Beacon-based handover option for commissioning and control of wireless network devices
The present invention relates to methods and apparatuses for controlling commissioning and/or control of a combo network device with dual connectivity in a wireless network by using a smart device. In a factory new state, the combo network device has not yet joined any wireless network by its first connectivity (e.g. Zigbee) and thus broadcasts a beacon with beacon information to solicit a connection from the smart device by its second connectivity (e.g. BLE). If the combo network device joins a wireless network, it enters an associated state in which the beacon information will now contain an identification of the wireless network. Thus, the beacon information changes based on the status of the combo network device and supports a handover process for an installer or controller.
