Bluetooth® Bumpbar (TDS-BLE) Documentation

Specifications:

Bluetooth^® Version: Bluetooth^® Low Energy 5.4
Host Device Requirements: Windows 10/11, Android 10 or Newer*^, MacOS*, Linux*^
Range: ~50' with line of sight to host device, less in crowded environment
Expected Battery Life: >1 Year with included 2x AA alkaline batteries, longer if Lock Sounds and Button Chirp are turned off; LED only active during pairing/un-pairing process
KDS Compatibility: Any KDS System which uses Modes 1, 2, 3, 6, or 7 on traditional USB KRS Bumpbar (custom Mode 4 allows for much greater compatibility)

Connected (Green, Slow Flash): Bumpbar is connected to host device (LED turns off after 90 seconds to conserve battery).
Low-Power Hibernation Mode (Red, Slow Flash): Bumpbar is disconnected from any host device and is in low-power hibernation mode (LED turns off after 90 seconds to conserve battery). If previously connected to a host device, press any button to wake, otherwise press and hold any corner button to enter Pairing Mode.
HID Pairing Mode (Blue, Fast Flash): Bumpbar is in HID pairing mode and is discoverable in host device's Bluetooth menu. Bumpbar re-enters low-power hibernation after 90 seconds.
KRS Custom Pairing Mode (Violet, Fast Flash): Bumpbar is in KRS Custom pairing mode and is discoverable in host device's Bluetooth menu. Bumpbar re-enters low-power hibernation after 90 seconds.

If pairing a new Bumpbar, press and hold any corner button of Bumpbar for 3 seconds to enter pairing mode. If Bumpbar was previously paired to a different host device, unpairing is recommended (see How to Unpair Bluetooth^® Bumpbar).
Within 90 seconds, select your Bumpbar in desired host device's Bluetooth menu (Device Name begins with "KRS-" followed by a unique ID, which is found engraved on back side of Bumpbar).
Bumpbar attempts to connect, then is connected if pairing is successful. Bumpbar re-enters pairing mode if pairing is unsuccessful.

Press buttons 1, 2, and 10 on second row of Bumpbar simultaneously to forget known connections (see graphic above). Bumpbar then enters low-power hibernation mode.
Enter Bluetooth Menu of host device, select your Bumpbar, and select Forget this Device/Remove Device.

NOTE: Please perform these steps in order as to prevent future re-pairing issues (See Tips & Troubleshooting for more info).

HID Mode: Use when connecting to a traditional KDS System or other standard host device. Bumpbar operates as a keyboard.

KRS Custom Mode: Use when connecting Bumpbar to KRS Bluetooth App on an iOS device.

Enter pairing mode as described in instructions above.
While in pairing mode (it does not matter which pairing mode), perform the three-finger keypress shown above to enter desired Operation Mode.
Bumpbar then enters hibernation mode (you will hear a three-beep sequence).
Re-enter pairing mode. LED flashes blue for HID Mode and Violet for KRS Custom Mode.

Enter Local Configuration Mode: While Bumpbar is connected to host device, press Buttons 2 + 4 on second row simultaneously (shown in graphic above) to enter Local Configuration Mode. The following options can be configured while in this mode:
- NOTE: Mode 4 (custom configuration) is currently unavailable, and Mode 5 is a Serial Communication-only mode and is not compatible with Bluetooth^® Bumpbar.

Change Modes: Bluetooth^® Bumpbars have five built-in Modes (preset button configurations). Refer to the graphic above to change to desired Mode.
Change Lock Sound: On many KDS Systems, receiving an order triggers a Lock Button (Caps Lock, Num Lock, or Scroll Lock), which makes Bumpbar sound a loud beep for 2 seconds. Refer to graphic above to change desired Lock Sound or turn off Lock Sounds entirely.
Turn on/off Button Chirp: Bumpbar chirps each time a button is pressed. To turn on or off this chirp, press Button 9 or 10 on first row, respectively.

Save/Exit Local Configuration Mode: Once all desired changes have been made, press Buttons 2 + 9 on second row simultaneously to save and exit Local Configuration Mode.

If host device becomes unavailable after pairing (host device is powered off, in sleep mode, restarting, etc.), Bumpbar automatically enters pairing mode for 90 seconds. If host device becomes available within this time, Bumpbar automatically reconnects to host device.
If after 90 seconds host device remains unavailable, Bumpbar enters low-power hibernation mode. Once Bumpbar enters hibernation mode, press any button on Bumpbar to wake. If host device is available, Bumpbar automatically reconnects.

Re-pairing to Previous Host Device: If attempting to re-pair Bumpbar to a previous host device in which Bumpbar was forgotten in the Bluetooth options of host device but was not first disconnected via the Bumpbar (using three button “Forget Bluetooth Connection” command shown in graphic above), the first re-pair attempt fails. Simply attempt pairing again in host device's Bluetooth menu, or in the case of Bumpbar improperly connecting to host device (Bumpbar stuck between connecting and pairing), press Forget this Device/Remove Device in Bluetooth menu of host device and re-attempt pairing.
Lock Sounds Beep Twice: When Bumpbar's batteries run low, Lock Sounds occurs twice (two one-second beeps instead of one two-second beep). Replace Bumpbar's AA batteries soon.
Increase Battery Life: Bluetooth^® Bumpbar should operate for one year (or longer) on a single set of 2x AA alkaline batteries but can be configured to conserve battery by turning off Lock Sounds and Button Chirps (see How to Configure Bluetooth^® Bumpbar for instructions).
