HID Keyboard

Zebra Aurora Focus JavaScript Programmer's Guide

HID Keyboard

Enable the HID keyboard to use the device in HID keyboard mode. Assign a string, single button, key, and modifier combination. You can also add a pause between keystrokes. All of those can be leveraged into a single assignment.

hid?: (string|(IHIDCombinationResult| IHIDPauseResult|HIDKey|string)[]);

An additional helper object,

HID

is available to simplify HID usage.

HID

properties are described in the following table.

Helper Object HID Properties
Property	Description
HID.key	Gives access to a list of available keys.
HID.combination	Allows the creation of a key and modifiers combination.
HID.pause	Allows a pause between consecutive keystrokes to be created.
HID.modifier	Gives access to a list of available key modifiers.

HID.pause argument must be between 0 and 25000 ms.

HID.combination allows you to press, at the same time, a key and up to 8 different modifiers.

HID.combination produces a series of consecutive keystrokes with the same modifiers when used with more than one key.

Keystroke delay and preferred keyboard layout can be changed through

Communication

tab in the device settings.

If that property is not assigned, nothing is printed.
