Key Features:

•
Based on Bluetooth 4.0 (Bluetooth Low Energy or BLE) with reduction in power consumption and fast connection time.
•
Works with all types of hosts including MacOS, iOS (iPad & iPhone), Android tablets/smartphones, all versions of Windows and Linux as long as
they have Bluetooth 4.0.
•
Compatible with all types of USB keyboards including those with a built-in hub (e.g., Happy Hacking v1, DAS, Apple, Dell, IBM/Lenovo) and
keyboard/trackball combos (both the keyboard and trackball will work). For keyboards with a built-in hub, there can be only one other device
connected to it.
•
Most media keys on keyboard will work including Volume +/-, Mute, Play/Stop, Previous/Next, Browser, Calculator, Home, Help, Search and
Sleep. The handling of those keys varies greatly by the host. Programmable keys (for example, those marked as G1, G2, ... on some Logitech
keyboards) will not work since they need customized device driver.
•
Many keyboard-emulating USB devices will work if they appear as keyboards in the operating system. Those include keypads, foot pedals, bar
code readers, magnetic strip readers, and PS2 to USB adapters. Most 2.4G wireless dongles (e.g., Logitech Unifying Adapter) will also work.
•
No keycode pairing: pairing just works without typing in any code.
•
Advanced Firmware features:
o
Timers: periodically send a key, mouse movement or macro. There can be up to 4 timers.
o
Key mappings: you can map any key to another key, to mouse movement or to a macro. There are built-in mappings to turn a Qwerty
keyboard into a Dvorak or Colemak keyboard with one simple command.
o
Macro: a sequence of keys and/or mouse movements used in key mappings or timers.
1. LED indicators:
Green LED (for keyboard/mouse status)
When there are keystrokes or mouse movements, the LED will blink to indicate activities. This is useful in diagnosing problems.
Blue LED (for Bluetooth connection status)
Blinks normal (once per second) when the adapter is not connected to a host.
Blinks slowly (once per 2 seconds) when the adapter is connected to a host.
Blinks fast (twice per second) when the adapter is in command mode.
2. Mode button: short press once to turn on/off Bluetooth. Press and hold for 2 seconds to enter command mode. Press and hold for 10 seconds to reset all
settings to factory default. Use set bt in command line to enable/disable Bluetooth in startup.
3. When plugged into a laptop, the USB male port shows up as a composite keyboard/mouse device. Any keystrokes or mouse movements will be output
to this port. So this is effectively a USB to USB bridge where you can re-map any key and set up macros and timers.
4. If the adapter is not connected to a host, during the first 30 seconds after turning on, it will advertise its present and become available for pairing. Follow
the process below to pair:
•
Turn on the adapter with or without a keyboard connected. Blue LED should start flashing normally (once per second).
•
On the host, search for Bluetooth devices. The name of the adapter is ADAPTER_nnnn where nnnn is the last 4 digits of its MAC address.
•
When the host finds the adapter, select it and do "pair". There is no need for any pairing code. If pairing succeeds, the adapter will then be
connected to the host and ready to be used. Blue LED flashes slowly.
Pairing is done only once. Next time when the adapter is turned on, it will connect to the paired host if it is available.
If you cannot find the adapter in the host's list of Bluetooth devices, make sure the host has BT 4.0 and up. If the adapter is listed but fails to pair,
make sure the host supports HID keyboard. Some low-cost phones/tablets supports only Bluetooth earphones but not keyboards.
