CC2545EMK Quick Start Guide
Opening the Box and Running the Packet Error Rate Test Application
1. Kit Contents
• 2 x CC2545 Evaluation Modules (EM)
• Documentation
The RF boards in this kit are FCC and IC
certified and tested/complies with ETSI/R&TTE
over temperature from 0 to +35°C. There is an
on-board PCB antenna on the evaluation
module. This kit is a
Caution! The kit contains ESD
sensitive components. Handle with
care to prevent permanent damage.
2. Hardware Requirements
To run the example described in this Quick Start
Guide, you would need either two CC2545EMs
mounted on SmartRF05 Evaluation Boards
(SmartRF05EB - Rev 1.8.1 or later).
SmartRF05EB is included in the CC2543-
CC2544 Development Kit.
More information about the SmartRF05EB can
be found in www.ti.com/lit/swru210.
The CC2545EM boards can also be plugged
into a battery board (see www.ti.com/tool/soc-
bb) for standalone operation.
The source code for the PER test can be
downloaded from the CC2545DK product
page (www.ti.com/tool/cc2545dk).
3. Hardware Setup
Mount the CC2545EMs 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.
4. Power Options
There are several ways of applying power to the
SmartRF05EB.
• 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
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.
Warning! To minimize risk of personal injury or
property damage, never use rechargeable
batteries to power the board.
5. Power the
Boards
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 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”.
Do not leave EVM powered when
unattended.
6. Start-up Screen
The CC2545EMs are pre-loaded with a
Packet Error Rate (PER) test application.
The LCD screens on the two SmartRF05EBs
should display the messages below:
7. Choosing Mode
The application can be used between two
CC2545EM’s. There are two operating modes:
“Remote” and “Master”.
After button S1 is pushed at the start up screen,
the mode selection screen (showed below) will
appear. The Remote mode is shown by default.
Press the joystick up and down to change
between master and remote mode and press
button S1 to confirm.
In the Remote mode all the parameters for the
current PER test must be set up before the test
begins (go to step 10).
8. Master Mode (Beacon)
In “Master” mode, the radio will repeatedly (once
every 10 milliseconds) send out a “beacon”
signal (250 kbps, GFSK modulation, 160 kHz
deviation, 2402 MHz) and listen for a response
from the remote device. The Green LED1 will
blink continuously.
No more actions are needed from the user for
the master device to work.
9. Master Mode (PER test)
Once the beacon is acknowledged by the
“Remote”, the actual PER test begins. The PER
test configuration is included in the payload of
the acknowledge packet. The Master device
extracts this information and configures the radio
parameters accordingly. During the PER test,
packets are sent at a fixed repetition rate of 10
msec.
During the test the number of sent packets will
be updated on the LCD display as well as the link
status between the Master and Remote device.
