JCU APIs

The Core Utilities (JCU) provide an easy-to-use interface to simplify the programming of a range of non-network-specific operations. These utilities/modules each have a C function API, which allows a module to be used from a user application. The JCU is supplied in the ZigBee 3.0 SDK.

The JCU modules are outlined below:

• Non-Volatile Memory Manager (NVM): This module handles the storage of context and application data in Non-Volatile Memory (NVM), and the retrieval of this data. It provides a mechanism by which the device can resume operation without loss of continuity following a power loss.

• Low-Power: This module manages the transitions of the device into and out of low-power modes, such as sleep mode.

• Protocol Data Unit Manager (PDUM): This module is concerned with managing memory, as well as inserting data into messages to be transmitted and extracting data from messages that have been received.

Note: The JCU modules are fully described in the DK6 Core Utilities User Guide (JNUG3133).
