 Extension GA

az iot device send-d2c-message

Send an mqtt device-to-cloud message.

The command supports sending messages with custom payload in unicode string or binary format. When intending to send binary, the data should come from a file (via --data-file-path) and content type should be set to application/octet-stream.

Note: The command only works for symmetric key auth (SAS) based devices. To enable querying on a message body in message routing, the contentType system property must be application/JSON and the contentEncoding system property must be one of the UTF encoding values supported by that system property(UTF-8, UTF-16 or UTF-32). If the content encoding isn't set when Azure Storage is used as routing endpoint, then IoT Hub writes the messages in base 64 encoded format. If using x509 authentication methods, the certificate and key files (and passphrase if needed) must be provided.

az iot device simulate

Experimental

This command is experimental and under development. Reference and support levels: https://aka.ms/CLI_refstatus

Simulate a device in an Azure IoT Hub.

While the device simulation is running, the device will automatically receive and acknowledge cloud-to-device (c2d) messages. For mqtt simulation, all c2d messages will be acknowledged with completion. For http simulation c2d acknowledgement is based on user selection which can be complete, reject or abandon. The mqtt simulation also supports direct method invocation which can be acknowledged by a response status code and response payload. Note: The command by default will set content-type to application/json and content-encoding to utf-8. This can be overriden. Note: If using x509 authentication methods, the certificate and key files (and passphrase if needed) must be provided.
