INTRODUCTION

• Vehicle to vehicle and Infrastructure communication systems are an

emerging type of networks in which vehicles providing each other

with information, such as safety warnings and traffic information

using Bluetooth and Arduino.

ARDUINO

An open-source physical computing platform based on a

• simple microcontroller board

• A development environment for writing software for the board.

• Tiny computer you can program Completely stand-alone, talks to other devices

•You can connect both digital and analog electronic signals Sensors (GPS

Locators ,Bluetooth ,etc) and Actuators (LEDS or electrical motors)

•Arduino programming can be done in C/C++.

•Arduino IDE has many built–in libraries, functions like LCD,RTC and for

various sensors which can be used for programming

ME-ERTS 8

Why Arduino?

• Inexpensive

• Cross-platform, Simple and clear programming environment

• Open source and extensible software and hardware

BLUETOOTH

• Bluetooth is a wireless LAN technology designed to connect devices of different functions such as telephones, notebooks, computers (desktop and laptop) etc

• Bluetooth project was started by SIG (Special Interest Group) formed by four companies  IBM, Intel, Nokia and Toshiba for interconnecting computing and communicating devices using short-range, lower-power, inexpensive wireless radios.

Bluetooth Timeline

ME-ERTS 16

Bluetooth low energy• It has a data rate of 1Mbps, but is not optimized for file transfer.• It is designed for sending small chunks of data (exposing state)• Three channels, which are located exactly between the Wireless

LAN channels, are used for device discovery and connection setup. • These channels (also known as “advertising” channels) are used by

the technology to search for other devices or promote its own presence to devices that might be looking to make a connection.• In comparison, Classic Bluetooth technology uses 32 channels for

the same task. • BLE has to switch “on” for just 0.6 to 1.2 ms to scan for other

devices using its three advertising channels. Classic Bluetooth, instead, requires 22.5 ms to scan its 32 channels. The power savings are significant: BLE consumes 10 to 20 times less power than Classic Bluetooth technology to locate other radios.

Link Layer Connection• Very low latency connection• A Central device goes through the Link Layer states

Scanner -> Initiator -> Master• A Peripheral device goes through the Link Layer states

Advertiser -> Slave

BLUETOOTH MODULE (HM-10)

• HM-10 BLE-CC41-A is a next-generation, class 2, Bluetooth 4.0 module.

• It support the AT commands.• The user can according to need to change the baud rate of serial

port, name of equipment, matching parameters such as password according to their need.

• HM-10 is a Bluetooth Low Energy (BLE) module built on Texas Instruments CC2540 or CC2541

• The HM-10 module can be configured over the serial connection (pins RXD and TXD) using AT commands

ME-ERTS 23

Cntd…

• CC2541 Bluetooth Chip Solution• BT Version: Bluetooth

Specification V4.0 BLE• Send and receive no bytes limit.• With firmware pre-loaded,

support IOS and Android 4.3• RF Power: -23dbm, -6dbm,

0dbm, 6dbm, can modify through AT Command AT+POWE.

• Security: Authentication and encryption

• Power: +3.3VDC 50mA• Long range: Open space have 100

Meters

ME-ERTS 24

AT Commands

• AT- It just answers back OK and informs that the module is active and waiting for new commands

• AT+ADDR?- It returns the MAC address of the HM-10 module • AT+VERR? -It returns the current firmware version • AT+RENEW- It resets the module to the original factory settings • AT+RESET- It resets/restarts the module • AT+MODEx- It changes the way the module processes AT

commands: • AT+NAMExxxxxxxxx -It changes the name of the module
