<p>Provides a choice of tcp input connections. Can either be a client - or provide a listening socket.</p>
|
|
<p>The TCP node produces a <i>BUFFER</i> object <b></b>msg.payload</b> and NOT a String. If you need a String then use <i>.toString()</i> on <b>msg.payload</b> in your next function block.</p>
|
|
<p>It also provides <b>msg.fromip</b> of the form ipaddress:port .</p>
|
|
<p>You can select Base64 encoding if you want to make it easy to preserve the complete message as a string.</p>
|
|
<p>In case of disconnection the client trys to reconnect every 10 secs. Topic is optional.</p>
