What is included in the AT&T IoT Starter Kit?

The Starter Kit comes with an NXP FRDM-K64F microcontroller board, an Avnet Cellular Shield daughterboard based on WNC’s M14A2A LTE module, a SIM, and associated antennas, power supplies, and connectors. The SIM comes with 300 MB of data and 300 SMS for use over 6 months. Also included with the kit is trial access for 6 months to AT&T’s M2X and Flow.

What is needed to set up the included SIM?

Unlike a consumer device, IoT devices do not automatically configure themselves for connectivity to the network and instead, will need to be properly configured.

Your device may have come pre-configured with a consumer APN that will not work with these SIMs. In order to establish a successful data connection, when you test your device with the SIMs in this kit, please be certain to set your device’s APN name to m2m.com.attz.

No username or password is typically required.

This setting can typically be found in your device’s connection software or network details. If you are unable to set the APN on your device, please contact the device manufacturer for details on how to set an APN on your specific device.

How do I activate my SIMs?

Add the SIM to your Dashboard using the blue + button, then change the SIM Status from “Test Ready” to “Activated”.

What configuration do I need on my device?

The only configuration you need to set on your device is the APN, which should be “m2m.com.attz”. It does not require a user name, password, or port.

Is there a way to add more data to my SIM or purchase additional SIMs for continued testing?

Yes, with the IoT data plan, that process is simple. Set up a new account or upgrade your existing developer account with up to 1,000 SIMs and a data plan that’s tailored to your needs and budget. Please visit iotdataplans.att.com to find our more information.

How does SMS work with the SIM?

AT&T Control Center SIMs can only send and receive SMS messages from other AT&T Control Center SIMs, directly from the AT&T Control Center platform, or through the various SMS APIs available.

How many SMS come with Starter Kits?

You can send 300 SMS with the Starter Kit SIMs (for any of the kits).

Can I send an SMS to the device?

Yes, but maybe not like you’re thinking. The SIMs are on a network dedicated to IoT devices, though it uses the same cellular infrastructure as regular cell phones. They do not have a phone number your can send a text to from your cell phone. You can, however, send an SMS using the RESTful API.

What is the Avnet Cellular Shield?

The Avnet Cellular Shield is a daughterboard that provides cellular connectivity to any microcontroller board with an Arduino R3 expansion slot. The shield is based on a WNC M14A2A cellular connectivity module, and requires an active SIM with a data plan to operate.

Can I use the Avnet Cellular Shield with microcontrollers other than the FRDM-K64F?

Yes, the shield is compatible with any microcontroller board with an Arduino R3 expansion slot or by using the USB connector. However, the sample applications were built for the FRDM board and the ARM mbed IoT Device Platform, and so it’s the easiest to integrate with the shield. Currently, there is no software library for Arduino itself, however. You could implement your own using the AT Command Guide on the Resources page. For using something like a Raspberry Pi, see the guide for doing so on our Quickstart page.

What software is provided to facilitate my development process?

Avnet provides libraries and example programs on mbed that enable the FRDM board to utilize the Cellular Shield for connectivity. From the software running on the devices themselves, to integration with cloud services like M2X and Flow, these examples will help you quickly get started in building your end-to-end IoT solution.

Do I have to use AT&T’s cloud-based IoT services?

No, if you’re an experienced developer and you’d like to use your own cloud-based services, there are no limitations preventing you from doing so. However, if you’re new to the cloud, our examples will walk you through step-by-step how to set up your cloud integration by using AT&T’s M2X and Flow.

Does my Starter Kit SIM support roaming?

At the moment, these SIMs do not support roaming. The SIMs are provisioned to work on the AT&T US network. However, roaming support is currently in the works and will soon be available.

How many MB are in a GB?

For our IoT data plans, 1 gigabyte (GB) = 1024 megabytes (MB). 3 GB = 3072 MB and 5 GB = 5120 MB.

Does it work outside the US?

The M14A2A based shield works in North America, including Mexico and Canada. The data plan, however, only works in the US currently.

Does it come with GPS?

The current kit does not include GPS. We do have a tutorial on how to integrate the inexpensive Xadow GPS v2 module.

Can I access my device remotely?

For the IoT Starter Kit and most devices, the answer is no. For more complex devices you could set up your own VPN tunnel, but we do not provide instructions on this. Each device is given a point-to-point private and dynamic IP address, which allows it to communicate with services on the Internet, but not the other way around.

How can I tell how much data I’ve used?

Use the RESTful API to determine usage.
