Getting Started With EZ-BLE™ PRoC™ Module
Introduction
Bluetooth Low Energy (BLE) is an ultra-low-power
wireless standard defined by the Bluetooth Special
Interest Group (SIG) for low-power, short-range
communication. It features a physical layer, protocol stack,
and profile architecture, all designed and optimized for the
lowest power consumption. BLE operates in the 2.4-GHz
ISM band, with a data rate of 1 Mbps.
BLE is used in a wide range of applications. The use of
BLE in these applications also varies widely in production
volume, from very low- to high-volume end products. As
such, fully qualified, certified, BLE modules have fast
become the design preference. The use of modules
removes time consuming and costly
qualification/certification processes.
The Cypress EZ-BLE PRoC Module is a fully integrated,
qualified and certified, programmable system that
integrates 32-kHz and 24-MHz crystal oscillators, passive
components, on-board chip antenna, and Cypress‘s
PRoC™ BLE chip (BLE radio, programmable analog and
digital peripherals, memory, and an ARM® Cortex®-M0
microcontroller) on a small 10 mm × 10 mm × 1.8 mm
module.
The EZ-BLE PRoC Module enables a quick time-to-market
and eliminates costly certification and qualification
processes, offering an effective alternative to completing a
BLE system design from ground up. In addition to
reducing the cycle time, certification and qualification
expenses, the programmable peripherals and GPIOs allow
great flexibility using PSoC Creator IDE, the schematicbased design tool for designing applications with EZ-BLE
PRoC Module, and a speedy time to market.
The BLE stack library is integrated with PSoC Creator and
is free-of-cost. It can be easily configured using a simple
graphical user interface, allowing you to jumpstart your
BLE design in minutes.
The EZ-BLE PRoC Module offers a best-in-class current
consumption of 150 nA while retaining the SRAM contents
and the ability to wake up from an interrupt. The EZ-BLE
PRoC Module consumes only 60 nA while maintaining the
wakeup capability in its nonretention power mode. The
capacitive touch-sensing feature in the EZ-BLE Module,
known as CapSense®, offers an unprecedented signal-tonoise ratio, best-in-class waterproofing, and a wide variety
of sensor types such as buttons, sliders, and proximity
sensors that are gaining increased popularity in wearable
electronic devices such as activity monitors, health, and
fitness equipment.

Low Power Modes
EZ-BLE PRoC Module supports the following five power modes as illustrated in Figure 4:
Active mode: This is the primary mode of operation. In this mode, all peripherals are available.
Sleep mode: In this mode, the CPU is in sleep mode, SRAM is in retention, and all the peripherals are available. Any
interrupt wakes up the CPU and returns the system to Active mode.
Deep-Sleep mode: In this mode, the high-frequency clock (IMO) and all high-speed peripherals are off. The WDT, LCD,
I2C/SPI, link layer, and low-frequency clock (32-kHz ILO) are available. Interrupts from GPIO, WDT, or SCBs can cause a
wakeup. The current consumption in this mode is 1.3 µA for all PRoC BLE devices in the family.
Hibernate mode: This power mode provides a best-in-class current consumption of 150 nA while retaining SRAM,
programmable logic, and the ability to wake up from an interrupt generated by a GPIO.
Stop mode: This power mode retains the GPIO states. Wakeup is possible by using the external reset (XRES) pin on the
module. The current consumption in this mode is only 60 nA.

Bluetooth Low Energy Overview
The Bluetooth SIG defines Bluetooth 4.1, also known as Bluetooth Smart or Bluetooth Low Energy as the lowest-power
wireless standard operating in the 2.4-GHz ISM band. Figure 6 summarizes the BLE protocol stack architecture.
The following sections briefly describe the BLE stack layers. For a detailed architecture description, see the Bluetooth 4.1
specification or the training videos on the Bluetooth Developer website. If you are familiar with the Bluetooth BLE stack, you
can skip these sections. Figure 10 shows the system design for a heart rate monitoring application.
Figure 6. BLE Architecture
Physical Layer (PHY)
The physical layer transmits or receives the digital data at
1 Mbps using GFSK modulation in the 2.4-GHz ISM band.
The BLE physical layer divides the ISM band into 40 RF
channels with a channel spacing of 2 MHz, 37 of which
are data channels and 3 are advertisement channels.
Link Layer (LL)
The link layer implements various key functionalities that
make the BLE protocol robust and low-power. Some of
these are the following:
Adaptive Frequency Hopping (AFH) to provide RF
interference immunity
24-bit CRC and AES-128-bit encryption for robust and
secure data exchange
Advertising, scanning, creating and maintaining
connections to establish a physical link
Establishing fast connections and low duty cycle
advertising for low-power operation
Host Control Interface (HCI)
HCI is the interface between the host and the controller.
This layer allows the host and the controller to exchange
information such as command, data, and events over
different transports.
Logical Link Control and Adaptation
Protocol (L2CAP)
L2CAP provides protocol multiplexing, segmentation, and
reassembly services to upper-layer protocols.
Segmentation and reassembly breaks the packet received
from the upper layer into smaller packets that the link layer
can transmit, and vice versa. The Bluetooth Low Energy
L2CAP layer supports three protocol channel IDs for ATT,
SM and L2CAP control. Bluetooth 4.1 allows direct data
channels through L2CAP (connection-oriented channels)
on top of these protocol channels.

Security Manager (SM)
The SM layer defines the methods used for key
distribution to perform encryption and pairing.
Pairing is the process to enable security features. In
this process, two devices are authenticated, the link is
encrypted, and then keys are exchanged.
Bonding is the process in which the keys and identity
information exchanged during the pairing process are
saved within the paired devices. Bonded devices do
not have to go through the pairing process again
when reconnected.
Attribute Protocol (ATT)
ATT forms the basis of the BLE communication. This
protocol enables the client to find and access attributes on
the server. An attribute is the fundamental data-carrying
element in BLE, which consists of the following:
Attribute Handle: This is the 16-bit address assigned
by the attribute server to allow its client to identify and
access an attribute.
Attribute Type: This specifies the type of data stored
in an attribute. It is represented by a 128-bit number
called a universally unique identifier (UUID).
Bluetooth SIG defines the Bluetooth Base UUID,
which is 128 bits long. In this base UUID, typically 16
bits (32 bits for Bluetooth 4.1) are used to identify an
attribute type.
The Bluetooth Base UUID is:
0x0000xxxx-0000-1000-8000-00805F9B34FB
The 16-bit UUID of the Heart Rate Service (HRS) is
0x180D, so the complete 128-bit UUID for the HRS is
0x0000180D-0000-1000-8000-00805F9B34FB
Attribute Value: This is the actual data stored in the
attribute.
Several types of attributes are defined by Bluetooth SIG;
some of which are as follows:
Service: The service attribute defines the function
performed by the server. It is a collection of data
entities called ―characteristics‖ and can also include
other services.
A service can be of two types: primary service or
secondary service. A primary service exposes the
main functionality of the device while the secondary
service provides additional functionality that a primary
service encapsulates, but that is not required to be
exposed. In a heart rate monitoring device example,
HRS is a primary service and Battery Service (BAS) is
a secondary service.
Characteristic: The characteristic attribute exposes
the data, and consists of an attribute that holds the
value and a descriptor. ―Battery level‖ is an example
of a characteristic.
Descriptor: The descriptor is a part of the
characteristic declaration, and provides additional
information about the characteristic. Representing the
battery level in percentage values is an example of
characteristic descriptor.
Figure 8 shows the structure of a characteristic.
Figure 8. Characteristic Format and Example
Attribute Permission: This specifies whether an
attribute can be read or written, and the security level
required. Attribute permission is set by the higher
layer specification and is not discoverable through the
attribute protocol.
Figure 7 shows the structure of an attribute with an
example.
Figure 7. Attribute Format and Example
www.cypress.com Document No.: 001-96841 Rev. ** 9
Attribute Operations: These are accessed using the
following five basic methods:
Read Request: Sent by the client to read an
attribute value. For every request, the server
sends a response to the client.
Write Request: Sent by the client to write an
attribute value. The sever responds to the client
confirming whether the value is written.
Write Command: Sent by the client to the server
to write an attribute value. The server does not
send any response for the write command.
Notification: Sent by the server to the client to
notify a new value or a change in value. The client
does not send any response for a notification
command.
Indication: A type of notification from the server
that is always confirmed by the client.

Figure 10 shows the services and characteristics
implemented in the peripheral.
Generic Attribute Profile (GATT)
GATT defines the ways in which the attributes can be
found and used. GATT operates in one of two roles:
GATT client: The device that requests the data.
GATT server: The device that provides the data.
Figure 9 shows the client-server architecture in the GATT
layer.
Figure 9. Client-Server Architectures
Figure 10 shows an example in which a smartphone is
configured as the GATT client (wants data) and a heart
rate sensor that is configured as the GATT server (has
data).
Generic Access Profile (GAP)
The GAP layer provides the device-specific information:
device address, device name, and how it can be
discovered and connected.
Profile: This specification defines how devices connect to
each other to find and use services. It describes the type
of application and general expected behavior of that
device. Figure 10 shows an example of a Heart rate
monitor Profile.
The GAP layer operates in one of four roles:
Broadcaster: This is a non-connectable advertising
role that is used to broadcast its data, but cannot form
BLE connections. A typical example of a GAP
broadcaster is iBeacon.
Observer: This is a listening role that scans for
advertisements. It is capable of connections but
cannot initiate one. A typical example of a GAP
observer is a packet sniffer.
Peripheral: This is a connectable advertising role that
operates as a slave after a connection is established.
For example, a heart-rate sensor reporting the
measured heart-rate to a remote device operates as a
GAP peripheral.
Central: This is a GAP role that scans for
advertisements and initiates connections. It operates
as a master after a connection is established. For
example, a mobile device retrieving the heart-rate
measurement from a peripheral heart-rate sensor
operates as a GAP central.
Figure 10 shows an example where a smartphone in
which the heart rate app operates as a GAP central and
the heart-rate sensor operates as a GAP peripheral.

Figure 10. Bluetooth Low Energy System Example
In Figure 10, the heart rate monitoring device operates as the GAP peripheral and implements the heart rate sensor profile,
while the smartphone receiving the data operates as the GAP central and implements the heart rate collector profile.
In this example, the heart rate sensor profile implements two standard services the heart rate service that comprises three
characteristics (the Heart Rate Measurement Characteristic, the Body Sensor Location Characteristic, and the Heart Rate
Control Point Characteristic) and the Device Information Service. At the link layer, heart rate measurement device is the slave
and the smartphone is the master

Bluetooth Low Energy Component Software
The Bluetooth Low Energy Component provides a comprehensive GUI-based configuration window that lets you quickly
design applications that require BLE connectivity. The Component incorporates a Bluetooth Core Specification v4.1 compliant
BLE protocol stack and provides API functions to enable user applications to interface with the underlying Bluetooth Low
Energy Sub-System (BLESS) hardware via the stack.
The Component supports the SIG-adopted GATT-based profiles and services as well as custom BLE profiles and services,
and it allows various GAP and GATT roles to be configured. The Component generates the necessary code for a particular
profile and service operation, as configured in the GUI, abstracting the underlying BLE stack and hardware configuration so
that you can concentrate on the system design.
The BLE Component also provides profile Application Programming Interfaces (APIs) to design BLE solutions without
requiring manual stack-level manipulation. The exception to this is the L2CAP configuration specified in Bluetooth v4.1, which
allows advanced users to configure the L2CAP layer of the stack if desired.
Developing Bluetooth Low Energy Application involves four easy steps. For detailed information, refer to AN94020 – Getting

The Bluetooth Low Energy CySmart (Figure 12 ) is a Windows-based tool that provides a host emulation software platform for
testing and debugging LE peripheral or sensor applications. The tool provides an easy-to-use graphical user interface (GUI) to
enable customers to configure, test and debug their solutions. The tool is available as an independent software application and
can be launched from the PSoC Creator IDE as shown in Figure 62.
CySmart, along with a Cypress BLE dongle, acts as a master device. The tool supports the Bluetooth 4.1 specification and
can connect to any Bluetooth 4.1 or 4.0 enabled BLE peripheral devices. Comprehensive test scenarios can be created
by configuring the scan, connection and security parameters. The tool provides the ability to analyze advertisement
data and scan response data, and explore the Generic Attribute Profile (GATT) database of peripheral device. For more
information, refer to CySmart User Guide.

The mobile app supports Bluetooth SIG-adopted BLE standard profiles through an intuitive GUI and abstracts the underlying
BLE and characteristic details.
Development Kits and Evaluation Boards
Cypress provides an easy-to-use development kit to help you prototype your EZ-BLE PRoC Module design.
CY8CKIT-042 BLE Pioneer Kit
The CY8CKIT-042 BLE Pioneer Kit shown in Figure 14 is an Arduino Uno-compliant BLE development kit for the PRoC BLE
family of devices, including the CYBLE-022001-00 module. The CY8CKIT-042 BLE kit consists of pluggable BLE modules that
connect to a baseboard. The Pioneer Kit is powered through the USB interface or with a coin cell battery.
The Pioneer baseboard and RF module combination enables you to develop battery-operated low-power BLE designs that
work in conjunction with standard Arduino shields and additional PSoC 4 BLE device capabilities such as the CapSense user
interface on the Pioneer baseboard.
The kit also contains a BLE USB dongle that acts as a BLE master and works with the CySmart application to provide a BLE
master emulation platform on non BLEWindows systems.
Cypress also provides an adapter board for the EZ-BLE PRoC Module to evaluate and develop with the Cypress module
without the need to develop custom hardware.

CYBLE-022001-EVAL EZ-BLE PRoC Module Evaluation Board
The EZ-BLE PRoC Module Evaluation board (CYBLE-022001-EVAL) is a simple evaluation board designed to fan out the
EZ-BLE PRoC Module (CYBLE-022001-00) connections to headers compatible with the CY8CKIT-042-BLE Pioneer Kit.
The CYBLE-022001-EVAL board is used to evaluate the Cypress EZ-BLE PRoC Module without your having to design custom
hardware to mount the Cypress EZ-BLE PRoC Module.
Figure 15 shows the CYBLE-022001-EVAL connected to the CY8CKIT-042-BLE Kit.

Getting Started With EZ-BLE™ PRoC™ Module
The CYBLE-022001-EVAL board contains the following components:
Cypress EZ-BLE PRoC Module (CYBLE-022001-00) – soldered directly to the Evaluation Board
PCB substrate used for I/O fan out
Connection headers
C
capacitor (for use with Capacitive Sensing elements on the CY8CKIT-042-BLE kit)
mod
Inductors (power supply – see the datasheet specification for recommended external components)
This evaluation board is designed to simulate the placement and connection of the EZ-BLE PRoC Module in a final
application. All host-side layout pattern recommendations (as shown in Figure 5) are followed in the evaluation board.
Note that not all connections available on the CY8CKIT-042-BLE are populated on the CYBLE-022001-00/CYBLE-022001EVAL modules. This is due to the number of I/Os supported on the CYBLE-022001-00 module. When designing applications,
PSoC Creator will only display connections that are available on the CYBLE-022001-00 module and CYBLE-022001-EVAL.
The next page will describe in detail the connections of the CYBLE-022001-EVAL board and the corresponding connections
on the CY8CKIT-042-BLE development kit.
To place the CYBLE-022001-EVAL on the CY8CKIT-042-BLE baseboard, locate the 20-pin (J11) and 24-pin (J10) connection
headers, as shown in Figure 16.
