AzureIoTClient | 88:248736be106e | 5 | * @brief APIs that allow a user (usually a device) to communicate |
AzureIoTClient | 88:248736be106e | 6 | * with an Azure IoTHub. |
AzureIoTClient | 88:248736be106e | 7 | * |
AzureIoTClient | 88:248736be106e | 8 | * @details IoTHubDeviceClient_LL is a module that allows a user (usually a |
AzureIoTClient | 88:248736be106e | 9 | * device) to communicate with an Azure IoTHub. It can send events |
AzureIoTClient | 88:248736be106e | 10 | * and receive messages. At any given moment in time there can only |
AzureIoTClient | 88:248736be106e | 11 | * be at most 1 message callback function. |
AzureIoTClient | 88:248736be106e | 12 | * |
AzureIoTClient | 88:248736be106e | 13 | * This API surface contains a set of APIs that allows the user to |
AzureIoTClient | 88:248736be106e | 14 | * interact with the lower layer portion of the IoTHubClient. These APIs |
AzureIoTClient | 88:248736be106e | 15 | * contain @c _LL_ in their name, but retain the same functionality like the |
AzureIoTClient | 88:248736be106e | 16 | * @c IoTHubDeviceClient_... APIs, with one difference. If the @c _LL_ APIs are |
AzureIoTClient | 88:248736be106e | 17 | * used then the user is responsible for scheduling when the actual work done |
AzureIoTClient | 88:248736be106e | 18 | * by the IoTHubClient happens (when the data is sent/received on/from the wire). |
AzureIoTClient | 88:248736be106e | 19 | * This is useful for constrained devices where spinning a separate thread is |
AzureIoTClient | 88:248736be106e | 20 | * often not desired. |
