Bluetooth RFID Reader pages in the hardware section updated.

The Bluetooth RFID Reader pages in the hardware section has been updated now. I finally added pictures of the RFID Reader in a plastic enclosure printed by to the post. I’m currently preparing a short demo video showing the RFID reader connected to the iPhone in action.

    Hi Micheal,

    I am interested in the RFID reader. Do you have the video posted somewhere?

    Thank you,

    I am very interested in the RFID reader. One question, how did you get it to show and hide the iOS keyboard? Does it disconnect the bluetooth?

      Hi Phil,
      no I’m not disconnecting Bluetooth. I’m sending a special media key similar to the CD eject button on the Apple Bluetooth keyboard.

    Dr. Kroll,
    I am currently sourcing RFID readers (iOS compatible) for use in a new pick, pack and ship eCommerce warehouse. How much are you selling your units for? We would need 10-20 to start in the next 4-6 months. Sorry, I could not find a contact email for you.

      Hello Joe,
      the reader was just a feasibility study in order to see if I can create the board and a fitting enclosure which is 3D printed. Sorry but I’m currently not selling them and there are no plans in the future to do this. I would like to change the design an use a Bluetooth Low Energy module to connect the RFID reader to the iPhone.

    To connect Iphone, Ipad you use HID Profile, should be used
    Apple authentication co-processor for WT12?

    • Michael Kroll November 8, 2012 at 13:18 #

      No there is no need for a co processor. HID works without it.

    Thank you for your previous answer.

    Tell me more please, where on the site I can find information about Human Interface Device Profile (HID)

    Because the information that I have found, refer to the Bluetooth 4.0 Low Energy (LE).

    Maybe I need to join to find out more about HID Bluetooth Profile?

      Maybe this link will help you?

        Thank you =)
        I am now reading this document, I thought maybe there is any specificity that in the work iOS with HID Bluetooth Profile.

          And one more question:
          – Data from the keyboard (Input Reports) sent to the iOS device, but iOS supports the option to send the data back (Output Reports)?

          • Michael Kroll November 12, 2012 at 10:56 #

            I think you can only send data to iOS. Sending from iOS is not possible as I know.

    It was expected from Apple.
    Thank you for your answers and attention once again
