BatchAssociateClientDeviceWithCoreDevice
Associates a list of client devices with a core device. Use this API operation to specify which client devices can discover a core device through cloud discovery. With cloud discovery, client devices connect to Amazon IoT Greengrass to retrieve associated core devices' connectivity information and certificates. For more information, see Configure cloud discovery in the Amazon IoT Greengrass V2 Developer Guide.
Note
Client devices are local IoT devices that connect to and communicate with an Amazon IoT Greengrass core device over MQTT. You can connect client devices to a core device to sync MQTT messages and data to Amazon IoT Core and interact with client devices in Greengrass components. For more information, see Interact with local IoT devices in the Amazon IoT Greengrass V2 Developer Guide.
