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 AWS IoT Greengrass to retrieve associated core devices' connectivity information and certificates. For more information, see Connect client devices to core devices in the AWS IoT Greengrass V2 Developer Guide.

Note

Client devices are local IoT devices that connect to and communicate with an AWS IoT Greengrass core device over MQTT. You can connect client devices to a core device to sync MQTT messages and data to AWS IoT Core and interact with client devices in Greengrass components. For more information, see Interact with local IoT devices in the AWS IoT Greengrass V2 Developer Guide.
