Kit Contents2 x CC2541Evaluation Modules2 xPulseW1010AntennasDocumentationThe kit isFCC and IC certified andtested/complies with ETSI/R&TTEovertemperaturefrom0 to +35°C. The antenna,W1010 from Pulse,is a ¼ wave dipole antennawith 2 dBi gain.Caution!Thekit containsESDsensitive components. Handle withcare to prevent permanent damage.2.HardwareRequirementsThe CC2541EMK is an add-on kit to theCC2540DK. To run the example described inthis Quick Start Guide, you would needtwoSmartRF05 Boards (Rev 1.8.1 or later). Theseboards are included in the CC2540DK (andnot in the CC2541EMK).More information about the SmartRF05EB canbe found inwww.ti.com/lit/swru210.The CC2541EM boards canalsobe pluggedinto a battery board (seewww.ti.com/tool/soc-bb) forstandalone operation.3.HardwareSetupConnect the antenna to the SMA connector onthe CC2541 evaluation module (CC2541EM).Tighten the antenna’s screw firmly on to the SMAconnector. If not properly connected, you mightsee reduced RF performance.Next, mount the CC2541EMsfirmly on to connectors P5and P6 on theSmartRF05EB.Caution!To minimize risk of injury, avoidtouching components during operation ifsymbolized as hot.4.Power OptionsThere are several ways of applying power to theSmartRF05EB.2 x 1.5 V AAAlkalineBatteriesUSBExternal Power SupplyFor the batteries and USB, there are voltageregulators on the SmartRF05EB that will set theon-board voltage to 3.3 V. The external powersupply should set a voltage that does not exceed3.3 V.Note that there should only be oneactive power source at any one time.Warning!To minimize risk of personal injury orproperty damage, never use rechargeablebatteries to power the board.5.Power theBoardsFind jumper P11 onthe top side of eachSmartRF05EB. This jumper is used to set thepower source for the board. Set P11 to “1-2” ifyou are using battery power. Set P11 to “2-3” ifyou are using USB or anexternal power supply.Once you have set P11,find switch P8 on the topside of eachSmartRF05EB. To power up the boards, flip theswitch from the “OFF” position to “ON”.Do not leave EVM powered whenunattended.6.Start-up ScreenOne of the CC2541EMswill be pre-loadedwith the SimpleBLECentral application, whilethe other will be pre-loaded with theSimpleBLEPeripheral application. The LCDscreens on the two SmartRF05EBs shoulddisplay messagessimilar to those below:The “0x…” value displayed on each board isthe device address. EveryCC2541devicehasa unique address.7.Using the JoystickThe SimpleBLEPeripheral application runsautonomously and does not require any userinteraction. The SimpleBLECentral application,however,requires user interaction by means ofjoystick U1. Find joystick U1 on the top side ofthe SmartRF05EB, immediately below the LCD.The joystick has five different movements: it canbe moved up, down, left, right, and it canbepressed in, justlike a button. Each movementperforms different actions depending on the stateof the device.8.Device DiscoveryBefore the two devicescan connect, the centraldevice must firstdiscover the peripheraldevice. To performdevice discovery, pressup on joystick U1 once.The LCD on the centraldevice should display“Discovering…”.After a few seconds, it should display “DevicesFound 1 / <-To Select”. This means that thecentral device successfully discovered theperipheral. Press left on joystick U1 to view theaddress of the peripheral device. Thisaddressshould match the address seen on theperipheral’s LCD.9.Establish ConnectionTo establish aconnection withthe peripheral,press joystick U1in towards theboard (push it inlike it is a button).Oncetheconnection isestablished, the central device willautomatically perform service discovery on theperipheral using theBLEGATT protocol. Thisshould complete within a fewseconds.The two LCD screens should appear as in theimages below, with the central still displayingthe peripheral’s addressand the peripheralhaving changed from “Advertising” to“Connected”:Be careful that you don’t double tap U1 whichwould terminate the connection immediately,givingDisconnected Reason: 22.
