BeeKit™ Definitions
A codebase contains all the information that is required for BeeKit to interact with the user and create a project for a specific communication stack. Freescale provides a codebase in the form of:
− A database containing the embedded software component source files (platform components, applications, etc.) and pre-compiled libraries (SMAC, MAC, or BeeStack)
− Configuration files that hold information about the organization of the embedded software components, their configurable parameters and features, and the BeeKitGUI information
Freescale provides each codebase. The user does not modify it, but uses BeeKit to generate stack-based directory structures external to the codebase.
A solution contains one or more BeeKit projects drawn from a single codebase.
A project in BeeKit is a complete collection of attributes that define a stack and application configuration for a particular target platform.
A project exported from BeeKit consists of assembled codebase components (source files, libraries) and an XML file (CW) or EWP file (EWARM) that describes the project.

The need for a new wireless network
• We are entering a new era of connected products
− There needs to be a low power mesh network in
addition to Wi-Fi in your home
• We wanted to use an existing wireless mesh
protocol
− But none fit our requirements well enough
− Some came close but were not suitable for homes and
CE products
• After talking with other companies it was clear that
they shared the same concerns
− So we started working on a new wireless mesh
protocol. One that was built on existing standards but
legacy-free
− Working as a group of companies to help make
Thread better
Requirements:New wireless home network
✔ Low power
✔ Resilient (mesh)
✔ IP-based
✔ Open protocol

ZigBee Alliance and Thread Group Collaborate to Aid
Development of Connected Home Products
Agreement Opens Doors for ZigBee Cluster Library Application Protocol to Run on
Thread Networks
San Ramon, Calif. – April 2, 2015 – The ZigBee Alliance (www.ZigBee.org) and the
Thread Group (www.threadgroup.org) today announced they are collaborating to enable
the ZigBee Cluster Library to run over Thread networks. By working together, ZigBee
and Thread can jointly provide an interoperable solution to help streamline product
development and ultimately improve the consumer’s experience in the connected home.
The ZigBee Cluster Library standardizes application level functionality for a wide variety
of devices used in smart homes and other markets. Thread is a wireless networking
protocol that can support multiple low-bandwidth, IP-based application protocols to
provide secure and reliable networks, simple connectivity and low power in the home.
Both organizations remain committed to their independence while cooperating to benefit
their respective members.
“Application level standardization is necessary to provide truly interoperable products to
consumers,” said Tobin Richardson, president and CEO of the ZigBee Alliance. “We
believe this agreement will deliver value to product
TM
External Use 51
developers searching for another solution for connectivity in the smart home.”
The ZigBee Alliance is a global association of companies working together to
enable reliable, cost-effective, low-power and wirelessly networked monitoring and
control products. ZigBee is a wireless standard used to connect a wide variety of
everyday devices to improve comfort, security and convenience in homes and
businesses.
“By agreeing to work together, ZigBee and Thread are taking a big step towards
reducing fragmentation in the industry,” said Chris Boross, president of the Thread
Group and technical product marketing manager, Nest. “Thread is designed to work
with and support many different application layer protocols, and we look forward to
working with ZigBee to create a combined solution for the connected home.”
Thread enables product developers to create, and consumers to enjoy, products
that easily and securely connect to a low-power wireless mesh network, with direct
Internet and cloud access for every device. Using proven standards including IPv6
technology with 6LoWPAN and standard 802.15.4 radios as its foundation, Thread
gives product developers a reliable low-power, self-healing, and secure network
over existing wireless standards.
