The CT301 radio facilitates a IEEE 802.15.4 based radio communication. It uses a proprietary wireless
communication stack to implement a star or cluster network with multiple nodes communicating simultaneously.
The radio module provides three basic functions:
• Transparent communication between network node and network coordinator
• Writing parameters to the radio module for configuration to determine its mode of operation such as the
configuration of a node or coordinator
• Reading parameters from the radio module
All communication to the radio module is established through a UART communication interface.
