Bluetooth is a short-range wireless technology standard that is used for exchanging data between fixed and mobile devices over short distances and building personal area networks (PANs). In the most widely used mode, transmission power is limited to 2.5 milliwatts, giving it a very short range of up to 10 metres (33 ft).
Bluetooth HID is a lightweight wrapper of the human interface device protocol defined for USB. The use of the HID protocol simplifies host implementation (when supported by host operating systems) by re-use of some of the existing support for USB HID in order to support also Bluetooth HID. Keyboard and keypads must be secure.
It is intended primarily to save cost in low-bandwidth human interface devices (HID) such as keyboards, mice, and joysticks. Full speed (FS) rate of 12 Mbit/s is the basic USB signaling rate defined by USB 1.0. All USB hubs can operate at this rate. High speed (HS) rate of 480 Mbit/s was introduced in 2001 by USB 2.0.
10 Gbit/s (1.212 GB/s, USB 3.1 Gen 2) 20 Gbit/s (2.422 GB/s, USB 3.2 Gen 2x2) A deprecated[2]SuperSpeed USB 5 Gbit/s packaging logo. Universal Serial Bus 3.0(USB 3.0), marketed as SuperSpeed USB, is the third major version of the Universal Serial Bus(USB) standard for interfacing computers and electronic devices. It was released in November 2008.
Headphone and earphone jacks on a wide range of equipment. 6.35 mm (1 ⁄ 4 in) plugs are common on home and professional component equipment, while 3.5 mm plugs are nearly universal for portable audio equipment and headphones. 2.5 mm plugs are not as common, but are used on communication equipment such as cordless phones, mobile phones, and ...
Appearance. This is a list of interface bit rates, is a measure of information transfer rates, or digital bandwidth capacity, at which digital interfaces in a computer or network can communicate over various kinds of buses and channels. The distinction can be arbitrary between a computer bus, often closer in space, and larger telecommunications ...
Bluetooth 2.1 improved device pairing speed and security. Bluetooth 3.0 again improved transfer speed up to 24 Mbit/s. In 2010 Bluetooth 4.0 (Low Energy) was released with its main focus being reduced power consumption. Before Bluetooth 4.0 the majority of connections using Bluetooth were two way, both devices listen and talk to each other.
lwBT is an open source lightweight Bluetooth protocol stack for embedded systems by blue-machines. It acts as a network interface for the lwIP protocol stack. It supports some Bluetooth protocols and layers, such as the H4 and BCSP UART layers. Supported higher layers include: HCI, L2CAP, SDP, BNEP, RFCOMM and PPP .
