nRF9160: LwM2M carrier¶
The LwM2M carrier sample demonstrates how to run the LwM2M carrier library (liblwm2m_carrier) in an application in order to connect to the operator LwM2M network.
The following development board:
nRF9160 DK board (PCA10090) - see Working with nRF9160
The sample is configured to compile and run as a non-secure application on nRF91’s Cortex-M33. Therefore, it automatically includes the nRF9160: Secure Partition Manager that prepares the required peripherals to be available for the application.
Building and running¶
This sample can be found under
samples/nrf9160/lwm2m_carrier in the nRF Connect SDK folder structure.
The sample is built as a non-secure firmware image for the nrf9160_pca10090ns board. Because of this, it automatically includes the nRF9160: Secure Partition Manager.
See Building and programming a sample application for information about how to build and program the application.
After programming the sample and all prerequisites to the board, test it by performing the following steps:
Connect the USB cable and power on or reset your nRF9160 DK.
Open a terminal emulator and observe that the kit prints the following information:
LWM2M Carrier library sample.
Observe that the application receives events from the LwM2M carrier library via the registered event handler.
Bootstrapping can take several minutes.
This is expected and dependent on the availability of the LTE link.
During boostrap, several
LWM2M_CARRIER_EVENT_DISCONNECT events are printed.
This is expected and is part of the bootstrapping procedure.
