/technologies/internet-of-things/b/blog/posts/secure-mqtt-integration-between-node-red-and-the-things-networkI connected an Arduino MKR WAN 1310 to The Things Network (TTN). Then used Node-RED to connect to the TTN MQTT service and work with the data. Now I&#39;m enabling safe TLS communication to the MQTT. This post is my log of the activity. ima...en-USTelligent Community 12https://community.element14.com/technologies/internet-of-things/b/blog/posts/secure-mqtt-integration-between-node-red-and-the-things-networkSat, 27 Jan 2024 20:36:43 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:ce653cf5-7ba4-4286-95c6-89c84f92f70bDAB1<p>Nice update Jan.</p> <p>I like the secure option, this would be very useful for important data transfer.</p> <p>It would also make spoofing more difficult.</p><img src="https://community.element14.com/aggbug?PostID=27514&AppID=27&AppType=Weblog&ContentType=0" width="1" height="1">https://community.element14.com/technologies/internet-of-things/b/blog/posts/secure-mqtt-integration-between-node-red-and-the-things-networkFri, 26 Jan 2024 13:30:14 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:ce653cf5-7ba4-4286-95c6-89c84f92f70bJan Cumps0<p>&gt; I wrote:&nbsp;</p> <ul> <li> <blockquote>ideally also a client cert and private key, but I haven&#39;t found out yet how to generate or get one for this chain.</blockquote> </li> </ul> <p></p> <p>This is no longer true.
