I try to send a huge hexbinary string via the write option on Package resource for Firmware update object 5, I get the following error message on the client side:</p>
  <blockquote>
  <p>&quot;Block1 NOT IMPLEMENTED&quot;.</p>
  </blockquote>
  <p>I understand that block1 was not implemented on the wakaama client and only block2 was implemented, does anyone know why?</p>
  <p>Also, How can I make firmware update with package resource work with the Leshan Server and Wakaama Client?</p>
  <p>I believe I can either change the Leshan Server to send a request of type BLOCK2 (which I dont know how to do from the limited UI?) or add support for BLOCK1 on Wakaama LWM2M client.</p>
  <p>Has anyone tried this?</p>
