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 CC2543­CC2544 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.
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.
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.
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.
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:
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.
In the Remote mode all the parameters for the current PER test must be set up before the test begins (go to step 10).
No more actions are needed from the user for the master device to work.

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.

SmartRF Studio allows you to configure the radio,
10. Frequency Selection
When the Remote mode is chosen, a series of settings must be configured to set up the link for the PER test. The frequency must be selected first (the selectable frequency range is from 2402 MHz to 2480 MHz). Move the joystick up or down to change the frequency (channel) and press S1 to confirm the choice.
13. Number of Packets
The total number of packets to be sent for each run can be set to 100, 1000, 10000, 100000 and
1000000. Move the joystick up or down to change the number of packets and press S1 to confirm the choice.
11. Modulation Setup
There are 7 different modulation schemes available. The different bitrates are 250 Kbps, 500 Kbps, 1Mbps and 2 Mbps. MSK modulation is available for 250 Kbps and 500 Kbps data rate while GFSK has all of the mentioned above. Move the joystick up or down to change the scheme and press S1 to confirm the choice.
14. LNA Gain
For the 2Mbps data rates the AGC is enabled, while for lower rates the LNA gain must be set to HIGH or LOW. Move the joystick up or down to change between LOW and HIGH gain and press S1 to confirm the choice. After confirming the last choice the configuration packet will be sent to the Master device and the PER test begins.
12. Packet Length
The packet length can be set to 10, 16, 32 or 63 bytes. Move the joystick up or down to change the packet length and press S1 to confirm the choice.
15. Results I
The packet error rate (PER) is presented as the sum of lost packets and packets with CRC error per thousand. The received signal strength indication (RSSI) is presented as a running average of the five last samples. The number of received packets is continuously updated on the LCD display while the test is running.
13. Results II
When the test is complete a small downward facing arrow will show in the bottom right of the LCD screen. This indicates that the test is complete and that there is an additional results screen “below”. Move the joystick up and down to jump between the two test result screens. Press the S1 button to exit the test results.
14. Repeat Test
After exiting the test results the user is presented with two choices. If “Restart Test” is chosen the same test as previously run will be repeated. The test can also be restarted at any time during the test by pushing the S1 button. Move the joystick up or down to switch between the two commands and press S1 to confirm the choice.
Additional Tools and Links
SmartRF™ Studio
run RF performance tests, and run link tests between the two SmartRF05EBs.
SmartRF Flash Programmer
Texas Instruments has a simple tool which can be used to program and flash the CC2545.
15. New Test
If “New Test” is chosen the application will return to setting up the configuration for a new test, starting at frequency selection. The test can also be stopped at any time during the test by pushing on the joystick like a button.
IAR Embedded Workbench
To develop software, program, and debug the CC2545, you should use IAR Embedded Workbench for 8051.
