Release notes
Release date: 2024-03-18
Configuration changes: No changed configuration parameters.
Integration considerations: Object versions for 33905 and 33906 changed due to changes in definitions/descriptions, see ID MCM-6359 and MCM-6214 below.
Background: This release mainly fixes an issue related to LwM2M send, detected in the previous firmware release of CMi6160. If not using the LwM2M send feature, devices are operating as they are intended to do. In addition to adding some general improvements and fixing some bugs, it also adds the possibility to manually configure PLMN using NFC.

Configuration changes:
-
Added Bootstrap URI as alternative to bootstrap IP
-
Added Manual PLMN with staging for setting PLMN in device
-

Notes New LwM2M object version set for /33906/x/x/ (MCM Config)
Background: This new firmware comes with several new features improving the overall performance of the CMi6160, see list of implemented features below. Please note that the new firmware name is 1.3.0, replacing 1.1.0. To harmonize the naming of products using the Elvaco NB-IoT platform, the sequentially correct naming, 1.2.0, has been skipped intentionally.
