Simplicity SDK EZSP Reference Guide#

NOTE: This section replaces UG600: Simplicity SDK EZSP Reference Guide. Further updates to this application note will be provided here.

The EmberZNet Serial Protocol (EZSP) defined in this document is the protocol used by a host application processor to interact with the EmberZNet PRO stack running on a Network Co-Processor (NCP). EZSP messages are sent between the host and the NCP over either a Serial Peripheral Interface (SPI) or a Universal Asynchronous Receiver/Transmitter (UART) interface.

This document is up to date with EmberZNet PRO Release 8.1.

Following the release of Zigbee EmberZNet v8, included in Simplicity SDK, several API and type definitions have changed. For more information, visit Renaming Changes in Zigbee.

What's New#

The initial creation of this document is based on UG100. Note that EZSP for Gecko SDK suite (GSDK) releases will continue to be described by UG100. This document applies specifically to EmberZNet versions (8.0 and later) released as part of the Simplicity SDK suite.
