# Device Kit

> Connect supported BLE and USB hardware to repeatable field workflows.

Device Kit is the hardware integration layer used by Dsync. It discovers visible devices, matches them to a device profile, opens the appropriate connection, and exposes the operations, settings, and workflows that the profile supports.

## The integration path

<Steps>
  <Step title="Discover">
    Device Kit scans the visible BLE advertisements and USB devices available to the app.
  </Step>

  <Step title="Match">
    It compares the candidate's identity information with the profile's matching rules.
  </Step>

  <Step title="Connect">
    It opens the matching BLE or USB transport and starts a device session.
  </Step>

  <Step title="Operate">
    Dsync can invoke the profile's named operations, read responses, update settings, or run rules and workflows.
  </Step>
</Steps>

<Note>
  Device Kit only knows what the active device profile describes. A device can be powered on and visible but still produce no candidate when its identity rules do not match.
