Title
Failure to update BT Mesh Replay Protection List
Summary
A bug exists in the API, mesh_node_power_off(), which fails to copy the contents of the Replay Protection
List (RPL) from RAM to NVM before powering down, resulting in the ability to replay unsaved messages. Note that as of June 2024, the Gecko SDK was renamed to the Simplicity SDK, and the versioning scheme
was changed from Gecko SDK vX.Y.Z to Simplicity SDK YYYY.MM.Patch#.

Title
Failure to update BT Mesh Replay Protection List
Summary
A bug exists in the API, mesh_node_power_off(), which fails to copy the contents of the Replay Protection
List (RPL) from RAM to NVM before powering down, resulting in the ability to replay unsaved messages. Note that as of June 2024, the Gecko SDK was renamed to the Simplicity SDK, and the versioning scheme
was changed from Gecko SDK vX.Y.Z to Simplicity SDK YYYY.MM.Patch#.
