I am trying to get the MQTT gateway to work.  I have followed the instruction and I can ping the gateway, but I cannot connect.  I know this has been discussed and I search the form, but none of the answers work for me.  As the labels on the contact of the W5100 differ from what is on mysensor website, I wanted to check to make sure I was connect everything correct (Mysensor documentation-W5100).</p>
<ol>
<li>GRD=GRD   I know this is correct</li>
<li>VCC=V+5    This is supposed to be connected to 3.3 v, but it only works when connect to 5V  (I assume that is why change the label to (v+5)</li>
<li>SCK=SOK???</li>
<li>MISO/SO=MI???</li>
<li>MOSI/SI=MO??</li>
<li>SS/CS=NSS???<br />
Any help would be appreciated.<br />
Thanks</li>
</ol>
