Using AT&T's IoT Dev Kit

In the Zephyr microPlatform update 0.13, we have released support for the AT&T IoT Starter Kit (LTE-M).

With the following instructions, you can start using Zephyr and the IoT Starter Kit with LWM2M in a matter of minutes.

Update an embedded device with LwM2M

OMA Lightweight M2M (LWM2M) offers a firmware object interface for directing client devices to download and apply firmware updates. Using the Zephyr microPlaform and Eclipse’s Leshan Demo Server, this seemingly complex process can be demonstrated in a few easy steps.

To illustrate how a firmware update is delivered via LwM2M, you will make a small change to the Zephyr microPlatform (ZMP) LwM2M sample project which disables the Light Control object. When flashed to an embedded device, the Leshan UI will be missing the “Light Control” portion near the bottom of the client detail page. Once this “bug” is found, you will fix the LwM2M sample, recompile and deliver your updated firmware as an over the air (OTA) update. The new firmware can be confirmed by locating the “Light Control” object in the Leshan UI.
