This is an overview for using both the PubNub Arduino SDK and PubNub MQTT gateway to send and receive data with two common WiFi modules included on Arduino-compatible development boards.
PubNub provides a robust and global messaging infrastructure that can transmit data in under 0.25 seconds anywhere in the world. This is ideal for instant updates from sensors or triggering a smart device action for instance. With a 99.999% SLA on all its services, IoT data is transmitted reliably. PubNub also supports over 70 SDKs and has features like mobile push notifications and Project EON that you can use for monitoring. Sensor reading out of range? Get a notification.
With MQTT specifically, PubNub’s MQTT gateway makes it easy to switch to PubNub as your MQTT broker. You can use any MQTT client or library that supports MQTT 3.1 or newer.
Lastly, PubNub offers a serverless environment to execute functions on messages as they route through the PubNub Network. You can incorporate logic like:
You may want to commit to one connection method over the other after considering the following:
First, download and install the latest Arduino IDE.
Next, sign up for a PubNub account. Once you sign up, you can get your unique PubNub keys from the PubNub Admin Dashboard. PubNub is always free, up to 1 million real-time transactions per month (more than enough for R&D).
