IoT Starter Kit Powered by AWS Demo
This program demonstrates the AT&T IoT Starter Kit sending data directly into AWS IoT. It's explained and used in the Getting Started with the IoT Starter Kit Powered by AWS on starterkit.att.com.
What's required
- AT&T IoT LTE Add-on (also known as the Cellular Shield)
- NXP K64F - for programming
- microSD card - used to store your AWS security credentials
- AWS account
- Python, locally installed
If you don't already have an IoT Starter Kit, you can purchase a kit here. The IoT Starter Kit Powered by AWS includes the LTE cellular shield, K64F, and a microSD card.
