与Auzure IoT中心的设备连接性（联机/脱机）状态 [英] Device connectivity(online/offline)status with the Auzure iot hub

问题描述

我已将移动设备连接到IOT集线器。我想在另一台设备上安装的IOT集线器服务应用程序上显示该设备的连接（联机/脱机）状态。如何实现呢？连接状态发生变化时，是否会触发任何自动触发/事件？服务SDK中也有任何API可以检查设备的连接状态。

I connected my mobile device to the IOT hub. I would like to display the connectivity (online/offline) status of the device on IOT hub service app installed on another device. How to achieve this? Is there any automatic trigger/event that fires when there is change in connectivity status? Also is there any API in service SDK to check the connectivity status of the device.

推荐答案

是的，我们在以下位置发布设备连接状态事件网格，可用于触发： https://docs.microsoft.com/zh-cn/azure/iot-hub/iot-hub-how-to-order-connection-state-events

Yes, we publish device connection state on Event Grid, which can be used for trigger: https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-how-to-order-connection-state-events
