I have some issues concerning a project of mine. Specifically, the project consists of creating an app in Tizen that records Heart Rate (HR) data and sends them from a Samsung Galaxy Watch (where the app is installed) to a server that I have created with nodejs.
I have problems with the main.js file of the app: in order to send data to the server I have mentioned above, I use XmlHttpRequest() to create a POST request. Unfortunately, data are not sent to the server even though no errors come out while installing the app from Tizen in the smartwatch.
Has anyone developed a similar project? Does anyone know how to create the connection between server and smartwatch to send HR data?

Thanks in advance for your suggestions.

Vittoria.

  • Hello, would you let us know your project type: Native / Web / .NET apps? I think... sending data to server directly is a difficult approach than using Mobile device (companion device). could you consider this approach?

  • It's a web app installed on a watch? If it is an app installed on a Samsung device try runing `adb logcat` to catch any errors that occur and add some logging info so you see it in logcat. – Robel Robel Lingstuyl Nov 17 '21 at 04:36
  • Please provide enough code so others can better understand or reproduce the problem. – Community Nov 17 '21 at 04:37
