This article will show you how to connect "The Things Network V3" and "AWS IoT Core".

1. TTN Settings

• Select the application to connect from TTN, and select "AWS IoT" from "Integrations".
• Then click on the "Deployment Guide".

• Scroll down.
• For "Select your AWS region", select your region.

• Creating the stack will take a few minutes.

3. Set up with AWS IoT Core

• Log in to the aws IoT Core.
• And if you check "Things", you can see that a new device has been added.

• Let's check if the data can be obtained.
• Enter "lorawan / #" in "MQTT test client".

• After waiting for a while, the data will be earned.

• However, this alone is not enough to extract only the variables you want.
• Let's add a rule for the data format.
• I use a distance sensor, so I try to get only the distance.

• Edit the SQL statement.

• These are the SQL statements I used.

SELECT end_device_ids.device_id AS device, received_at AS r_date, uplink_message.decoded_payload.distance AS distance FROM 'lorawan/A840414/uplink' WHERE uplink_message.decoded_payload.distance > 20
