We developed a product against the Zigbee Home Automation specification using RapidHA. How do we update to Zigbee 3.0?
If you have developed an end device, you can update to the latest Zigbee 3.0 compliant RapidConnect firmware via the built-in Serial Upgrade or OTA (over-the-air) Upgrade features.
If your device is a router or coordinator, you will need to migrate to the latest RapidConnect Module to gain access to a Zigbee SoC that supports the Zigbee Green Power Proxy functionality.
In both cases, the vast majority of the serial commands will be identical to your previous implementation. However, you will need to add support for a few new Network Commissioning serial commands from the RapidConnect Serial Protocol.
