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).
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 .
99 g. Memory. 5.6 MB. Display. 176×220 pixel TFT LCD. The Motorola RAZR V3, popularly called simply the Razr (pronounced / ˈreɪzər / like "razor"), is a clamshell style cell phone developed by Motorola and initially released in November 2004, the first device using the RAZR moniker. With its unique and then-thin aluminium body, coupled with ...
The StarTAC is a series of mobile phones released by Motorola starting in 1996. It is the successor of the MicroTAC, a semi- clamshell design first launched in 1989. [2] Whereas the MicroTAC's flip folded down from below the keypad, the StarTAC folded up from above the display. The StarTAC was among the first mobile phones to gain widespread ...
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.
The original Java Specification Request (JSR-82) was submitted by Motorola and Sun Microsystems, and approved by the Executive Committee for J2ME in September 2000. JSR-82 provided the first standardized Java API for Bluetooth protocols, allowing developers to write applications using Bluetooth that work on all devices conforming to the specification.
The Bluetooth protocol RFCOMM is a simple set of transport protocols, made on top of the L2CAP protocol, providing emulated RS-232 serial ports (up to sixty simultaneous connections to a Bluetooth device at a time). The protocol is based on the ETSI standard TS 07.10. RFCOMM is sometimes called serial port emulation.
