title: How to check if any bluetooth device is connected in react native
body: <p>I've been attempting to detect whether a bluetooth device is connected to an android phone once a button is clicked. If detected, I would like to interact with this device from within my app. The device I'm talking about is <a href="http://www.senanetworks.com/sd1000-01.html" rel="nofollow noreferrer">http://www.senanetworks.com/sd1000-01.html</a> .</p>
  <p>I've used the example code of <a href="https://www.npmjs.com/package/react-native-ble-manager" rel="nofollow noreferrer">https://www.npmjs.com/package/react-native-ble-manager</a> to test it out, but unfortunately, it's not picking up this device even though the regular settings app does. Additionally, checking for already connected peripherals does not work if I connected to the device outside of the app. Any tips on how to do this?</p>
