AT&T Cellular IoT Starter Kit (1st Generation)

Avnet’s AT&T Cellular IoT Starter Kit 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 various cloud 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 carrier 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”.

Application development is supported by AT&T’s M2X Data Services and Flow Designer, which provides a scalable, reliable and highly secure environment for IoT-focused solutions. Additional cloud services from industry partners are also available. 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.

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.  For more info see: https://os.mbed.com/blog/entry/DAPLink-bootloader-update/

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 Services 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.

Note! The LTE Cat-1 version of this IoT Starter Kit is no longer available for purchase. It has been replaced by LTE Cat-4 and LTE-M alternatives: 
 

 LTE Cat-4:  AT&T IoT Starter Kit (2nd Generation)

 LTE Cat-M:  AT&T IoT Starter Kit (LTE-M, K64)

 LTE Cat-M:  AT&T IoT Starter Kit (LTE-M, STM32L4)
