The storage module provides a convenience function for reading batch data:
int storage_batch_read(struct storage_data_item *out_item, k_timeout_t timeout);
It reads stored data through the batch interface, handling header parsing and data extraction automatically. All other operations (requesting batch access, session management, etc.) go through zbus messages.
Important
This function should only be called after receiving a STORAGE_BATCH_AVAILABLE message in response to a STORAGE_BATCH_REQUEST.
When done consuming all items, send STORAGE_BATCH_CLOSE with the same session_id.
