Troubleshooting Bluetooth connection loss (scanner, printer, card reader)

This article goes through some tips for troubleshooting if you are encountering issues with losing the connection between your iPad and your scanner, printer or card reader.

  1. Is your iPad going into sleep mode?
    Try to increase the time your iPad takes to auto-lock at Settings > Display and Brightness > Auto-lock.
  2. Are the devices too far away from one another?
    Make sure all the devices (iPad and scanner, printer or card reader) are in close proximity to one another.
  3. Is something interfering with your signal?
    • Avoid using your wireless devices near common sources of interference like power cables, microwave ovens, wireless video cameras and cordless phones.
    • Reduce the number of active devices that use the same wireless frequency band.
    • Configure your Wi-Fi router to use a different Wi-Fi channel or have it scan for the channel with the least interference.
  4. If you’re using USB 3 devices with your computer, try the following:
    • Use a high-quality, shielded USB cable with each USB 3 device.
    • Move your USB 3 devices — including any USB hubs — further away from your wireless devices.
    • Turn off any USB 3 devices that aren’t in use.
    • Avoid physical obstructions in the path of your wireless signal.
  5. Do you have any unneeded Bluetooth connections?
    Remove old Bluetooth connections.
  6. Is your firmware up to date?
    Update the hardware’s firmware.
