Blood Pressure Profile - Getting Started Guide

USER GUIDE

Introduction

The Blood Pressure Profile (BLP) enables a device to connect and interact with a Blood Pressure Sensor

device for use in consumer and professional health care applications.

The Blood Pressure Profile is used to enable a device to obtain blood pressure measurement and other

data from a non-invasive blood pressure sensor that exposes the Blood Pressure Service. For example, a

nurse or doctor could use a non-invasive blood pressure sensor on a patient that sends blood pressure

measurements to a laptop or other hand held device.

This example demonstrates a Blood Pressure sensor application (GATT Server role).

1 Purpose

This getting started guide describes the setup of an Atmel®ATSAMB11 Xplained board and bringing up

an example profile supplied as part of the BluSDK SMART release. The Bluetooth®Blood Pressure Profile

is an example application that is embedded as part of the software release package.

2 Demo Setup

3 Hardware Setup

Connect the ATSAMB11 board to the host PC using a Micro-USB cable.

4 Blood Pressure Measurements

The Blood Pressure Measurement characteristic shall be used to send blood pressure measurements.

Included in the characteristic there is a Flags field (containing units of blood pressure and used to show

presence of optional fields), the Blood Pressure Measurement Compound Value field and, depending

upon the contents of the Flags field, Time Stamp (time of the measurement), Pulse Rate, User ID, and

Measurement Status fields.

The Intermediate Cuff Pressure characteristic may be notified frequently during the course of a

measurement so that a receiving device can effectively update the display on its user interface during the

measurement process.

When the Client Characteristic Configuration descriptor is configured for indications and a blood pressure

measurement is available, this characteristic shall be indicated while in a connection.

The Blood Pressure Measurement Application, which is the GATT server, will hold the characteristics and

will send the measurement values to the Blood Pressure Monitor.

The Blood Pressure Measurement characteristic shall be used to send blood pressure

measurements

The Intermediate Cuff Pressure characteristic, which is used to send Current Cuff Pressure values

to a device for display purposes while the measurement is in progress

The Blood Pressure Feature characteristic shall be used to describe the supported features of the

Blood Pressure Sensor

ATSAMB11 simulates a Blood Pressure Sensor (GATT Server Role) and sends simulated values to the

Blood Pressure Monitor (SmartConnect mobile application).

5 Software Setup

5.1 Installation Steps

1. Install the latest Atmel Studio [Atmel Studio 7.0 (build 629 or later) web installer

(recommended)]

http://www.atmel.com/tools/ATMELSTUDIO.aspx.

2. Install the latest Atmel Software Framework.

This package will install the following examples within the Atmel Studio environment:

Blood Pressure application for ATSAMB11

5.2 Build Procedure

The following procedure is explained for ATSAMB11 application example.

1. Select New Example Project.

Figure 5-1. Creating a New Example Project

2. Select “SAMB11” in device family, enter “Blood Pressure” in search window, and expand Atmel

Corp Projects. The location and the name of the project can be selected in the respective fields.

Click OK.

Figure 5-2. Selecting Blood Pressure Application from Example Projects

3. Accept the license Agreement. The Atmel studio will generate the Blood Pressure Profile project for

ATSAMB11.

4. Build the solution.

Figure 5-3. Building the Blood Pressure Application

5. Download the application via the USB to the ATSAMB11 board by using the Device Programing

option available in Tools as shown below.

Figure 5-4. Programming the Blood Pressure Application

6. Inside the device programming the user has to select the correct configuration for the device and

finally program the device by using the program button.

Figure 5-5. Flash the Blood Pressure Application

7. Once the application is flashed, the Blood Pressure application is ready for usage.

6 Console Logging

For the purpose of debugging, a logging interface had been implemented in the Blood Pressure

Application.

The logging interface utilizes the same EDBG port that connects to ATSAMB11. A serial port monitor

application (for example TeraTerm) shall be opened and attached to the corresponding COM port

enumerated on the PC by the device. Baud rate should be set at 115200.

7 Running the Demo

1. Power on the ATSAMB11 by connecting the USB cable.

2. Open a console window using TeraTerm or any equivalent serial port monitor application and

connect to the corresponding COM port enumerated on the PC. Configure the COM Port with the

following settings: Baudrate 115200, Parity None, one Stop bit, one Start bit, no Hardware

Handshake.

3. Press the Reset button on the ATSAMB11 board.

4. The device is now in advertising mode.
