Zigbee
Mature, reliable, and flexible, Zigbee's full-stack platform was designed for mesh applications and built for the IoT from the ground up. With a rich cluster library and a powerful open standard (Dotdot), Zigbee lets device-makers build products that speak the same language, creating highly interoperable ecosystems across multiple verticals.
TLSR921x Series
The TLSR921x series is a low - power, high - performance, multi - protocol wireless connectivity SoC. It has the remarkable ability to support Bluetooth Low Power, Bluetooth Mesh, Zigbee, Thread, Matter, Apple HomeKit, Apple Find My network, and 2.4 GHz proprietary protocols all on a single chip. The TLSR921x incorporates a potent 32 - bit RISC - V MCU and security features, which renders it highly suitable for a broad range of high - end iot devices.
