There, update CloudWatch Logs to turn it on, probably with the '*Log level' of 'Debug (most verbose)'. Select the 'Gear' 'Settings' option from the left pane. Do not close this browser tab you'll want it to eventually verify your ESP8266 is subscribed. Of course, it's just an echo chamber - there are no other things to communicate with, so you're alone with the topic right now.ĭon't despair, we'll get something to listen soon - but for now let's set up debugging in case something goes wrong with IoT during the next steps. You can test subscribing to the topic straight from the test console try publishing a message now and you should see it appear on the same screen. In the 'Subscribe to a Topic' field, enter the topic 'twilio' (lowercase, one word) with a 'Quality of Service' of 0. Subscribing to the 'twilio' MQTT Topicīack in AWS IoT, click the 'Test' subheading in the left pane. We'll eventually use those credentials on our ESP8266 to connect to AWS IoT.Īnd now you've got an IoT IAM User for your thing to use! Navigate back to the IoT Console. One more thing - download the CSV with the user credentials from the success screen. This guide requires numbers with SMS and optionally MMS capabilities. In 'Capabilities', you'll see the functions available with your current Twilio phone numbers. Second, select the hash tag/Phone Numbers ('#') section on the left side, and navigate to your current active numbers. Find or Purchase a SMS (and MMS) Capable Numberįor this demo, you'll require a SMS and MMS enabled number you either purchase or already own.įirst, enter the Twilio Console. You'll need to enter values from the console in a few places, and you will also need details on a purchased number - so keep a tab handy. Sound like a trip? Fall into the newly conversant Internet of Things! Sign Into - or Sign Up For - a Twilio AccountĮither create a new Twilio account (sign up for a free Twilio trial here), or sign into your existing Twilio account. We'll demonstrate connecting to AWS IoT with MQTT over Websockets, publishing to an MQTT topic from the ESP8266, and triggering Lambda functions from certain messages published on the MQTT topic. We're going to make an Espressif ESP8266 send a SMS or MMS message with Twilio using Amazon AWS IoT and Lambda. Let's make the Internet of Things a little more outgoing today.
