Yes! Our latest RapidConnect firmware enables the development of Zigbee 3.0 compliant products when operating on our latest RapidConnect Module.
For our previous generation (EM357-based) RapidConnect module, it is not currently possible to support the Zigbee Green Power (ZGP) Proxy functionality due to a limitation in the ZNET stack from Silicon Labs. In Zigbee 3.0, ZGP Proxy became a mandatory feature for all routers and coordinators. Therefore, end devices are the only device types that can be built using an EM357 SoC and still be Zigbee 3.0 certifiable.
