External Hardware


Apps on mobile devices today can make use of a variety of external devices such as watches, cameras, other mobile devices and more. There are different tools that help link the app on the device with external hardware based on how such control is transmitted (e.g. Bluetooth, WiFi, USB Host, etc.) and what external hardware is being used.


Some popular communications links:


  • NFC, or near field communication, links devices when they touch or are in close proximity (radio waves are used).
  • Bluetooth is another type of wireless technology that can transfer information over short distances (but farther than NFC).
  • USB Host allows the app the link to an external device via USB connection.
  • Wi-Fi allows high speed networking.


Some external hardware mobile apps can now link to:


  • Arduino devices are built from microcontroller based kits made by Arduino. These devices can act as sensors or control interfaces with other devices linked to the mobile app.
  • Action cameras differ from conventional cameras because they are made to be attached to helmets, cars, bikes and other surfaces that move.
  • Drones are mobile external devices that move on their own power such as UAVs (unmanned aerial vehicles).
  • With the boom in mobile computing, more and better external hardware is expected to emerge in the near future for the Android app developer to leverage.

Onix knows how to apply external devices within the scope of Android ecosystem and offers solutions which help automate access or unfold the infrastructure of the augmented reality. Fast prototyping via Arduino allows us to implement any type of system in smart home technologies or robotics.
