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.
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 need two CC2545EMs mounted on
SmartRF05 Evaluation Boards (SmartRF05EB -
Rev 1.8.1 or later). Two SmartRF05EBs are
included in the CC2543-CC2544 Development
Kit.
More information about the SmartRF05EB can
be found in
The CC2545EM boards can also be plugged into
a battery board (see
) for
standalone operation.
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.
USB (5V)
2 x 1.5 V AA Alkaline Batteries
External Power Supply (4-20V)
For the batteries, USB and external power supply
via the DC jack, there are voltage regulators on
the EB that will set the on-board voltage to 3.3 V.
Warning!
To minimize risk of injury or property
damage, never use rechargeable batteries to power
the board. Always select a power source that is
suitably rated for use with this EVM,
not exceeding
20 VDC, with a current output rating between 0 and
1500 mA. Note that there should only be one active
power source at any one time.
5. Power the Boards
Locate
the
power
source header P11 just
above the LCD on the
EB. Connect pins 1 and
2 if you are using
battery power. Connect
pins 2 and 3 if you are using USB or an external
power supply.
Once you have set P11,
find switch P8 just next to
the DC jack on the EB. To
power up the boards, flip
the switch from the “OFF”
position to “ON”.
Do not leave the 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.
