Hardware

quirements

The CC2541EMK is an add

on kit to the

CC2540DK. To run the example described in

this Quick Start Guide, you would need

two

SmartRF05 Boards (Rev 1.8.1 or later)

. These

boards are included in the CC2540DK (and

not in the CC2541EMK).

More infor

mation about the SmartRF05EB can

be found in

www.ti.com/lit/swru210

The CC2541

EM boards can

also

be plugged

into a battery board (see

www.ti.com/tool/soc

) for

standalone operation.

Hardware

Setup

Connect the antenna to the SMA connector on

the CC2541 evaluation module (CC2541EM).

Tighten the antenna’s screw firmly on to the SMA

connector. If not properly connected, you might

see reduced RF performance.

ext, mount the CC2541EMs

firmly on to connectors P5

and P6 on the

SmartRF05EB.

Caution!

To minimize risk of injury, avoid

touching components during operation if

symbolized as hot.

Power Options

There are several ways of applying power to the

Smar

tRF05EB.



2 x 1.5 V AA

Alkaline

Batteries



USB



External Power Supply

For the batteries and USB, there are voltage

regulators on the SmartRF05EB that will set the

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.

Warning!

To minimize risk of personal injury or

property damage, never use rechargeable

batteries to power the board.

Power the

oards

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.

Once you have set P

11,

find switch P8 on the top

side of each

SmartRF05EB. To power up the boards, flip the

switch from the “OFF” position to “ON”

Do not leave EVM powered when

unattended.

Start

up Screen

One of the CC2541

EMs

will be pre

loaded

with the SimpleBLECentral application, while

the other will be p

loaded with the

SimpleBLEPeripheral application. The LCD

screens on the two SmartRF05EBs should

display message

similar to those below:

The “0x…” value displayed on each board is

the device address. Every

CC25

dev

ice

has

a unique address.

Using the Joystick

The SimpleBLEPeripheral application runs

autonomously and does not require any user

interaction. The SimpleBLECentral application,

however,

requires user interaction by means of

joystick U1. Find joys

tick 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

, just

like a button. Each movement

performs different ac

tions depending on the state

of the device.

Device Discovery

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 sho

uld display

“Discovering…”.

After a few seconds, it should display “Devices

Found 1 / <

To Select”. This means that the

central device successfully discovered the

peripheral. Press left on joystick U1 to view the

address of the peripheral device. This

address

should match the address seen on the

peripheral’s LCD.

Establish Connection

To establish a

connection with

the peripheral,

press joystick U1

in towards the

board (push it in

like it is a button).

Once

the

connection is

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 cen

tral still displaying

the peripheral’s address

and the peripheral

having changed from “Advertising” to

“Connected”:

Be careful that you don’t double tap U1 which

would terminate the connection immediately,

Monitor RSSI Once the connection has been established and service discovery is complete, you can perform the following operations using joystick U1 on the central device: Pressing up on U1 will send a read request to the peripheral device. One byte of data will be read, and the value will be displayed. Pressing up again will send a write request, and one byte of data will be written to the peripheral.
