3.1.6 Persistent Data Server (PDS) Operation

This section captures the power profile of the WLR089 device measured while performing Persistent Data Server (PDS) operations and highlights the profile on the following PDS operations.

  • PDS_Store – Stores a specified and individual MLS attribute into Non-Volatile Memory (NVM)
  • PDS_StoreAll – Stores all the attributes that are registered into PDS at the time of initialization
  • PDS_RestoreAll – Restores all the stored attributes of MLS and helps to resume the operation from the last stored state
  • PDS_DeleteAll – Erases all the stored attribute data of MLS

The PDS is a feature implemented to store the attributes of MLS into NVM and restore and resume the operation after a Reset condition.

The following figures illustrate the profile captured during the PDS_Store, PDS_StoreAll, PDS_RestoreAll and PDS_DeleteAll operations and highlights on the power consumption values during these operations.

The following figure illustrates the PDS store operation.
