Modem library integration layer

The Modem library integration layer handles the integration of the Modem library into nRF Connect SDK. The integration layer is constituted by the library wrapper and functionalities like socket offloading, OS abstraction, memory reservation by the Partition manager or devicetree, handling modem traces, and diagnostics.

Note

The Partition Manager is a component in the nRF Connect SDK and is responsible for handling the memory partitioning at build time.

This functionality is in the process of being deprecated and replaced by Zephyr’s default devicetree-based memory partitioning. It is recommended that all new designs using Nordic devices are to be built with DTS instead of Partition Manager. Partition Manager will be removed from the nRF Connect SDK by the end of 2026 from the main branch.
