Shiftr has libraries for various platforms including Arduino and Processing that make it very easy to code MQTT Clients.

https://www.shiftr.io/

=SHIFTR ONLINE=

To code a Proccessing Client we use Shiftr's MQTT library for Processing.

==Install Library==
Sketch --> Import Library --> Add Library --> filter: "MQTT"
install "MQTT library for Processing based on the Eclipse Paho project by Joel Gaehwiller"

==Open Example==
File --> Examples --> MQTT --> "PublishSubscribe"

The following line of code connects you to the online Shiftr Broker's public namespace called "try" with the Client ID "processing".

client.connect("mqtt://public:public@public.cloud.shiftr.io", "processing");

<em>Notes:
Make sure the URL in your code is the same as the current URL shown on the public namespace website:

"mqtt://public:public@public.cloud.shiftr.io"

If you are using your own namespace, make sure you edit the URL to include:

name_of_your_instance

token_secret

url_of_your_instance

"mqtt://name_of_your_instance:token_secret@url_of_your_instance.cloud.shiftr.io"

if you need to use a different port number other than the default 1883 (for example 2883), you can specify it like this:

"mqtt://name_of_your_instance:token_secret@url_of_your_instance.cloud.shiftr.io:2883"
</em>

=SHIFTR Desktop App=

Download the Shiftr MQTT library (see above).

Open the Shiftr MQTT example (see above).

Insert your IP address instead of the Shiftr URL:

client.connect("mqtt://192.168.0.9", "processing”);

if you need to use a different port number other than the default 1883 (for example 2883), you can specify it like this:

client.connect("mqtt://192.168.0.9:2883", "processing”);
