Getting Started with Bluetooth for Developers Without Basic Knowledge: Points it Requires : 1 Type:CourseUploader:frogluckyDate:2013-09-29; Introduction: Getting Started with Bluetooth Development without Basics 1 Document Introduction 1.1 Document Purpose This document is based on the premise that the software developers have no practical experience in Bluetooth driver development and have a weak understanding of Bluetooth. There are two purposes for writing this document. First, to have an overall understanding of Bluetooth, including the overall situation of Bluetooth, Bluetooth protocol stack and the overall overview of Bluetooth driver development; second, to provide as much technical support as possible in actual development. 1.2 Document Scope This document provides a technical reference for subsequent Bluetooth module driver development. 1.3 Readers Bluetooth group developers. 2 Bluetooth General Introduction 2.1 Bluetooth Introduction Bluetooth is a radio technology that supports short-range communication between devices (generally within 10m). It can exchange wireless information between many devices including mobile phones, PDAs, wireless headphones, laptops, and related peripherals. Using \"Bluetooth\" technology can effectively simplify the communication between mobile communication terminal devices, and can also successfully simplify the communication between devices and the Internet, so that data transmission becomes faster and more efficient, broadening the road for wireless communication. Bluetooth uses a distributed network structure, fast frequency hopping and short packet technology, supports point-to-point and point-to-multipoint communication, and works in the globally common 2.4GHz ISM (i.e. industrial, scientific, and medical) frequency band. Its data rate is 1Mbps. A time-division duplex transmission scheme is used to achieve full-duplex transmission. Bluetooth works in the globally common 2.4GHz ISM (i.e. industrial, scientific, and medical) frequency band. The data rate of Bluetooth is 1Mb/s. A time-division duplex transmission scheme is used to achieve full-duplex transmission. The IEEE802.15 protocol is used. 2.2 Specifications and characteristics of Bluetooth technology The standard of Bluetooth is IEEE802.15, which works in the 2.4GHz frequency band with a bandwidth of 1Mb/s. Full-duplex communication is carried out in a time-division manner, and its baseband protocol is a combination of circuit switching and packet switching. A synchronous packet is sent on a frequency hopping frequency, and each packet occupies a time slot, which can be extended to 5 time slots using spread spectrum technology. At the same time, Bluetooth technology supports 1 asynchronous...

MT8852B fully supports the test of V2.1 (including EDR) Version 3.0 + HS is a new generation of Bluetooth technology standards, which was recently adopted by SIG (May 2009). It mainly allows Bluetooth to transmit at high speed through 802.11a/b/g radio. The main new features include: Enhanced Power Control, HCI Read Encryption Size, Unicast Connectionless data, L2CAP Enhanced Retransmission Mode, L2CAP Steaming Mode ---- Currently only MT8852B can support the above features.

A Brief Discussion on Bluetooth Wireless Testing: Points it Requires : 1 Type:Application DocumentsUploader:justyouandmehrDate:2013-09-29; Introduction: Brief Introduction to Bluetooth Wireless Testing Abstract This article discusses the indicators and test methods of Bluetooth wireless testing, and briefly introduces Anritsu\'s Bluetooth wireless testing solution. Keywords Compatibility test Wireless test RF indicators Bluetooth wireless tester In order to obtain the Bluetooth trademark, Bluetooth product manufacturers must submit their Bluetooth products to BQTF (Bluetooth Certification Test Equipment) for testing, and send their test results and products to BQB (Bluetooth Certification Personnel) for review. Bluetooth certification is relatively complicated. For each Bluetooth certification, the applicant must pay a considerable fee to BQRB (Bluetooth Certification Evaluation Board). Therefore, it is very necessary for Bluetooth product manufacturers to conduct Bluetooth pre-certification. Bluetooth testing includes compatibility testing and interoperability testing. Bluetooth wireless testing belongs to compatibility testing, which verifies whether the RF performance of Bluetooth products meets the Bluetooth RF specifications. Many OEM manufacturers directly purchase Bluetooth chips or modules that have obtained Bluetooth certification, and then develop Bluetooth products such as mobile phones, personal digital assistants (PDAs), computers, printers, MP3 players, digital cameras, cars, toys, etc. Due to the needs of different types of products, the antenna may need to be replaced, or due to the influence of other wireless modules or clock modules, as well as changes in power supply, these will cause the RF performance of the Bluetooth final product to change. Therefore, the RF performance of the product must be tested during the R&D and production process to ensure that its wireless indicators meet the requirements of the Bluetooth RF specification. 1 Bluetooth wireless test methods and indicators The current version of the Bluetooth wireless test specification is version 0.91, which defines Bluetooth wireless test indicators and their test methods. The Bluetooth wireless test configuration includes a tester and a device under test (EUT, Equipment Under Test), in which the tester is the master unit and the EUT is the slave unit. The two can be connected by an RF cable or by an antenna through air transmission. The tester sends an LMP instruction to activate the EUT to enter the test mode and configure some parameters of the Bluetooth link between the tester and the EUT. For example, whether the test mode is loopback or transmission mode, whether frequency hopping is required, whether the grouping is single-slot grouping or multi-slot grouping, and whether the net number of the grouping is PN9, or 00001111, 01010101. Test mode is a special state. For safety reasons, the EUT must first be set to \"En...

Some thoughts after learning Bluetooth: Points it Requires : 1 Type:Application DocumentsUploader:csdn_canDate:2013-09-29; Introduction: Bluetooth is a low-power, short-range wireless transmission technology. Bluetooth originated from the name of the Danish king more than 1,000 years ago, which meant to unify the fragmented form. Ericsson is the founder of Bluetooth technology, which aims to unify the various wireless communication situations and form a unified standard. Later, Nokia, Toshiba, IBM, Intel and other companies joined and established the SIG, a special interest group, and more companies joined later. So far, more than 2,000 companies have joined the organization. There is no doubt that Bluetooth has occupied a pivotal position in short-range wireless communication. First, let\'s introduce the Bluetooth protocol and specification. What is the Bluetooth protocol? What is the Bluetooth specification, and what is the relationship between them? The Bluetooth protocol (protocol) is an industry-wide usage agreement for it. Everyone uses it according to this protocol specification, so as to achieve interoperability of Bluetooth devices produced by various manufacturers. Currently, Bluetooth 2.0 is widely used, and Bluetooth 1.1 has 13 protocols, each of which has a clear purpose. The Bluetooth protocol can be divided into four layers: Core protocol: baseband, L2CAP, LMP, SDP Cable replacement protocol: RFCOMM Telephone transmission control protocol: TCS binary, AT command set, Optional protocol: PPP, UDP/TCP/IP, OBEX, WAP, etc. (the description of the protocol is omitted) Combining several protocols to form a functional combination is called a specification. The specification is composed of a protocol stack or some protocols in the protocol stack. For example, the simple specification FTP includes OBEX, RFCOMM, L2CAP, SDP. The relationship between them is that some or all of the protocols in the protocol stack form specifications according to specific purposes. At present, Bluetooth manufacturers integrate chips and firmware. The firmware contains two parts: the link manager (LM) and the HCI host control interface. The LM controls various functions at the link layer, and the host control interface provides a command interface for calling and accessing the baseband controller and link controller as well as the hardware status and control registers. In other words, it provides a unified method for accessing Bluetooth baseband functions. The firmware will solidify the profile, so if the firmware lacks the corresponding p...
