Device Troubleshooting

Try any of these procedures in order to troubleshoot problems with your device or software.

I am trying to switch on my IDBLUE.HF device but the device is not responding.

Please ensure that the device is fully charged and that you are pressing the Power Button for at least 2 seconds.

I just noticed that my Device Status LED has switched from blinking green and blue (or magenta) to blinking yellow and blue (or magenta).

The Device Status LED light is informing you that the IDBLUE device is running low on power and may require charging shortly.

I just noticed that my Device Status LED has switched from blinking yellow and blue (or magenta) to blinking red and blue (or magenta).

The Device Status LED light is informing you that the IDBLUE device is now very low on power and will shut down shortly. Charge the IDBLUE device as soon as possible.

I plugged in my IDBLUE device for charging over a wall unit, but the Device Status LED does not indicate charging.

Ensure that the wall socket has power, trying another wall socket to be sure. If neither works, try connecting the device to a computer using a USB cable to charge the device from the computer.

I am able to search my IDBLUE device from the application, but cannot connect using Bluetooth.

Your PDA or computer may be looking to exchange passkeys. If you are not noticing a prompt asking you to enter a passkey, please access the Bluetooth module of your PDA or computer and add the device first before attempting a connection over an application.

An IDBLUE device is a Bluetooth slave and therefore, cannot connect to more than 1 other Bluetooth device. Please ensure that no other PDA or computer is connected to your IDBLUE device.

I am trying to search/connect to the IDBLUE device via Bluetooth but the operation continues to fail.

IDBLUE.HF comes with a Bluetooth Timeout setting that shuts down the Bluetooth link on the IDBLUE device if the device does not have an active Bluetooth connection. Press and release the Power button to re-enable the Bluetooth link on the IDBLUE device.

My IDBLUE device disconnects from my application without any warning.

The IDBLUE device can disconnect from the application under any of these circumstances:

  • The IDBLUE device is not within range of the PDA or computer hosting the application. Move the IDBLUE device within Bluetooth range to re-establish the connection.
  • The Device Idle Timeout expires if the specified period of time elapses without the user pressing a button on the IDBLUE device or the application communicating with the IDBLUE device. The IDBLUE device must be turned back on such that the connection can be re-established.
  • The IDBLUE device runs out of battery power. Charge the IDBLUE device to re-establish the connection.

I have established connection to the device and having successful reads. However, the information of my reads is not being communicated back to my host application.

The IDBLUE device sends the information back to the host application asynchronously via the established Bluetooth connection. Ensure that the connection is active and that the application is properly processing the asynchronous information from the IDBLUE device. Refer to the IDBLUE.HF Firmware Interface Guide for more information.

The IDBLUE device must be configured in a Connected Mode to retrieve the asynchronous tag information. Refer to the section Connected Operating Mode for more information.

If my IDBLUE device has an onboard memory, why is it that my tag scans are not getting saved?

IDBLUE.HF’s onboard memory only saves information in Tag Store Disconnected Mode, not in Tag Verify Disconnected Mode or when it is connected to an application. Refer to the section Operating Modes for more information.

I am trying to read a tag but keep seeing a red light in the read LED indicating an unsuccessful scan.

IDBLUE.HF may not be able to successfully read a tag in any of the following circumstances:

  • IDBLUE.HF is a near field reader and while its specs may indicate a read range of up to 3 centimeters, this is also dependant on the size of the tag. Smaller tags, or tags with weak antennas will require a closer read range. Ensure the IDBLUE device is within close proximity of the tag.
  • Tags that have experienced wear and tear, or have been damaged may work but will do so erratically.
  • The tag you are scanning supports a protocol which the IDBLUE device does not support. Refer to section RFID Protocols for more information on the protocols supported by IDBLUE.HF.

I am trying to read/write the user memory of the tag. I am in proximity to the tag but the Reading Status LED remains blue.

A read/write operation to/from a tag’s user memory is a longer operation than a simple tag ID read/write and depending on the amount of information stored on the tag, can take much longer to read/write. Please ensure that you keep the IDBLUE device in the specified range until the Reading Status LED indicates a successful (green) or unsuccessful (red) read/write.

 

If any of these questions doesn’t seem to apply, please try to contact support and we can walk you through any issues you might be encountering.
