Bluetooth Questions

How far can my IDBLUE device be from a PC/Pocket PC/mobile device before it loses connection?

Bluetooth has a theoretical range of 15m (48 feet) but in every day scenarios, ideal range is 15 to 20 feet.


How do I pair your device over Bluetooth?

To pair our devices via Bluetooth:

  • Step 1: Turn on your IDBLUE device.
  • Step 2: Go into your System Bluetooth Settings.
    • Windows: Find the Bluetooth icon located in the system tray in the bottom right side of your desktop. Click on the Bluetooth icon and select “Add a Device” from the context menu.
    • Android/iOS: Under System Settings > Bluetooth, ensure Bluetooth is turned on and tap “Search for Devices” if it doesn’t automatically search.
  • Step 4: Place the IDBLUE device in Discovery Mode by pressing and releasing the power (rear) button. The rear LED should flash blue to indicate discovery mode for 2 minutes.
  • Step 5: The device should show up in the Bluetooth menu.
    • Windows: In the Add a Device window, the new device should show up. Highlight the device ID and click Next.
    • Android/iOS: The new device should show up in the Bluetooth menu. Tap the device name to start pairing.
    • Note: The IDBLUE device ID can be found on the back label, and should be of the format IDBLUE-(U)HF-XXXX.
  • Step 6: Enter the pairing code for the device. The default pairing code is ‘0000’ (Four zeros) – enter this pin code and click Next.
    • Note: For iOS, no pairing code is required.

That’s it! You device should now be properly Bluetooth paired – You are done.

  • If you have a Bluetooth SPP version of our RFID devices, it should load the necessary Bluetooth SPP drivers and when completed, it should be detected in any application using our IDBLUE SDK.
  • If you have a Bluetooth HID version of our RFID devices, it should load the necessary Bluetooth HID drivers and when completed, will enter the tag information in any location you can enter keyboard input.

For detailed information, please refer to our Bluetooth Pairing Guide or the IDBLUE User’s Guide on the IDBLUE Documentation page.


Are there any recommended Bluetooth dongles?

IDBLUE devices will work with any Bluetooth dongle that supports the Serial Port Profile (SPP). However, the out-of-the-box applications require a dongle that support one of Toshiba, Broadcomm or Microsoft Bluetooth stacks. Dongles that are known to work with IDBLUE devices are:

  • D-Link DBT-122 (Recommended)
  • D-Link DBT-120
  • IOGear GBU201
  • IOGear GBU301
  • IOGear GBU211
  • IOGear GBU311


What is Bluetooth SPP and HID? Which device version do I need?

When connected via Bluetooth, our devices are configured to use one of the following Bluetooth predefined profiles:

  • Serial Port Profile (SPP) – The IDBLUE device is configured using the Bluetooth serial port driver that can send and receive commands using our IDBLUE API. This allows:
    • total UI control and access to all features
    • integration with any 3rd party application
    • ability to read the Tag ID or read/write to the tag’s user memory
    • requires our IDBLUE API to communicate with our device.
  • Human Interface Device Profile (HID) – The IDBLUE device is configured using the Bluetooth HID driver as an input device that can only send specific tag information of the first successful tag scanned as text output when the Action Button is pressed. Because the device is not configurable over Bluetooth and operates similar to a keyboard wedge, it doesn’t need extra development time for integration and works “out of the box” using existing Bluetooth drivers for many host OS’s (including Google Android, Apple iOS,  RIM Blackberry, MS Windows, etc…).  When scanning tags, the device will output:
    • HF tags – the Tag ID.
    • UHF tags – the EPC code from the EPC memory bank.

Available Communication Methods


If you need to just scan the Tag ID/EPC  code into an application, we recommend our IDBLUE HID Bluetooth versions of the IDBLUE.HF and IDBLUE.UHF reader without any additional software needed. If you need to integrate more functionality over Bluetooth, we recommend our IDBLUE SPP Bluetooth versions of our IDBLUE.HF or IDBLUE.UHF readers which will require our API via our IDBLUE SDK to control the device.

NOTE: If you want to use our SPP Bluetooth version as a keyboard wedge:

  • Microsoft Windows –  you can download our IDBLUE Keyboard Sender for Windows available on our Device Drivers and Software page.
  • Google Android – you can download our IDBLUE Keyboard Wedge for Google Android on our Device Drivers and Software page.
  • Apple iOS – Due to OS limitations and restrictions, a keyboard wedge for iOS is not available.


Both types of our devices operate the same when connected over USB via Windows using our IDBLUE USB driver for Windows and have access to the full feature set of our readers.
