4. Power Options
There are several ways of applying power to the
SmartRF05EB;
 USB (5V through USB plug)
 External Power Supply (see below)
 2 x 1.5V AA Non-Rechargeable Alkaline
Batteries
Voltage regulators on the SmartRF05EB will set
the on-board voltage to 3.3V.

External Power Supply Requirements:
Nom Voltage: 4 to 20 VDC
Max Current: 1500 mA
Efficiency Level V
Warning! To minimize risk of personal injury or
property damage, never use rechargeable batteries to
power the board.
7. Using the Joystick
The SimpleBLEPeripheral application
autonomously and does not require any user
interaction. The SimpleBLECentral application,
however, requires user interaction by means of
joystick U1. Find joystick U1 on the top side of
the SmartRF05EB, immediately below the LCD.
The joystick has five different movements: it can
be moved up, down, left, right, and it can be
pressed in, just like a button. Each movement
performs different actions depending on the state
of the device.

When using an external power supply, make sure it meets the listed requirements in addition to complying with applicable regional product regulatory and
safety certification requirements such as UL, CSA, VDE, CCC, and PSE.
2. Hardware Requirements
The CC2540EMK is an add-on kit to the
CC2540DK. To run the example described in this
Quick Start Guide, you would need
SmartRF05 Boards (Rev 1.8.1 or later). These
boards are included in the CC2540DK (and not in
the CC2540EMK).
More information about the SmartRF05EB can
be found in www.ti.com/lit/swru210.
The CC2540EM boards can also be plugged into
a battery board (see www.ti.com/tool/soc-bb) for
standalone operation.
5. Power the Boards
Locate the power source
header P11 just above
the LCD on the
SmartRF05EB. Connect
pins 1 and 2 if you are
using batteries to power the board. Connect pins
2 and 3 if you are using USB or external power
supply.
Once you have set P11,
find switch P8 just next to
the DC jack on the
SmartRF05EB. To power
on the board, flip the
switch from "OFF"
to "ON".
8. Device Discovery
runs Before the two devices
can connect, the central
device must first
discover the peripheral
device. To perform
device discovery, press
up on joystick U1 once.
The LCD on the central
device should display
"Discovering...".
After a few seconds, it should display "Devices
Found 1 / <- To Select". This means that the
central device successfully
peripheral. Press left on joystick U1 to view the
address of the peripheral device. This address
should match the address
peripheral's LCD.

3. Hardware Setup
Connect the antenna to the SMA connector on
the CC2540 evaluation module (CC2540EM).
Tighten the antenna's screw firmly on to the SMA
two
connector. If not properly connected, you might
see reduced RF performance.
Next, mount the CC2540EMs
firmly on to connectors P5
and P6 on
SmartRF05EB.
6. Start-up Screen
One of the CC2540EMs will be pre-loaded with
the SimpleBLECentral application, while the
other will
SimpleBLEPeripheral
screens on the two SmartRF05EBs should
display messages similar to those below:
The "0x..." value displayed on each board is the
device address. Every CC2540 device has a
unique address.
9. Establish Connection
To establish
connection with
the peripheral,
press joystick U1
in towards the
board (push it in
like it is a button).
Once the
connection
established, the central device will automatically
perform service discovery on the peripheral using
the BLE GATT protocol. This should complete
within a few seconds.

The two LCD screens should appear as in the
images below, with the central still displaying the
peripheral's address and the peripheral having

Be careful that you don't double tap U1 which
would terminate the connection immediately,
