Accessing Heart Rate Monitor (HRM) Sensor data for Native applications

What is Heart Rate Monitor Sensor?

The Heart Rate Monitor (HRM) sensor measures a person's heart rate in real time.

Tizen provides interfaces and methods to manage sensor data from various sensors on the device. The main purpose of a sensor is to provide a value for the relevant parameter. In native application development, accessing the gear’s Heart Rate Monitor (HRM) sensor data is quite straight forward. The main obstacles with reading from the HRM are getting the right permissions and utilization of Sensor API.

Tizen NFC Card Emulation Mode


Near field communication (NFC) is a form of contactless communication between devices or between a device and a chip/tag. Using NFC, a user can transfer/receive small amount information from a short distance (example, 10 cm).

Card-emulation mode, as the name suggests, makes the device behave like a contactless smart card. Using this mode we can develop virtual credit cards, debit cards, transit cards, and access cards. In this tip document, sample code from a Web app is shown for understanding.



WebView in Native Application


When developing Tizen Native application, a need for launching web browser can be satisfied by WebView API. In this tip document, simple steps are shown on how to create a simple web browser in a Native application. The WebView API implements the EFL WebKit (EWK), which covers various features for Web browsing, such as loading and displaying Web pages and navigating through the browsing history.

Charts for Tizen Web app


Charts are a great way to view data. Using charts, not only we can summarize huge data but also get a more pleasant view of it. App that is based on data collection and processing can be made more interactive and visually attractive by using charts.


Chart.js is an open source (MIT) JavaScript library for displaying beautiful charts in HTML5 applications. The charts are rendered on HTML5 canvas element. It is supported in web, mobile and tablet. It offers most common type of charts like line, bar, pie etc.

Creating a native service for Tizen wearables - part 2: service launcher

This article is the second part of the “Create a native service for Tizen wearables” series. In this part we will show how to create a service launcher application and distribute it as the Combined Package with an already created service as well as how to communicate between the launcher application and the service aplication.
