Safety Information

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.

The CY8CKIT-042-BLE Bluetooth Low Energy (BLE) Pioneer Kit is intended for use as a development platform for hardware or software in a laboratory environment. The board is an open system design, which does not include a shielded enclosure. For 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 requir ed to take adequate preventive measures. Also, this board should not be used near any medical equipment or 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.

Battery Care and Use

■ Use the correct size and type of battery specified in this guide.

■ Keep battery contact surfaces and battery compartment contacts clean by rubbing them with a

■ Remove the battery from a device when it is not expected to be in use for several months.

■ Make sure that you insert the battery into your device properly, with the + (plus) and – (minus)

■ Do not place the battery next to metallic objects such as keys and coins.

■ Never throw the battery into fire.

■ Do not open up the battery.

terminals aligned correctly.

Battery Disposal

Batteries can be safely disposed of with normal household waste. Never dispose of batteries in fire because they can explode.

It is important not to dispose of large amounts of batteries in a group. Used batteries are often not completely “dead.” Grouping used batteries together can bring these “live” batteries into contact with one another, creating safety risks.

The BLE Pioneer board acts as the baseboard for the PSoC 4 BLE (red module) and PRoC BLE (black module), which can be connected to the BLE Pioneer board. The Pioneer board contains a

CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. ** 23

PSoC 5LP that is used as an onboard programmer or debugger, and for the USB-Serial interface. The Baseboard is Arduino form factor compatible, enabling Arduino shields to be connected on top

of the board to extend the functionality of BLE modules. The board also features a 1-Mb F-RAM, an RGB LED, a five-segment CapSense slider, a proximity header, a user switch, and a reset switch for the PSoC 4 BLE and PRoC BLE devices on the module. The Pioneer board supports three voltage levels: 1.9 V, 3.3 V, and 5 V.

The baseboard can also be used as a standalone programmer to program and debug other PSoC 4 BLE/PRoC BLE devices using serial wire debug (SWD), and as a USB-Serial bridge. The firmware on PSoC 5LP device enables bootloading over USB to upgrade the firmware.

Figure 3-2. BLE Module Block Diagram

This kit includes two modules boards. These boards act as a basic breakout board for the CY8C4247LQI-BL483 and CYBL10563-56LQXI BLE silicon. The PSoC 4 BLE and PRoC BLE Modules are identical except for the silicon. In addition to including the PSoC 4 BLE and PRoC BLE devices, the module boards also contain the BLE passives (resistors, capacitors, external crystals, and antenna-matching network), an onboard antenn a, and headers for conn ecting to the Baseboard.

The Dongle is the host's wireless interface for the BLE device or project on the baseboard. The dongle has a PRoC BLE device, configurable over various interfaces to work as expected for any project. It also contains a PSoC 5LP, to be used as an onboard pr ogrammer or de bugger, and for the USB-Serial interface, as shown in Figure 3-3.

The Dongle has a USB A-type plug to connect the PSoC 5LP to the USB port of the host PC. The PSoC 5LP then communicates with the PRoC BLE device over UART or multiplexed I

C or an SPI bus. The board also features a user LED, a user switch, and a reset switch for the PRoC BLE device. The Dongle is powered directly through the USB port (VBUS) at 5.0 V.

The Dongle can also be used as a standalone programmer to program and debug other PSoC devices (outside the dongle board) using SWD, and as a USB-Serial bridge after removing the resistor between the SWD pins of PSoC 5LP and PRoC BLE.

3.8 Updating the Onboard Programmer Firmware

The BLE Pioneer kit and Dongle contains the modified KitProg that is required to reliably use the BLE Pioneer kit's functionality. Do not update the KitProg firmware on PSoC 5LP on this kit. If the KitProg has been updated with the firmware provided with PSoC Programmer, then you can restore the original KitProg for this kit using the Bootloader Host tool. The required CYACD file is present in the installed location of the ki t:

<Install_Directory>\CY8CKIT-042-BLE Kit\<version>\Firmware\Programmer\KitProg \KitProg.cyacd

Follow the steps in the Advanced Topics chapter on page 113 to restore the KitProg using the Boot- loader Host tool.

3.9 Measure Coin-cell Power Consumption

To measure the power consump tion of a project with coin-cell bat tery, connect the coin-cell battery directly to the BLE Modules as shown in the Figure 3-17. The baseboard is designed with additional circuits to protect the PSoC 4 BLE/PRoC BLE device and the F-RAM in Arduino environment. Note that the power consumption measurements on the baseboard will also include the power consumed by these additional circuits.

After you have programmed your application on the CY8CKIT-142 PSoC CY5671 PRoC™ BLE Module, remove the BLE Module from the baseboard and connect the coincell battery (Figure 3-17). This setup enables an accurate power consumption measurement for the application. The other pins on the BLE Module can be used to build the desired application.

4. Example Projects

This chapter demonstrates the functionality of the PSoC 4 BLE and PRoC BLE devices using the BLE Pioneer kit-based example projects. To access these example projects, download and install the kit setup file from the kit web page. The example projects are available in the firmware folder in the installation location.

The Cypress BLE device comes in two variants:

■ PSoC 4 BLE: The PSoC 4 BLE product family is the new wireless member of the PSoC 4

architecture platform. The family provides a full programmable analog and digital system and a complete schematic view of PSoC Creator. The PSoC 4 BLE family provides a 32-bit ARM Cortex-M0 based MCU subsystem with programmable analog and digital peripherals, such as universal digital blocks (UDBs), 12-bit SAR ADC, Op-amp, LP comparator, IDACs, UART, I SPI, and timer/counter/PWM block. It also has a dedicated CapSense block (in select part numbers) to implement the touch-sensing solution, with a practical system SNR of 100:1.

■ PRoC BLE: This family provides prebuilt part numbers for applications such as human interface

devices (HID), remote control, trackpad, and toys. PRoC BLE also supports up to two-finger gestures for trackpad and remote control applications. The PRoC BLE product family enriches PRoC wireless capacitive touch devices with the Bluetooth Low Energy protocol. The PRoC BLE family has embedded gestures (in select part numbers) to implement the touch-sensing solution for trackpad implementation. It also provides a 32-bit ARM Cortex-M0 based MCU subsystem with analog and digital peripherals, such as 12-bit SAR ADC, UART, I counter/PWM blocks. The family uses a special PSoC Creator schematic view for easy configuration of PRoC BLE devices.

C, PWMs, and timer/

The example projects that are part of this kit installer include projects for both these devices. Unless otherwise indicated, the functionality of the example projects is the same for PSoC 4 BLE and PRoC BLE. The mode of use and the PSoC Creator schematic view will vary slightly for each device.

Note: As stated previously, the BLE Pioneer Kit supports both Cypress BLE devices: PSoC 4 BLE

and PRoC BLE. Thus, there are two v ersions of eac h 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 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 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 BLEenabled sensors, proximity beacons, and so on.

4.2 Kit Test

4.2.1 Project Description

This example project is a non-BLE project that is meant to validate the BLE Pioneer Kit, if desired. This example project verifies whether the onboard device is working properly. It uses one timer that periodically generates an interrupt and causes toggling of the onboa rd LED (Figure 4-7).

Two projects demonstrate this functionality on two different devices:

■ PSoC_4_BLE_Kit_Test works with the PSoC 4 BLE Module.

■ PRoC_BLE_Kit_Test works with PRoC BLE Module.

4.3 CapSense Slider and LED

4.3.1 Project Description

This example project demonstrates bidirectional dat a transfer between a BLE central device ( Dongle or CySmart App) and the kit working as a peripheral with the CapSense slider and RGB LED functionalities. The example project allows advertisement, connection, and data transfer over a custom BLE profile. It uses a CapSense component to read finger location on the CapSense slider and sends the value to a connected BLE central device. The project receives RGB color and intensity values from the BLE central device, which are then translated into the proper color and intensity on the onboard RGB LED.

The project also supports placing the system into sleep in the event of advertising timeout or BLE disconnection. The system then wakes up and resumes when the user button ( pressed.

This is the default firmware that comes in 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 component whereas the PRoC BLE uses the software implement ation of the PRiSM mode.

4.5 BLE Central Mode

4.5.1 Project Description

The BLE projects described above have been functioning as BLE peripheral devices. This means that the firmware role was set to be as a server; an other devi ce, acting as BLE cen tral (such as the CySmart PC tool or CySmart mobile application) will connect to it and collect the data.

This example project demonstrates the BLE client mode where it will scan for peripheral devices and connect to a particular device supporting Immediate Alert Service (IAS). Connection is initiated when the advertising peripheral Bluetooth address matches the pre-determined Bluetooth address that is saved inside the central device firmware. When connected, it sends immediate alert levels with a press of the button ( example project is provided for the Dongle. The BLE IAS peripheral example project is present in the same workspace of the PSoC Creator central IAS example pr oje ct workspace.

The BLE Pioneer kit scans for button presses and sends all three alert levels in circular fashion. The Dongle acting as an IAS peripheral changes the LED behavior according to the received alert level. Upon each successive button press, the LED state changes in a circular fashion. The default level is

No Alert.

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. This

project is present in both PSoC_4_BLE_Central_IAS and 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 BLE

2. Program the Dongle with the BLE_Dongle_Peripheral_IAS project described in Using Example

Projects on page 37.

Note: Do not update the public device address (inside the BLE component) for the BLE_Dongle_Peripheral_IAS example project. This is because the central example project

looks for a particular public address equal to the one set on the peripheral BLE component. Changing the

BLE_Dongle_Peripheral_IAS example project public address will lead to no

connection with the central device on the BLE Pioneer kit.

3. Power the BLE Pioneer kit through USB connector J13.

4. Program the BLE Pioneer kit with either PSoC_4_BLE_Central_IAS or PRoC_BLE_Central_IAS project, depending on the BLE Module placed on the BLE Pioneer kit.

5. Wait for the BLE connection between the dongle and the Pioneer baseboard. The connection success status is indicated on the Baseboard in the following three stages:

a. Fast blinking blue LED represents scanning mode. Du ring this mode, the BLE Pioneer kit is

scanning for peripheral devices.

b. Slow blinking blue LED represents discovery mode. Duri ng this mode, the BLE Pione er kit has

found the Dongle peripheral device and ha s started th e connection procedure.

c. The blue LED remains on, representing the connected mode. This mode means that the

peripheral device has been connected and the application can now send alert levels.

6. Press the user button (

4.6 BLE Dongle and LED Control

4.6.1 Project Description

This firmware supports the CySmart debug tool (see CySmart PC Tool on page 158) by acting as the BLE host emulator . This is the defa ult firmware that comes in Dongle shipped with the kit.

This project additionally demonstrates LED brightness control via a custo m BLE p rofile, wh ich works with the CapSense slider example explained in CapSense Slider and LED on page 46.

The device will scan for the peripheral acting as a CapSense Slider and LED device, and connect to it automatically. 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 proj ect 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 113.

Note: This project is meant only for the PRoC BLE device and works on the Dongle hardware.

5. Hardware

This chapter describes the contents of the BLE Pionee r Kit hardware and it s dif ferent blocks, su ch 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 o f 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. Analog capability spans the range from thermocouples (near DC voltages) to ultrasonic signals.

For more information, visit the PSoC 5LP web page. See the section Serial Interconnection Between PSo C 5LP and Bluetooth Module on page 100 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:

■ 5-V power from onboard USB connector

■ 5-V to 12-V VIN power from Arduino shield

■ 3.3 V from I/O header

■ 3 V from CR2032 coin cell

CY8CKIT-042-BLE Bluetooth® Low Energy (BLE) Pioneer Kit Guide, Doc. # 001-93731 Rev. ** 83

Hardware

An adjustable LDO is used to output three dif ferent volt age levels (1.9 V, 3.3 V, and 5 V) to power the BLE Module. These voltages are selected through the J16 jumper, as shown in Figure 5-1.

Figure 5-1. Schematics and Board Highlight of LDO and Power Selection Jumper

The input to the LDO can come from either the USB or the VIN pin in the Arduino header.

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.

5.1.9 Cypress Ferroelectric RAM (F-RAM)

The baseboard contains an F-RAM device (FM24V10) (see Figure 5-18) that can be accessed through I (128 KB) with an I

wide, and the LSB two bits are configurable through physical pins and are hardwired to 000 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 r ange of th e 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.
