Real-time Communication and Analysis Tutorial
Overview​
This tutorial demonstrates an example application with two concurrent components: a publisher and a subscriber.
- Publisher: Simulates a patient application where a device measures the blood glucose level and creates a new reading using Cardinal.
- Subscriber: Receives the created medical data in real time and modifies it with the analysis results.
This example is useful for scenarios where a backend service (e.g., an AI algorithm) needs to continuously analyze data as soon as it's created.
You will not find the Subscriber Dart examples, as it is designed to represent a back-end application use case. You can still test your Publisher in Dart by launching the Subscriber in any other language.
Prerequisites​
Before starting, ensure you have:
- Completed the onboarding procedure to register for Cardinal.
- Created a database and added a healthcare party user.
- Familiarized yourself with the Cardinal SDK by following the introductory tutorial.
Be sure to generate an authentication token (i.e. a temporary password) for your healthcare party to be able to instantiate the SDK in the code examples.
The full code examples in Kotlin, Python, and TypeScript are available in this repo, where you will find a folder for each language.
The Dart code is available in this repo along with the instructions to run it on the Android and iOS simulator.
