Release notes

CMi6110 2.3.1

Release date: 2024-03-18

Configuration changes: No changes in 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 CMi6110. 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.
