4. Set Jumper P11
Find jumper P11 on the top side of each
SmartRF05EB. This jumper is used to set the
power source for the board. Set P11 to "1-2" if
you are using battery power. Set P11 to "2-3" if
you are using USB or an external power supply.
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 pressed
in like a button. Each movement performs
different actions depending on the state of the
device.
2. Hardware Setup
Connect the antennas to the SMA connector on
the RF evaluation boards. Tighten the antenna's
screw firmly on to the SMA connector. If not
properly connected, you might see reduced RF
performance. Next, mount
evaluation modules (CC2540EMs)
connectors P5 and P6 on the SmartRF05EB.
Make sure that the boards are pressed firmly
into the connectors.
5. Turn on the Boards
Once you have set P11, find switch P8 on the
top side of each SmartRF05EB. To power up
the boards, flip the switch from the "OFF"
position 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. Power Options
There are several ways of applying power to
the SmartRF05EB.

2 x 1.5 V AA Batteries

the CC2540
USB
on to 
External Power Supply
For the batteries and USB, there are voltage
regulators on the SmartRF05EB that will set
the on-board voltage to 3.3 V. The external
power supply should set a voltage that does
not exceed 3.3 V.
Note that there should only be one active
power source at any one time.
6. Start-up Screen
One of the CC2540EMs will be pre-loaded
with the SimpleBLECentral application, while
the other will be pre-loaded with the
SimpleBLEPeripheral application. The LCD
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
towards the board
(push it in like it is a
button). Once the
connection
established,
central device will
automatically perform service discovery on the
peripheral using the BLE GATT protocol. This
should complete within a few seconds.
discovered the The two LCD screens should appear as in the
images below, with the central still displaying
the peripheral's address and the peripheral
seen on the having changed
