I am building a coordinator using RapidConnect. What happens if my device is power cycled after it has formed a Zigbee network and other devices have been commissioned?

When a RapidConnect-based coordinator is power cycled, it will try to automatically reform the network with the same security keys. The Host doesn't need to do anything to prompt this action or to allow the other devices to rejoin the network.

However, this automatic reforming of the network will not happen until the Host executes startup configuration. In other words, your Host must have code to configure the endpoints and device type of the RapidConnect module each time it is power cycled.
