JenNet Protocol Stack
JenNet is a network protocol stack designed to work with our family of wireless microcontrollers and modules. JenNet allows wireless sensor networks to be easily built, from simple point-to-point cable replacement to complex tree networks.
JenNet supports star, tree and linear network topologies, and provides self-healing functionality for robust communication. Developed on the IEEE802.15.4 standard, which operates in the globally unlicensed 2.4GHz band, JenNet co-exists with Wi-Fi and Bluetooth.
Interaction with JenNet is achieved via an easy-to-use 'C' programming interface.
This interface provides simplified access to all network functions, reducing the need for designers to understand the complexities of wireless networks.
