Introduction
This guide provides an overview of the Avnet AT&T Cellular IoT Starter Kit hardware and
software. The guide includes steps that allow you to quickly begin using the kit. The example
software lets you take measurements using various sensors and send the values to the AT&T
M2X/Flow server. Commands, in the form of JSON strings, are sent back to the IoT Starter Kit
from the cloud and instruct the device to control on-board components such as the user LED.
The IoT Starter Kit consists of a hardware platform comprised of an NXP FRDM-K64F single-
board computer (SBC) and an Avnet Arduino-compatible WNC Cellular modem shield mounted
on top. The WNC modem sends/receives data via cellular data link back to the AT&T M2X/Flow
website. System data flow is shown below.
