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 Supply1 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. 1 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 Once the connection has been established and service discovery is complete, you can perform the following operations using joystick U1 on the central device:  Read / Write Data – U1 UP  RSSI Monitoring – U1 DOWN  Connection Parameter Update – U1 RIGHT  Terminate Link – U1 IN (towards the board) 11. Read / Write Data 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. The peripheral’s LCD should display the written value each time this is done. Bluetooth low energy is an ideal technology for transmission of small amounts of data between two devices while consuming very little power, as is demonstrated here. Continuing to press up on the joystick will alternate between reads and writes, with the value incrementing each time. 12. Monitor RSSI Pressing down on U1 will turn on RSSI (received signal strength indication) monitoring. The RSSI will be displayed on the LCD in units of negative dBm. If the boards are moved farther apart from each other, the RSSI will drop (since the value is negative, a higher number means lower RSSI). If they are moved closer together, the RSSI should rise. Pressing down on U1 again will turn off RSSI monitoring. 13. Connection Parameter Update Pressing right on U1 will send a connection parameter update request to the peripheral to use a longer connection interval. This will result in much longer latency when performing data reads and writes; however the power consumed by both devices is significantly reduced. 14. Terminate Link Pressing U1 in towards the board will terminate the link. The peripheral will return to an advertising state. The central device will display a “Reason” code, which indicates why the disconnection occurred (values are defined in the BLE stack API). In this case, the reason code of 22 indicates that the link termination was initiated by the central device. In the event that the peripheral device goes out of range or has power disconnected from it, you will see a reason code of 8 which indicates that a link timeout has occurred. You can now perform device discovery and re-connect to the peripheral if desired. 15. SimpleBLE Demo Source Code The project and source code files for these applications (as well as many others) are included with the Bluetooth low energy (BLE) stack from Texas Instruments, which can be downloaded at www.ti.com/blestack. The two projects implementing this demo are called SimpleBLECentral (CC2540EM Master configuration) and SimpleBLEPeripheral (CC2540 Slave configuration). These can be modified as desired, and should provide a good framework for developing your own custom BLE applications. More details on these projects can be found within the BLE Software Developer’s Guide, which is included with the stack. Additional Tools and Links BLE Packet Sniffer A CC2540 USB Dongle (not included) can be used as a BLE sniffer and monitor packets while the SimpleBLE Demo is running. The SmartRF Protocol Packet Sniffer application can be downloaded from www.ti.com/tool/packet-sniffer. SmartRF™ Studio SmartRF Studio allows you to configure the radio, run RF performance tests, and run link tests between the two SmartRF05EBs. SmartRF Studio can be downloaded from www.ti.com/smartrfstudio SmartRF Flash Programmer Texas Instruments has a simple tool which can be used to program and flash the CC2540. The SmartRF Flash Programmer application can be downloaded from www.ti.com/tool/flash-programmer BTool BTool is a Windows application that allows you to control a central device using the serial interface and perform various BLE functions while connected to a peripheral device. BTool is included as part of the installation of the BLE stack (see “Useful Links” to the right). IAR Embedded Workbench To develop software, program, and debug the CC2540, you should use IAR Embedded Workbench for 8051.
