Basic BLE Profiles Project
Table of Contents
Introduction
The Basic BLE Profiles project is based on the Basic BLE example and implements a simple Bluetooth low-energy peripheral device with GATT profiles.
This project can be a framework for developing many different peripheral-role applications.
Hardware Prerequisites
The default Basic BLE Profiles board configuration uses the
device's LaunchPad development kit.
Software Prerequisites
For information on what versions of Code Composer Studio and IAR Embedded Workbench to use, see the Release Notes file provided in the SDK. In addition, please refer to the User's Guide for information on importing this project into your IDE workspace and build/run.
GATT Profiles
The GATT profiles can be configured using The "Profiles Configuration" option in SysConfig located within the BLE stack module.
Device Info
The Device Info Service is based on version 1.1 of BT SIG, exposes manufacturer and/or vendor information about a device.

Continuous Glucose Monitoring
The Continuous Glucose Monitoring (CGM) profile, based on version 1.0.2 of BT SIG. It connects to a Central device and generates dummy glucose measurement values.

Usage
To interact with the application over Bluetooth, you may use any device that can act as a BLE Central device, such as
iOS with the apps SimpleLink Connect or other BLE application
Android with the apps SimpleLink Connect or other BLE application
A CC26xx/CC13xx/CC23xx LaunchPad running the sample app HostTest from a compatible SDK with the PC tool BTool from the same SDK.
UART
This application uses the UART peripheral to provide an interface for the application. The UART is only used for display messages.
We recommend using a terminal program that can parse ANSI/VT100 color codes, such as Tera Term, PuTTY, Code Composer Studio Terminal, etc., to monitor the LaunchPad UART output.
The following default parameters are used for the UART peripheral for display:
| UART Param | Default Values |
|---|---|
| Baud Rate | 115200 |
| Data length | 8 bits |
| Parity | None |
| Stop bits | 1 bit |
| Flow Control | None |
