Using Device Central

Device Central 3.3

Overview

This section describes how to use Device Central. Device Central supports pairing/unpairing of all Bluetooth peripherals that follow the Bluetooth standards.

Exception: Unpairing a Bluetooth Scanner peripheral is currently not supported. Zebra Bluetooth scanners act as a master device which controls the pairing and connection with mobile computers. These Bluetooth scanners have the re-connect feature which may be initiated on the scanner itself. Therefore, unpairing the Bluetooth scanner from a mobile computer will not remove the paired information completely. To address this, pressing the re-connect button on the Bluetooth scanner will re-establish the pairing and connection with mobile computers.


Pair/Unpair a Peripheral

This section describes how to pair to a peripheral, view the paired devices list, and unpair a peripheral.

Pair to a Peripheral

Pairing to a Bluetooth peripheral is accomplished by one of the following 3 methods:

  • Scan and Pair: Mobile computer scans the Bluetooth MAC address barcode label on the peripheral
  • Scan to Pair: Peripheral scans the pairing barcode displayed on the mobile computer
  • Manually Pair: Manual entry of the peripheral Bluetooth MAC address.

The subsequent sections cover each method to pair the mobile computer to a peripheral.

Scan and Pair

Upon launching Device Central, a DataWedge profile named "DeviceCentral" is created for scanning support. This profile is not intended to be modified - the profile settings are reset to the defaults upon each application launch. The 2 methods to scan the peripheral’s Bluetooth barcode to pair are:

  1. Hardware trigger - Press the hardware scan trigger when the main screen is displayed.
  2. Soft trigger - Press the "Scan barcode to pair" button from the main screen. See Using Soft Trigger section below.

If any of the following conditions occur in the middle of operation, the hardware and software trigger will not be responsive in Device Central:

  • DataWedge is disabled
  • "DeviceCentral" DataWedge profile is disabled
  • "DeviceCentral" DataWedge profile is deleted

Using Soft Trigger:

  1. Launch Device Central from the Apps menu.

  2. In the Scan and Pair tab, tap Scan barcode to pair button.

  3. The scan beam is illuminated. Scan the Bluetooth MAC address barcode label on the desired peripheral to pair. Ensure that Bluetooth is enabled on the peripheral and is set to discoverable mode. Refer to the peripheral user guide for instructions.

  4. When pairing is successful, the peripheral is displayed in the list indicating that it is paired. A green dot next to the listed device indicates that the device is connected and may be in use. Other peripherals such as a Bluetooth headset or printer device will have a red dot until the respective application is using these Bluetooth peripherals.


Scan to Pair (Display Barcode to Pair)

To pair by scanning the displayed barcode on the mobile computer. This applies to peripherals that have scanning capability, such as Bluetooth handheld scanners (ie. DS3678) and ring scanners (ie. RS6000):

  1. Launch Device Central from the Apps menu.

  2. In the Scan and Pair tab, tap Display barcode to pair button.

  3. A barcode is displayed.

  4. Using the peripheral, scan the displayed barcode.

  5. When the pairing is successful, the peripheral is displayed in the list with a green dot indicating that it is paired.


Manually Pair

To pair a peripheral manually if unable to pair via Bluetooth:

  1. Launch Device Central from the Apps menu.

  2. In the Scan and Pair tab, tap the MAC address field.

  3. Enter in the Bluetooth Mac address for the peripheral to pair to.

  4. When pairing is successful, the peripheral is displayed in the list. A green dot next to a Bluetooth scanner indicates that the device is connected and may be in use. Other peripherals such as a Bluetooth headset or printer will have a red dot until the respective application is using these Bluetooth peripherals.


Paired Device List

Once pairing is complete, the peripheral is listed in the Scan and Pair tab. The paired peripherals are listed by device name, showing the connected state as indicated by the green (connected) or red (disconnected) dot. An Unpair button next to each peripheral allows the capability to unpair each device individually. For identified devices, the icons for each peripheral represent the type of device by category, such as scanner, headset and printer. All other unidentified are displayed as generic Bluetooth icons.

Unpair a Peripheral

To unpair a Bluetooth peripheral:

  1. Launch Device Central from the Apps menu.

  2. In the Scan and Pair tab, tap the Unpair button for the desired peripheral to unpair.

  3. A confirmation pop-up message appears. Tap OK.

  4. Once unpaired, a message appears indicating the peripheral has been disconnected and the peripheral is removed from the list.

    • Volume - set the volume level percentage % (1-100) for the audio feedback sound
    • Haptic Feedback:
    • Duration - set the time in milliseconds (500-1,800,000) equivalent to 0.5 seconds to 30 minutes for the haptic, or vibration, feedback to take place

  4. When the connected Bluetooth peripheral moves out of range and becomes disconnected from the device, by default a notification message appears in the notification drawer:


Configuration

Some features may be controlled through StageNow, an Enterprise Mobility Management (EMM) system (sometimes referred to as Mobile Device Management, or MDM), or a custom application using Zebra's Device Central Manager CSP. The Device Central application must be installed on the device before configuring with Device Central Manager CSP. The features that can be controlled include:

  • Enable/Disable Single Pairing of the Same Device Class: If enabled, it allows only one device to be paired from each device category, such as scanner, headset and printer. This feature is deprecated from Device Central Manager CSP - starting with MX version 10.1, Zebra recommends to use Bluetooth Manager CSP to configure the same functionality.
    • For Bluetooth headsets, mobile payment modules and printers: If a device is already previously paired and another device of that same category type is being paired, the previously paired device will be automatically unpaired to allow the new device to be paired.
    • For Bluetooth scanners: If a device is already previously paired and another device of that same category type is being paired, the previously paired device will not be unpaired automatcially and the new device will not be paired until the previous device is disconnected or unpaired.
  • Enable/Disable Firmware Update Option: If enabled, it permits the ability to hide the Firmware Update button to prevent firmware updates from taking place.
  • Enable/Disable Bluetooth On/Off Option: If enabled, it prevents the user from accessing the option to turn the Bluetooth radio on or off. This option is accessible from the Settings screen (in the main screen tap on the top right hamburger menu and select Settings):
  • Smart Leash Option: Enable/disable Smart Leash and configure the Audio/Haptic feedback via Device Central Manager CSP.
  • Enable/Disable Silent Pairing Option: If enabled and configured, it allows the confirmation prompt to be bypassed during the pairing process. Use Bluetooth Manager CSP to configure this option.
