This project would give you a general idea about how to setup and interface any Bluetooth modem with your computer. There are many types of Bluetooth modems available in market, which vary in quality, cost, range, etc. Some of the well known Serial Bluetooth modems are AUBTM, BLUESMIRF, RN-41, HC-05 and HC-04.I would be using the last one i.e. the cheap Chinese Bluetooth module. It has limited functions and it can only work in slave mode. (Remember: Two slave modules cannot directly communicate to each other so be careful when you buy them.) The top range modules have a facility to work in both MASTER and SLAVE modes. It is Class 3 module so it range is very low. (Class 2 has a range of 10 meters and Class 1 has a range of 100 meters.)
Difference between Bluetooth and Zigbee Technologies
Bluetooth protocol is not much encouraged for long duration applications due to power consumption limitations. Hence, for small gadgets which run on battery or limited power source, a new wireless data transfer protocol was needed which could manage working with low power consumption. To fulfill these requirements, a protocol named Zigbee was announced just at…
Difference between Bluetooth and WiFi
Communication is going wireless with the upsurge of smart mobile devices such as laptops, cellular phones, PDA, tablets etc. In order escape traps of wires and to stream data wirelessly among these devices, a number of protocols have been formulated such Bluetooth, Wi-Fi, NFC etc. Using these technologies users can exchange almost all sorts of…
Bluetooth Technology : An overview
Bluetooth is a wireless technology used to transfer data between different electronic devices. The distance of data transmission is small in comparison to other modes of wireless communication. This technology permits hands free headset for incoming voice calls, ability of printing and fax, and automatic synchronization of PDA. A Bluetooth device is comprise of an adapter. A Bluetooth adapter can be available in the form of a card to connect the device or integrated into an electronic device. Link Management Protocol (LMP) is responsible for peer – to – peer message exchange when the electronic devices interfere in each other’s radio range.
Bluetooth Controlled Portable LED Display
The aim of the project is to make a portable LED display from SMD LEDs and to display the custom programmed patterns at our command. The core application of the project is to act as a portable display for event organisers or exhibitionists or consultants to make announcements at their mobile facilities. This can also be used as a novelty item in a showcase.This project is demonstrated by giving an overview of what are the peripherals or hardware used and how it is initialised and used.
Arduino Tutorial: Blink an LED using Bluetooth
Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz) from fixed and mobile devices, and building personal area networks (PANs). Invented by telecom vendor Ericsson in 1994, it was originally conceived as a wireless alternative to RS-232 data cables. It can connect several devices, overcoming problems of synchronizationThis project aims to control an LED via Android Phone using Bluetooth Communication through commonly used module HC-05. For controlling we use an Arduino board with an Atmega8 sitting on it.
