Several mobile network carriers specify their own LwM2M device management. The LwM2M carrier library facilitates an nRF91 device to connect to the device management servers, regardless of the other actions of the user application. For more information, see the list of applicable carriers, and the Certification and version dependencies subpage.
It is mandatory to include the LwM2M carrier library in any Verizon certified product.
The nRF9160: LwM2M carrier sample demonstrates how to run this library in an application. In addition to this stand-alone sample, the following applications and samples include an overlay file to easily integrate the LwM2M carrier library:
See the Zephyr documentation on Lightweight M2M (LWM2M) if you want to use LwM2M for other purposes.
