Avnet’s AT&T IoT Starter Kit Powered by AWS enables designers to easily develop and prototype cellular connected IoT devices utilizing AT&T’s 4G LTE network. The kit includes all the elements required to collect sensor data, connect to the AT&T network, and utilize Amazon Web Services for the management, storage, and analytics of a connected IoT device.
The Starter Kit features a two board solution comprised of a microcontroller-based development board and a pluggable, cellular connectivity daughter card. NXP’s Freedom FRDM-K64F microcontroller carrier board acts as the main host processor, providing an Arduino™ compatible R3 expansion slot. The Avnet created 4G LTE cellular shield plugs into the Arduino R3 slot, forming a small 3.25” x 2” x 1” two board “sandwich”. The FRDM-K64F board contains a Kinetis K64F microcontroller, based on an ARM® Cortex®-M4 MCU running at 120 MHz, with 1MB Flash memory, 256 KB RAM, Ethernet port, USB port, microSD card slot, and a 6-axis digital accelerometer and magnetometer. The 4G LTE cellular shield is built around the low-cost Wistron NeWeb Corp. (WNC) M14A2A LTE Cat-1 modem module. The shield supports primary and diversity external antenna connections through two onboard SMA connectors, a 3FF microSIM connector, a temperature and humidity sensor, and multiple serial link options to the host controller.
Application development is supported by AT&T Control Center and AT&T’s IoT Platforms: M2X Data Services and Flow Designer, which provide a scalable, reliable and highly secure environment for IoT-focused solutions. Additional cloud services from industry partners are also available, including a direct connection to Amazon’s AWS IoT service. The hardware platform is enabled for ARM® mbed™, allowing for development in a cloud-based environment, or in a locally supported environment through either the Open Source SDA or JTAG connection to the baseboard.
The kit includes a Quick Start Card to help get the kit up and going, as well as talking to AWS IoT.
IMPORTANT: DO NOT USE THE K64F WITH WINDOWS™ 8/10 WITH STORAGE SERVICES ENABLED! DISABLE WINDOWS™ STORAGE SERVICES ON WINDOWS™ 8/10 BEFORE PLUGGING IN K64F TO A PC!!!
Explanation: A bug in older versions of the ARM™ bootloader firmware can cause the K64F board to have corrupted flash and become unusable until a JTAG device is used to reprogram. Clearer instructions are being constructed and will be made available at a future date!
Once NXP™ version 0243 (or later) K64F firmwares (BOTH bootloader and DAPLink must be upgraded) are programmed into the K64F, it should be safe to use Windows™ 8/10 with or without Storage Spaces enabled.
Workarounds: 1) Do not use Windows™ 8/10 with firmware older than 0243. 2) Disable Windows™ Storage Services before plugging in the K64F board. 3) Upgrade the firmware to the latest on the NXP™ website with Windows™ 7 before using Windows™ 8/10 if you are not able or want to disable windows storage services.
