Bluetooth wireless technology

Server A device that receives GATT commands and requests, and returns responses, for example, a temperature sensor. Short-range transmission of health sensor data from medical devices to mobile phone, set-top box or dedicated telehealth devices.

bluetooth wireless technology

Bluetooth is commonly used to transfer sound data with telephones i. The discovery latency is therefore determined by a probabilistic process and depends on the three parameters viz.

Celsiusand the maximum and minimum values which the sensor can measure. The basic hopping pattern is a pseudorandom ordering of the 79 frequencies in the ISM band. More technical details may be obtained from official specification as published by the Bluetooth SIG.

Advertising and discovery[ edit ] BLE devices are detected through a procedure based on broadcasting advertising packets. The server can then send Bluetooth wireless technology value to the client whenever it becomes available.

How Bluetooth Works

For controls where infrared was often used. The core system employs a frequency-hopping transceiver to combat interference and fading. A given device may also be part of one or more piconets, either as a master or as a slave.

How does Bluetooth work?

Bluetooth devices are managed using an RF topology known as a "star topology. All of the other devices in your piconet are known as slaves. For example, the Device Information service has the short code 0xA, rather than A Wireless streaming of data collected by Bluetooth-enabled fitness devices to phone or PC.

If the connection is broken the marker is out of range of the phone then an alarm is raised. This is done using 3 separate channels frequenciesin order to reduce interference.

Frequency hopping takes place between the transmission or reception of packets, so the packets that make up one transmission may be sent over different frequencies within the ISM band. The client may request a notification for a particular characteristic from the server.

While some desktop computers and most recent laptops come with a built-in Bluetooth radio, others require an external adapter, typically in the form of a small USB " dongle.

Bluetooth technology uses the principles of device "inquiry" and "inquiry scan. When an inquiry is received, the scanning device sends a response with the information needed for the inquiring device to determine and display the nature of the device that has recognized its signal.

FreeBSD features Bluetooth since its v5. For instance, a temperature sensor server may notify its client every time it takes a measurement.Bluetooth is a radio communication technology that enables low-power, short distance wireless networking between phones, computers, and other network devices.

The name Bluetooth is borrowed from King Harald Gormsson of Denmark who lived more than. Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG) aimed at novel applications in the healthcare, fitness, beacons, security, and home entertainment industries.
