How to get LwM2M carrier library version integrated in NCS.

Chetan Kale

Hello, 

I am using LwM2M library in my project and I want to check what version I am using of LwM2M carrier library. Please correct me if I am wrong, is according to below screenshot should I assume that the nRF SDK connect version has pre-installed LwM2M carrier library with specific revisions ? 

Example: nRF SDK Connect 1.7.0 has pre-installed LwM2M carrier Library 0.20.1 OR nRF SDK Connect 2.0.0 has pre-installed LwM2M carrier Library 0.30.0

NCS version : 1.7.0

Modem Firmware version: 1.3.1

Device Revision : NRF9160_xxAA_REV2

Board Version : PCA10090

Thank you !

Regards,

Chetan

    Hi Chetan,

    A table that you mentioned specifies a version of NCS that corresponds to a specific version of LWM2M carrier library. 
    Some operators require LWM2M carrier library.  Compatibility matrix shows the compatibility between certain nRF Connect SDK (NCS) version and modem firmware version. If the operator requires LWM2M library, it must be included in the application for successful certification with the carrier. In order to include carrier library in the application, the application would need to be implemented with API of the library. You can read more about application integration in the documentation.

    Hi Dejans,

    So based on above explanation, I no need to worry about the LwM2M carrier Library version as they are already available with required version inside the NCS directory. Am I right ?

    Also please clarify my doubt that is nRF SDK connect and NCS meaning is same in that compatibility matrix for verizon. 

    Ex. If my dev kit is on Modem Fw version 1.3.1 then I should use NCS or nRF SDK connect version 2.0.0 ?

    Thank you !

    Regards,

    Hi Chetan,

    LWM2M carrier library is included in NCS. If you are looking for Verizon certification, you need to take care that you use specific NCS version and modem firmware version as they are specified in the compatibility matrix.

    NCS is abbreviation for nRF Connect SDK.

    Based on the compatibility matrix, modem firmware v1.3.1 should be used together with NCS v2.0.0.

    Best regards,
    Dejan
