Select the folder where you want to save the project and click OK.5. BLE projects use a public device address set in the BLE component GUI to advertise and scan,depending on the role: peripheral or central mode. If there are other kits in close proximity, whichhave the same public device address, then wrong devices may be connected or connections canfail. To prevent this, you can change the Public device address (and preferably Device name)in the BLE component. To do this, double-click the BLE component in TopDesign, go to the GAPSettings tab, and choose the General setting. Add the desired public device address (non-zero)and device name in the respective fields, as shown in Figure 4-2. Click OK.Alternatively, you can select the 'Silicon generated' device address by selecting the check box. This way, the BD address is generated using the silicon ID, unique to each silicon. Click OK.

CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 46Example ProjectsFigure 4-6. Connect Device From PSoC Creator and ProgramNote: As stated previously, the BLE Pioneer kit supports both Cypress BLE devices: PSoC 4 BLEand PRoC BLE. Thus, there are two versions of each of the kit example projects demonstrating thesame functionality. Projects named with the prefix PSoC_4_BLE_ work with the PSoC 4 BLE Moduleplaced on the baseboard. Projects named with the prefix PRoC_BLE_ work with the PRoC BLEModule placed on the baseboard. Ensure that the correct module is placed on the baseboard beforeprogramming the device with the corresponding kit example projects.The description, hardware configurations, and verification method of the kit example projectsexplained in the following sections are valid for both PSoC 4 BLE and PRoC BLE devices. Unlessexplicitly mentioned, the theory and usability for these example projects should be considered thesame for both the modules/devices.This document refers to the BLE Pioneer kits, dongle, and PC/mobile as BLE Central or peripheraldevices. A BLE Central device is normally the master and requests/commands data from theperipheral device. BLE-enabled phones and PCs are one such example. BLE peripheral devices, onthe other hand, store the actual data and send it to central devices when requested. Examplesinclude BLE-enabled sensors, proximity beacons, and so on.
CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 47Example Projects4.2 CapSense Slider and LED4.2.1 Project DescriptionThis project demonstrates BLE connectivity between the BLE Pioneer kit (acting as a peripheral andserver device) and BLE dongle or mobile device running the CySmart application (acting as a centraland client device). This project demonstrates following:■Advertisement with timeout■Connection with any BLE Central device■Two custom services in single profile■Data transfer over BLE custom service using notifications, read, and write■Low-power mode implementation for battery operationThe BLE profile in this project consists of two BLE custom services: CapSense and RGB LED. TheCapSense service consists of one custom characteristic, termed as CapSense Slider. TheCapSense slider characteristic is used to send one byte data, ranging from 0 to 100, as notificationto the client device. This data is the finger location read by the CapSense component on the five-segment slider (CSS1) present on the kit. This characteristics supports notification, which allows theBLE server to send data to the connected client device whenever new data is available.The RGB LED service also consists of one custom characteristic, termed as RGB LED Control.This characteristic supports two operations, read and write, through which the connected clientdevice can read data as well as write a new value to the characteristic. This data has four byte val-ues indicating red, green, blue, and intensity values for the onboard RGB LED.These properties for the custom service/characteristics are configured in the BLE component underthe Profiles tab, as shown in Figure 4-7.Figure 4-7. Attributes Configuration in BLE Component for Custom Services
CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 48Example ProjectsThe project consists of the following files:■main.c/.hThese files contain the main function, which is the entry point and execution of the firmware appli-cation. It also contains function definition for initialization of the system and reading the CapSense slider data from the CapSense component.■BLEApplications.c/.hThese files contain all the macros and function definitions related to BLE communication and operation. It contains the event callback function definition that is registered with the BLE compo-nent startup and used by the component to send BLE-related events from the BLE stack to the application layer for processing. It contains a method to send CapSense notifications to the client device and process the Read and Write commands on the RGB LED characteristic by the client device. It updates the BLE Connection parameter, which is important for low-power mode usage.■HandleLowPower.c/.hThese files contain the function to handle low-power mode. This function is continuously called in the main loop and is responsible for pushing the BLE hardware block (BLESS) as well as the CPU to Deep Sleep mode as much as possible. The wakeup source is either the BLE hardware block Link Layer internal timer or the interrupt from the user button press (SW2). This allows for very low power mode implementation and operation using a coin cell.Additionally, the PRoC BLE version of this project consists of the RGB_PRSm.c/.h file, which con-tains the function to drive the software-based PrISM method and drive the color and intensity on theRGB LED.This is the default firmware that comes in the BLE modules shipped with the kit.Two projects demonstrate this functionality on two different devices: ■PSoC_4_BLE_CapSense_Slider_LED works with the PSoC 4 BLE Module■PRoC_BLE_CapSense_Slider_LED works with the PRoC BLE Module. The PSoC 4 BLE project implements RGB color and intensity control using the PRiSM componentwhereas the PRoC BLE uses the software implementation of the PRiSM mode.

This meansthat the firmware role was set to be a BLE peripheral and server; another device such as theCySmart PC tool or CySmart mobile application will connect to it and collect the data.This example project demonstrates the BLE central and client mode where it will scan for a periph-eral device, connect to it, and send commands. In this project, the BLE Pioneer kit scans and auto-connects to a particular peripheral device supporting Immediate Alert Service (IAS). Whenever theperipheral with a predetermined address is found, a connection request is sent followed by discover-ing the attributes. When the discovery is over, you can send one of the three alert levels to the BLEperipheral device over the IAS. This is done by pressing the SW2 button on the BLE Pioneer kit andcycling through the alert levels.The BLE central project supports low-power mode operation, where the firmware supports BLESSand CPU Deep Sleep mode whenever possible. The system remains in deep sleep when discon-nected. Press SW2 to wake up the system and start scanning (blinking blue LED). The scanningtimeout interval is set to 30 seconds. If the particular BLE peripheral device is found advertisingbefore timeout, a connection is made (blue LED always ON). If no such device is found, then the

Press SW2 again to wake thesystem and restart scanning.To aid in evaluation, the BLE peripheral project with the particular BD address is provided in thesame workspace. This peripheral project supports IAS and has fixed BD address that the centraldevice will recognize and auto-connect to. This peripheral project is programmed on the BLE dongleand powered through the USB port of PC. The received alert levels (No, Mid, and High alert) on theBLE dongle are represented by different LED status. No Alert is represented by LED OFF, Mid Alertby blinking LED, and High Alert with LED always ON. Upon each successive button press on theBLE Pioneer kit, the LED state on the BLE dongle changes in a circular fashion.Two projects demonstrate the BLE Central functionality on the two devices:■PSoC_4_BLE_Central_IAS works with the PSoC 4 BLE Module. ■PRoC_BLE_Central_IAS works with the PRoC BLE Module. Additionally, the BLE_Dongle_Peripheral_IAS project is to be programmed on the dongle. Thisproject is present in both the PSoC_4_BLE_Central_IAS and the PRoC_BLE_Central_IAS work-space and can be used to program the dongle separately. Note: If the dongle is programmed with the BLE_Dongle_Peripheral_IAS example, it will not workwith the CySmart PC utility.

This is the default firmware that comes in the BLE dongle shipped with the kit.This project additionally demonstrates LED brightness control via a custom BLE profile, which workswith the CapSense slider example explained in CapSense Slider and LED on page 47. The device will scan for the peripheral acting as a CapSense slider and LED device, and connect toit automatically. This is achieved by filtering the advertisement packets for the CapSense Sliderservice data, which will be sent by the CapSense slider example. Then, it will enable slidernotifications and process the received notifications. Whenever CapSense detects activity, it willnotify the finger location to the dongle; the dongle will update the LED brightness using PWM.The custom client LED control will be stopped if the CySmart PC tool acquires the dongle. Thedongle will enter the CySmart emulator mode, in which it will process all BLE commands astriggered by the user via the tool. The project uses custom command/event protocol to exchangedata between the CySmart PC tool and the BLE component via a USB-CDC interface. It uses theCypress USB-UART bridge functionality from the PSoC 5LP-based KitProg module described inUsing PSoC 5LP as USB-UART Bridge on page 115.Note: This project is meant only for the PRoC BLE device and works on the dongle hardware.

Swipe your finger on the CapSense slider and check the LED brightness variation on the dongle.4.6 Direct Test Mode (DTM)4.6.1 Project DescriptionBluetooth Core specification (v4.0 and later), Volume 6, Part F defines Direct Test Mode (DTM) as amethod to test the BLE PHY layer and provide a report back to the tester. It uses one of the twomethods, over Host Controller Interface (HCI) or through a two-wire UART interface.Device under test (DUT) is the BLE system that is to be tested (for example, BLE Pioneer kit). WithDTM, the RF performance of the BLE system can be verified during development or in productionline. The environment consists of the DUT and a tester. The tester has two parts; the upper testersends commands through one of the two methods (HCI or two-wire UART) and the lower tester per-forms the corresponding action over the RF link. The tester compares the command sent over HCIand the response received over RF, and provides a result of the performance.Figure 4-67. Direct Test Mode (DTM) SetupThe BLE component allows configuring the device in DTM by enabling the HCI. The appropriateresponse to commands from the tester are performed by the BLE stack and does not involve sepa-rate application handling. The only task is to start the BLE component and call the API to process theevents.DUTUpper TesterLower TesterRF (2.4 GHz)HCI/UART
CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 85Example ProjectsThe HCI is enabled in the BLE component under the General Settings. Note that when the HCImode is selected, all other tabs are hidden and cannot be configured. This is because in HCI mode,there are no upper layer processes. On enabling HCI mode in the components, the componentsautomatically reserves a UART block to allow communication between the tester and BLE stack.The UART exposes the pins that can be assigned in Design Wide Resource > Pins. The onlyoption to be configured for HCI mode is the baud rate and the pins for communication with the tester.Figure 4-68. HCI Mode in BLE ComponentMany companies develop BLE testers for Direct Test Mode. It is also possible to create PC-basedsoftware tools that will send HCI commands over serial communication links.For PC-based software, the serial communication link is the COM port, which is enumerated by Kit-Prog on PSoC 5LP of the BLE Pioneer kit. In such a case, the UART pins in PSoC 4 BLE/PRoC BLEshould be assigned to P1_4 and P1_5. These pins are hardwired to pins on PSoC 5LP and allowsUSB-UART data communication between the PC tool and the BLE device.For separate BLE testers, the serial communication is mostly over the RS232. To test with thissystem, an external RS232 voltage translator is required, such as Digilent's Pmod RS232. Thistranslator will modify the signal level of the serial communication between the BLE device and theRS232 port on the tester. The UART pins of the BLE device can be assigned to P0_0 and P0_1 andthe header J5 can be used to connect to the RS232 translator.
CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 86Example ProjectsFigure 4-69. J5 Header to Interface RS232 Translator4.6.2 Hardware ConnectionFor DTM test mode, it is recommended to use SMA connectors and connect the tester and DUTusing a SMA to SMA connector cable. This ensures that there is minimum interference to RFcommunication between the DUT and tester, and the performance measured is the true RFperformance of the device. The BLE Pioneer kit module with SMA connector (CY8CKIT-141 PSoC 4BLE) is available separately and can be ordered from the Cypress web page.Four UART pins are exposed when HCI mode is selected in the BLE component. These pins shouldbe assigned to allow communication with the external tester. The connection depends on the testerbeing used.If the tester is a PC-based software and communicated with HCI over serial link, then the onboardPSoC 5LP on the BLE Pioneer kit can act as the USB-UART bridge. The KitProg on the PSoC 5LPenumerates as a USB-UART interface and opens a COM port in the PC. This COM port is then usedby the software tool to communicate commands to the BLE device. In this case, the UART pinsshould be assigned as follows. The UART for HCI communication exposes hardware flow control lines CTS and RTS. They caneither be connected to the hardware control lines of the tester or CTS connected to ground for oper-ation without hardware flow control.If the tester is an external hardware tester (CBT), then connect any of the RS232 voltage translatorsto header J5 on the BLE Pioneer kit. The UART pins should be assigned as follows.Table 4-3. UART Pin Assignment for PC Software TesterUART Pins Pin AssignedRX P1_4TX P1_5RTS P1_6CTS P1_7

Programming should complete successfully.3. Connect the Serial link, UART or RS232 to the tester.4. On the software tool for tester, configure the UART communication with the correct COM port and baud rate, as set in the BLE component.5. Start the test.

CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 103Hardware5.1.9 Cypress Ferroelectric RAM (F-RAM)The baseboard contains an F-RAM device (FM24V10) (see Figure 5-17) that can be accessedthrough I2C lines P5[0] and P5[1] of the PSoC 4 BLE/PRoC BLE device. The F-RAM is 1-Mbit(128 KB) with an I2C speed up to 1 Mbps. The I2C slave address of the F-RAM device is seven bitswide, and the LSB two bits are configurable through physical pins and are hardwired to 00 on theboard. By default, the address of the F-RAM device used on the board is 0x50. This address can bemodified by changing the R32/R36 and R33/R37 pairs. The operating voltage range of the F-RAM isbetween 2 V and 3.6 V. To prevent the application of 5 V from the adjustable LDO regulator on theboard, a MOSFET based protection circuit similar to the one used for the 3.3-V rail is connectedbetween the output of the regulator and the VDD pin of the F-RAM. The protection circuit cuts off thepower to the F-RAM when the output of the regulator is greater than 3.6 V.Figure 5-17. Schematics and Board Highlight of F-RAM
CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 104Hardware5.1.10 Serial Interconnection Between PSoC 5LP and BLE ModuleThe PSoC 5LP onboard programmer is also a USB-Serial interface, It supports USB-UART andUSB-I2C bridges (see Figure 5-18). The pull-ups resistors on I2C bus are enabled when the protocolis selected from user interface (like bridge control panel). The USB-Serial pins of the PSoC 5LP arealso available on the Arduino header; therefore, the PSoC 5LP can be used to control Arduinoshields with the SPI/I2C/UART interface. Refer Using PSoC 5LP as USB-UART Bridge on page 115and Using PSoC 5LP as USB-I2C Bridge on page 126 for more information on how to use theseserial interconnections Figure 5-18.
