I am self-nominating my apis-saltans project, providing a Zigbee implementation including a coordinator API.
The most notable crates of the workspace are:
apis-saltans-corewith the core Zigbee data types and traits.apis-saltans-zclwith an implementation of the Zigbee Cluster Library.apis-saltans-zdpwith a Zigbee Device Profile implementation.apis-saltans-hwA generic API for implementing hardware drivers.apis-saltans-coordinatorA Zigbee coordinator API.
The hardware API is currently implemented for EZSP and tested successfully on a Siliconlabs MGM210P22A.
