Can a progressive web app (PWA) run a background service on a mobile device to get data from hardware (accelerometer, gps...)? : <p>I see we can check the capabilities of a mobile browser using <a href="https://whatwebcando.today/" rel="noreferrer">https://whatwebcando.today/</a>, but can the hardware APIs be queried when not running on foreground?</p>

<p>I mean... With PWA am I able to build an app that gets hardware info while running in background, just like Octo U, for Android, and posts that info to a web server?</p>
