Connect a Bluetooth scanner

Barcode scanners or QR scanners that provide a Bluetooth Classic keyboard emulation mode can be connected to a VTAP100‑PRO‑BW reader.

Note: This option is only available on VTAP100‑PRO‑BW readers

  1. If your VTAP100‑PRO‑BW reader is in Cloud mode, its configuration will be set up and sent through VTAP Cloud. Contact vtap‑support@dotorigin.com for help or more information.

    If your VTAP100‑PRO‑BW reader is in Local mode make the following changes in the config.txt file on your Local mode VTAP PRO reader to enable the Bluetooth scanner feature:

    • Set BTScannerMode=1 (because it is disabled by default, if not defined in config.txt).

      When this is enabled and the VTAP PRO reader is not currently paired with a scanner, it will begin scanning to find the first barcode/QR scanner it can pair with, then will stop scanning for new devices. When the setting is disabled any paired devices are removed and forgotten.

    • Set BTScannerOutput to define the output interfaces that the Bluetooth scanner data can be passed on to. Set c for output over ComPort, s for serial RS-232 and k for USB keyboard emulation. Multiple selections can be separated with commas such as BTScannerOutput=c,s,k

    • Check whether the ...Source setting for each output interface is set to any value other than =A5 (default). If it is, add 0x04 to the existing source bit value, to permit scanner data to be sent over an interface. (If a ...Source setting is not present in the config.txt file, the default value will allow scanner data through).

  2. Switch on your scanner to a pairing/discovery mode.

    The following are specific details for Pairing and connecting with NETUM C750 barcode/QR scanner.

    1. Switch on the NETUM scanner and press the top button once, enabling the pairing. The scanner will beep when button is pressed.

    2. The VTAP100‑PRO‑BW will automatically detect and pair with the NETUM scanner. Once paired, the scanner will beep again and show stable blue LED (indicating an active connection).

    3. Now you can start using the NETUM scanner and barcodes/QR codes scanned by the NETUM scanner will be sent to the VTAP reader in the same way as an NFC wallet card payload.

    To verify a successful pairing, power cycle the VTAP100-PRO-BW reader and check the VCBOOT.txt file in a text editor on the VTAP PRO file system. (Alternatively, send a ?vcb command to the VTAP100-PRO-BW reader over a serial interface and check the VTAP reader's response.)

    VCBOOT.TXT or the ?vcb response will contain a line with the syntax:
    Paired: <number of paired devices>,<names of the paired devices>.
    For instance Paired: 1,C barcode scanner.

The VTAP reader interface you choose to output the scanner data may require some extra configuration, described in the following examples. Your options are:
