title: Is there a way to send sensor data from a Samsung Gear S3 watch(e.g. heart rate data) to a smartwatch app(react native or Ionic app) via bluetooth?
body: <p>I am trying to find a way to send a bunch of sensor data from a Tizen smartwatch app to a smartphone using Bluetooth.
  I have built the Tizen app for a Samsung Gear S3 werable using the web API but I'm stuck on how to communicate with mobile devices. </p>
  
  <p>Currently I'm savng all the sensor data in an Indexed DB and I would like to sync with an app on the user's phone where I can access the data and process it.</p>
  
  <p>I have looked into the Samsung Accessory Protocol (SAP) API but it seems to only support android phones and I want a solution that works on iOs devices too.
  See here for more details:

  <p>Is there a way to send data via bluetooth from the Samsung Gear S3 to an iphone and an android phone and if yes what can I use to achieve this? I am looking into using react native or Ionic to build my smartphone app, but I cannot figure out how to establish a way to receive bluetooth data from the Gear S3.</p>
  
  <p>Any help or resource that can point me in the right direction is greatly appreciated.</p>
