What is the process for obtaining an AWS IoT device shadow on an Android app? I have been utilizing a REST API generated by AWS, however, I am unsure of how to include headers with this API

I have successfully implemented a web server in Node.js where a continuous script is running and the shadow will be updated based on user input.

This link provides information on adding canonical headers. Should I include any additional headers if I am mistaken with this?

This link discusses web socket communication related to my query.

Based on the above links, I learned how to accomplish this on an Android mobile device but received the same response.

In my case, I utilized NodeJs for Raspberry Pi communication, which functioned properly and updated it successfully.

How can I retrieve the same shadow from the application?

Answer №1

Learn how to utilize ThingShadow in your mobile application with an example from GitHub. https://github.com/awslabs/aws-sdk-android-samples/blob/master/TemperatureControl/README.md

AWS offers convenient tools for accessing ThingShadow.

import com.amazonaws.services.iotdata.AWSIotDataClient;
import com.amazonaws.services.iotdata.model.GetThingShadowRequest;
import com.amazonaws.services.iotdata.model.GetThingShadowResult;
import com.amazonaws.services.iotdata.model.UpdateThingShadowRequest;
import com.amazonaws.services.iotdata.model.UpdateThingShadowResult;

Answer №2

When working with AWS IoT Shadow, there are a few ways you can interact with it:
1. Utilizing HTTP with IAM credentials
2. Using HTTP with X.509 certificate based authentication
3. Connecting via MQTT endpoint

AWS offers SDKs for both HTTP and MQTT to help you easily manage shadow operations. For more information on RESTful APIs, you can refer to the official AWS IoT Documentation.

Keep in mind that accessing data via HTTP requires proper authentication, including performing the SigV4 signing process with IAM credentials, which is automatically handled by AWS SDKs. If you need to do this manually, remember to include the necessary signature in your request.

For additional support from AWS, consider posting a question or concern on the AWS Forums. The community and developers can provide valuable assistance and guidance.
