The board is an open system design, which does not include a shielded enclosure. Due to this reason, the board may cause interference with other electrical or electronic devices in close proximity. In a domestic environment, this product may cause radio interference. In such cases, the user may be required to take adequate preventive measures. Also, this board should not be used near any medical equipment or critical RF devices. The CY8CKIT-042-BLE Bluetooth Low Energy (BLE) Pioneer Kit is intended for use as a development, demonstration and evaluation platform for hardware or software in a laboratory environment. The kit is not intended for general consumer use. Cypress recommends that the kit only be used in a shielded room. Attaching additional wiring to this product or modifying the product operation from the factory default may affect its performance and cause interference with other apparatus in the immediate vicinity. If such interference is detected, suitable mitigating measures should be taken. The CY8CKIT-042-BLE boards contain electrostatic discharge (ESD) sensitive devices. Electrostatic charges readily accumulate on the human body and any equipment, which can cause a discharge without detection. Permanent damage may occur on devices subjected to high-energy discharges. Proper ESD precautions are recommended to avoid performance degradation or loss of functionality. Store unused CY8CKIT-042-BLE boards in the protective shipping package. End-of-Life/Product Recycling The end-of-life cycle for this kit is five years from the date of manufacture mentioned on the back of the box. Contact your nearest recycler to discard the kit.

Open Example Project from PSoC Creator 4. 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, which have the same public device address, then wrong devices may be connected or connections can fail. 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 GAP Settings 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 BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 45 Example Projects Figure 4-6. Connect Device From PSoC Creator and Program Note: As stated previously, the BLE Pioneer kit supports both Cypress BLE devices: PSoC 4 BLE and PRoC BLE. Thus, there are two versions of each of the kit example projects demonstrating the same functionality. Projects named with the prefix PSoC_4_BLE_ work with the PSoC 4 BLE Module placed on the baseboard. Projects named with the prefix PRoC_BLE_ work with the PRoC BLE Module placed on the baseboard. Ensure that the correct module is placed on the baseboard before programming the device with the corresponding kit example projects. The description, hardware configurations, and verification method of the kit example projects explained in the following sections are valid for both PSoC 4 BLE and PRoC BLE devices. Unless explicitly mentioned, the theory and usability for these example projects should be considered the same for both the modules/devices. This document refers to the BLE Pioneer kits, dongle, and PC/mobile as BLE Central or peripheral devices. A BLE Central device is normally the master and requests/commands data from the peripheral device. BLE-enabled phones and PCs are one such example. BLE peripheral devices, on the other hand, store the actual data and send it to central devices when requested. Examples include BLE-enabled sensors, proximity beacons, and so on. CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 46 Example Projects 4.2 CapSense Slider and LED 4.2.1 Project Description This project demonstrates BLE connectivity between the BLE Pioneer kit (acting as a peripheral and server device) and BLE dongle or mobile device running the CySmart application (acting as a central and client device). This project demonstrates following: â Advertisement with timeout â Connection with any BLE Central device â Two custom services in single profile â Data transfer over BLE custom service using notifications, read, and write â Low-power mode implementation for battery operation The BLE profile in this project consists of two BLE custom services: CapSense and RGB LED. The CapSense service consists of one custom characteristic, termed as CapSense Slider. The CapSense slider characteristic is used to send one byte data, ranging from 0 to 100, as notification to the client device. This data is the finger location read by the CapSense component on the fivesegment slider (CSS1) present on the kit. This characteristics supports notification, which allows the BLE 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 client device can read data as well as write a new value to the characteristic. This data has four byte values 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 under the Profiles tab, as shown in Figure 4-7. Figure 4-7. Attributes Configuration in BLE Component for Custom Services CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 47 Example Projects The project consists of the following files: â main.c/.h These files contain the main function, which is the entry point and execution of the firmware application. It also contains function definition for initialization of the system and reading the CapSense slider data from the CapSense component. â BLEApplications.c/.h These 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 component 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. â HandleLowPower.c/.h These 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 contains the function to drive the software-based PrISM method and drive the color and intensity on the RGB 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: â PSoC_4_BLE_CapSense_Slider_LED works with the PSoC 4 BLE Module â 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 component whereas the PRoC BLE uses the software implementation of the PRiSM mode.

When the CapSense service page opens, bring your hand near the sensor wire on the BLE Pioneer kit and see a similar response in the app as a bar graph, as shown in Figure 4-52. Figure 4-52. CapSense Proximity Sensing with PSoC 4 BLE Module 10.To disconnect from the BLE Pioneer kit, return to the device selection screen on the CySmart app. 11. To reconnect to the peripheral, press the user button (SW2) on the BLE Pioneer Kit to restart the advertisement and scan for the device in the CySmart app. 4.4 BLE Central Mode 4.4.1 Project Description The BLE projects described above have been functioning as BLE peripheral devices. This means that the firmware role was set to be a BLE peripheral and server; another device such as the CySmart 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 peripheral device, connect to it, and send commands. In this project, the BLE Pioneer kit scans and autoconnects to a particular peripheral device supporting Immediate Alert Service (IAS). Whenever the peripheral with a predetermined address is found, a connection request is sent followed by discovering the attributes. When the discovery is over, you can send one of the three alert levels to the BLE peripheral device over the IAS. This is done by pressing the SW2 button on the BLE Pioneer kit and cycling through the alert levels. The BLE central project supports low-power mode operation, where the firmware supports BLESS and CPU Deep Sleep mode whenever possible. The system remains in deep sleep when disconnected. Press SW2 to wake up the system and start scanning (blinking blue LED). The scanning timeout interval is set to 30 seconds. If the particular BLE peripheral device is found advertising before timeout, a connection is made (blue LED always ON). If no such device is found, then the CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 73 Example Projects system stops scanning and returns to Deep Sleep mode (LED OFF). Press SW2 again to wake the system and restart scanning. To aid in evaluation, the BLE peripheral project with the particular BD address is provided in the same workspace. This peripheral project supports IAS and has fixed BD address that the central device will recognize and auto-connect to. This peripheral project is programmed on the BLE dongle and powered through the USB port of PC. The received alert levels (No, Mid, and High alert) on the BLE dongle are represented by different LED status. No Alert is represented by LED OFF, Mid Alert by blinking LED, and High Alert with LED always ON. Upon each successive button press on the BLE 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: â PSoC_4_BLE_Central_IAS works with the PSoC 4 BLE Module. â PRoC_BLE_Central_IAS works with the PRoC BLE Module. Additionally, the BLE_Dongle_Peripheral_IAS project is to be programmed on the dongle. This project is present in both the PSoC_4_BLE_Central_IAS and the PRoC_BLE_Central_IAS workspace 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 work with the CySmart PC utility. Reprogram the dongle with the CySmart firmware according to Updating BLE Dongle for CySmart PC Tool on page 33 to use the CySmart PC tool. Figure 4-53.

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 works with 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 to it automatically. This is achieved by filtering the advertisement packets for the CapSense Slider service data, which will be sent by the CapSense slider example. Then, it will enable slider notifications and process the received notifications. Whenever CapSense detects activity, it will notify 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. The dongle will enter the CySmart emulator mode, in which it will process all BLE commands as triggered by the user via the tool. The project uses custom command/event protocol to exchange data between the CySmart PC tool and the BLE component via a USB-CDC interface. It uses the Cypress USB-UART bridge functionality from the PSoC 5LP-based KitProg module described in Using 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.

In addition, the LED control operation can be verified as follows. 1. Power the BLE Pioneer kit through the USB connector J13. 2. Program the BLE Pioneer kit with the CapSense and LED example project described in CapSense Slider and LED on page 47. 3. Connect the BLE dongle to one of the USB ports on the PC. 4. Program the dongle with the BLE_Dongle_CySmart project. See Using Example Projects on page 42 for programming instructions. 5. Press the user button SW2 on both the BLE dongle and the BLE Pioneer kit. The BLE dongle will start scanning and the BLE Pioneer kit will start advertising. 6. Wait for the BLE connection between the BLE dongle and the Pioneer baseboard. The connection success status will be indicated by a 3-second ON state of the red LED followed by the OFF state on the baseboard. 7. 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 Description Bluetooth Core specification (v4.0 and later), Volume 6, Part F defines Direct Test Mode (DTM) as a method to test the BLE PHY layer and provide a report back to the tester. It uses one of the two methods, 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). With DTM, the RF performance of the BLE system can be verified during development or in production line. The environment consists of the DUT and a tester. The tester has two parts; the upper tester sends commands through one of the two methods (HCI or two-wire UART) and the lower tester performs the corresponding action over the RF link. The tester compares the command sent over HCI and the response received over RF, and provides a result of the performance. Figure 4-67. Direct Test Mode (DTM) Setup HCI/UART Upper Tester DUT RF (2.4 GHz) Lower Tester The BLE component allows configuring the device in DTM by enabling the HCI. The appropriate response to commands from the tester are performed by the BLE stack and does not involve separate application handling. The only task is to start the BLE component and call the API to process the events. CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 84 Example Projects The HCI is enabled in the BLE component under the General Settings. Note that when the HCI mode 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 components automatically 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 only option 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 Component Many companies develop BLE testers for Direct Test Mode. It is also possible to create PC-based software 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 KitProg on PSoC 5LP of the BLE Pioneer kit. In such a case, the UART pins in PSoC 4 BLE/PRoC BLE should be assigned to P1_4 and P1_5. These pins are hardwired to pins on PSoC 5LP and allows USB-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 this system, an external RS232 voltage translator is required, such as Digilent's Pmod RS232. This translator will modify the signal level of the serial communication between the BLE device and the RS232 port on the tester. The UART pins of the BLE device can be assigned to P0_0 and P0_1 and the header J5 can be used to connect to the RS232 translator. CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 85 Example Projects Figure 4-69. J5 Header to Interface RS232 Translator 4.6.2 Hardware Connection For DTM test mode, it is recommended to use SMA connectors and connect the tester and DUT using a SMA to SMA connector cable. This ensures that there is minimum interference to RF communication between the DUT and tester, and the performance measured is the true RF performance of the device. The BLE Pioneer kit module with SMA connector (CY8CKIT-141 PSoC 4 BLE) 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 should be assigned to allow communication with the external tester. The connection depends on the tester being used. If the tester is a PC-based software and communicated with HCI over serial link, then the onboard PSoC 5LP on the BLE Pioneer kit can act as the USB-UART bridge. The KitProg on the PSoC 5LP enumerates as a USB-UART interface and opens a COM port in the PC. This COM port is then used by the software tool to communicate commands to the BLE device. In this case, the UART pins should be assigned as follows. Table 4-3. UART Pin Assignment for PC Software Tester UART Pins Pin Assigned RX P1_4 TX P1_5 RTS P1_6 CTS P1_7 The UART for HCI communication exposes hardware flow control lines CTS and RTS. They can either be connected to the hardware control lines of the tester or CTS connected to ground for operation without hardware flow control. If the tester is an external hardware tester (CBT), then connect any of the RS232 voltage translators to header J5 on the BLE Pioneer kit. The UART pins should be assigned as follows.

Program the BLE Pioneer kit with the PSoC_4_BLE_DTM or PRoC_BLE_DTM project, depending on the BLE module used (PSoC 4 BLE or PRoC BLE), as described in Using Example Projects on page 42. 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. The tool will generate the report after the end of the test. This depends on the tester/tool being used. CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 87 5. Hardware This chapter describes the contents of the BLE Pioneer kit hardware and its different blocks, such as the power block, USB connection, Arduino-compatible headers, BLE module connectors, and CapSense slider. 5.1 Pioneer Baseboard 5.1.1 PSoC 5LP An onboard PSoC 5LP is used to program and debug the BLE silicon. The PSoC 5LP connects to the USB port of the PC through a USB mini-B connector and to the SWD interface of the BLE device. PSoC 5LP is a true system-level solution providing MCU, memory, analog, and digital peripheral functions in a single chip. The CY8C58LPxx family offers a modern method of signal acquisition, signal processing, and control with high accuracy, high bandwidth, and high flexibility. The analog capability spans the range from thermocouples (near DC voltages) to ultrasonic signals. For more information, visit the PSoC 5LP web page. See Serial Interconnection Between PSoC 5LP and BLE Module on page 104 for more details. 5.1.2 Power System The power supply system on this board is versatile, allowing the input supply to come from the following sources: â 5-V power from onboard USB connector â 5-V to 12-V VIN power from Arduino shield at J1 â 3.3 V from I/O header J1 â 3 V from CR2032 coin cell CY8CKIT-042-BLE BluetoothÂŽ Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. *A 88 Hardware An adjustable LDO is used to output three different voltage levels (1.9 V, 3.3 V, and 5 V) to power the BLE module.

Note: The typical dropout voltage of the selected LDO is 0.3 V at 500-mA output current. This gives a minimum output of 4.6 V from the input voltage of 5 V from the VBUS. This drop also takes into account the voltage drop across the Schottky diode connected at the output of the LDO to protect against voltage applied at the output terminal of the regulator.

The CMOD and CTANK capacitors are required for CapSense functionality and are provided on the BLE modules (see BLE Module Board on page 106). A 2.2-nF capacitor is present on the CMOD pin, P4[0], for CapSense operation. This kit also supports CapSense designs that enable waterproofing. On this kit, the connection of the shield to the pin or to ground is made by resistors R12 and R13, respectively. By default, R13 is mounted on the board, which connects the shield to ground. Populate R12 and remove R13 when evaluating waterproofing designs, which will connect the shield to the designated pin, P1[6]. Figure 5-12.

A green LED (LED2) indicates the status of the programmer. An amber LED (LED1) indicates the status of power supplied to the board. The kit also has a general-purpose tricolor LED (LED3) for user applications. These are connected to P2_6 (Red LED), P3_6 (Green LED) and P3_7 (Blue LED). Figure 5-14 and Figure 5-15 show the schematics of these LEDs. Figure 5-14.

The reset button is connected to the XRES pin of BLE and is used to reset the BLE device. The user button is connected to P2[7] of the BLE device. Both the push buttons connect to ground on activation (active low). Figure 5-16.

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 bits wide, and the LSB two bits are configurable through physical pins and are hardwired to 00 on the board. By default, the address of the F-RAM device used on the board is 0x50. This address can be modified by changing the R32/R36 and R33/R37 pairs. The operating voltage range of the F-RAM is between 2 V and 3.6 V. To prevent the application of 5 V from the adjustable LDO regulator on the board, a MOSFET based protection circuit similar to the one used for the 3.3-V rail is connected between the output of the regulator and the VDD pin of the F-RAM. The protection circuit cuts off the power to the F-RAM when the output of the regulator is greater than 3.6 V. Figure 5-17.

The pull-ups resistors on I2C bus are enabled when the protocol is selected from user interface (like bridge control panel). The USB-Serial pins of the PSoC 5LP are also available on the Arduino header; therefore, the PSoC 5LP can be used to control Arduino shields with the SPI/I2C/UART interface. Refer Using PSoC 5LP as USB-UART Bridge on page 115 and Using PSoC 5LP as USB-I2C Bridge on page 126 for more information on how to use these serial interconnections Figure 5-18.
