问题 I am rehistering succesfully a device in a Azure IoT hub via device provisioning service, but i want to disable the property Enable connection to IoT Hub to disable for every registered device. Is there any way to do this from the code. 回答1: You can use the REST API that allows to create or update enrollments (either group enrollments or single enrollments), in particular the provisioningStatus flag. (there is a similar API for individual enrollments). Next time your device tries to use DPS

问题 I'm using the Azure IoT Edge runtime running Linux containers on a Windows host OS. I have two modules, ModuleA and ModuleB. ModuleA have a registered direct method called "MethodA" and ModuleB have a registered direct method called "MethodB". When I invoke MethodA I want the method to invoke MethodB located in another module (but running in the same IoT Edge runtime). I'm using the Azure IoT SDK for c# and in the Init() function of ModuleA I have: await ioTHubModuleClient

问题 I am trying to use the preview version of the Azure IoT Hub API to create multiple devices (bulk) in a REST call. The API keeps returning "Request does not contain any devices" which is weird because I am formatting the request exactly as per the documentation. Here is the details of the call: Host https://<hub-name>.azure-devices.net/devices?api-version=2019-07-01-preview Headers Authorization: valid-sas-token-(tested this one), Content-Type: application/json Body { "devices":[ { "id":"TD

问题 I need to send a message from the IoT Hub to the DevKit Device.
