Introduction

This document will guide you through the initial
steps required in order to run the pre programmed
Bluetooth® low energy (BLE) demo application.

You will get familiar with the hardware in the box
and how to interface the remote with different
platforms.

1. Evaluate using dongle. A USB dongle
pre-programmed with firmware acting as
translator between BLE HID and USB
HID is supplied in the kit and works with
most operating system platforms.

2. Evaluate using Windows 8 native.
Windows 8 includes native support for the
BLE HID over GATT profile. Using a
BT4.0 dongle or internal BT4.0 hardware
you can easily connect the Advanced
Remote to your computer.

Hardware Setup

Insert 3xAAA (LR03) batteries in the Advanced
Remote’s battery holder. You are good to go.

Pressing any button on the remote will put it
into advertising mode and make it detectable by
Bluetooth Low Energy capable hosts.

Connect Using Single Mode BT4.0 Low Energy CC2540USB HID Dongle

1. Insert dongle in USB port

The dongle will be enumerated as three USB
Human Interface Device class devices.

 Mouse
 Keyboard
 Consumer control

The LED on the dongle should start blinking red,
indicating it’s scanning for a Bluetooth Low
Energy peripheral which advertises BLE HID
service capabilities.

2. Advertise and connect

Press any number key or consumer control key to
make the device advertise.

The devices will now connect and pair using
JustWorks pairing. The dongle LED should now
blink green when data is received from the
Advanced Remote and otherwise be off.

Long term bonding entries will be stored in both
the Advanced Remote and dongle to speed up
subsequent reconnections.

3. Manage connection and bonds

Pressing SW1 on the dongle will disconnect any
active connection between the dongle and an
Advanced Remote.

Pressing SW2 on the
dongle will erase all
long term bond
information stored on
the dongle.

Pressing this button
will not affect bond
data stored on the
Advanced Remote.

Connect to Windows 8 with BT 4.0 LE (Smart Ready) hardware

1. Make sure LE works

In Device manager, under Bluetooth, make sure
that you see references to Bluetooth LE.

2. Open PC settings

Move your mouse to the lower right hand corner
and click on Settings.

Then click on Change PC settings.

3. Add Advanced Remote

Then click on Devices and Add a device.

4. Select and add the remote

If you have pressed a button on the Advanced
Remote, and it’s not connected to another host, it
will show up in the list of found devices.

5. Enter pairing code

The devices will now pair using Passkey entry.
On your Advanced Remote, enter the 6-digit
passkey displayed on the computer screen.

The Advanced Remote is now paired with
Windows and bond data is stored on both
devices, making reconnection faster and passkey
entry unnecessary.

6. Remove device

A device can be removed from Windows and
bond data deleted by clicking on the device and
then the ( – ) symbol.

Using the Advanced Remote Control

Mouse

keys

Mouse speed

Action keys

1. Advertise and connect

Almost all the keys will make the Advanced Remote
start advertising and be discoverable by hosts
scanning for HID capable BLE devices.

2. Keyboard input

Pressing any number will act as a keyboard input of
that number. The same goes for OK which is Enter,
Back which is Backspace and the four keys
surrounding OK, which act as directional or arrow
keys.

3. Consumer control

Buttons such as Volume, Mute, Play/Pause etc. are
consumer control keys, and will control media
settings on your computer.

4. Mouse input

Holding down the middle button will prompt the Advanced
Remote to interpret your movement of the remote as mouse
input and send this to the computer.

Double clicking the middle button will lock the mouse function.
The left and right buttons act as left and right mouse buttons.

Pressing AV and –/– will decrease and increase mouse
speed.

5. Remove bond information

Pressing the Red action button will remove bonding
information stored on the Advanced Remote. Pairing will have
to be done again, using passkey entry if applicable.

6. Calibrate

Pressing the Blue action button will force the Advanced
Remote to recalibrate the onboard gyroscope and
accelerometer used for motion sensing.
