CC2540 Evaluation Module Kit Quick Start Guide

Opening the Box and Running the Bluetooth® Low Energy SimpleBLE Demo Application

1. Kit Contents

 2 x CC2540 Evaluation Modules

 2 x Pulse W1010 Antennas

 Documentation

The kit is FCC and IC certified and tested/complies with

ETSI/R&TTE over temperature from 0 to +35°C. The

antenna, W1010 from Pulse, is a ¼ wave dipole antenna with

2 dBi gain.

FCC/IC Regulatory Compliance

FCC Part 15 Class A Compliant

IC ICES-003 Class A Compliant

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 two

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.

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

connector. If not properly connected, you might

see reduced RF performance.

Next, mount the CC2540EMs

firmly on to connectors P5

and P6 on the

SmartRF05EB.

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.

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”.

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.

7. 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 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.

8. 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 should 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.

9. 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 central 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,

giving Disconnected Reason: 22.

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.

10. Connected Operations 11. Read / Write Data 12. 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.
