The eb506 is an add- on component to the z-World rcM3000, Rcm3100 RCM3200, and RCM3300; enabling wireless communications with other Bluetooth devices including cellular phones, handheld computers, PCs, and other serial port adapters Hobbyists, developers, and OEMs can take advantage of advanced wireless connectivity with this easy to use module The eb506 module provides a point to point connection much like a standard serial cable Connections are made dynamically and can be established between two eb506 modules or an eb506 module and a standard bluetooth v1. 1 or v1.2 device. Devices can be dynamically discovered and connected in an ad-hoc manner Below is a list of typographical conventions used in this manual In the command set section of this manual Required parameters and placeholders appear in standard lowercase type Placeholders appear in For example, if shows up in a syntax line the actual address of the device must be entered Required parameter options are separated by a vertical bar I Optional parameters are enclosed in brackets [ Embedded blue 506 User manual TheBluetoothwebsitewww.bluetooth.comcontainstheBluetoothspecificationprofiles and other documents relevant to bluetooth General information regarding the eb506 module, Embedded Blue, and other Bluetooth productsfromA7Engineeringcanbefoundonthea7websiteatwww.a7eng.com TechnicalsupportforEmbeddedblueproductsisavailableviaemailsupporta7eng.com andanonlinediscussionforumwww.a7eng.com/support/forum/forum.htm.It recommended that you make use of the online forum, as many questions may be answered quickly by others, and you may even find the answer to your question already in a post A7 Engineering also provides professional design services on a contract basis to anyone requiring assistance with their design and/or development of bluetooth products For further informationvisittheA7enGineeringwebsitewww.a7eng.com/services/services.htm Embedded blue 506 User manual Bluetooth Overview To put it simply, Bluetooth is a technology standard for electronic devices to communicate with each other using short-range radio. It is often referred to as a cable replacement technology, because it is commonly used to connect things, such as cameras, headsets, and mobile phones that have traditionally been connected by wires. bluetooth is much more than simply a way to cut the cord between today,'s existing electronic devices. It is an enabling technology that will take these devices to new levels of productivity and functionality and enable a whole new class of devices designed with communications and connectivity in mind The Bluetooth Special Interest Group(SIG)defines bluetooth a bit more broadly as the worldwide specification for small-form-factor, low-cost radio solutions that provide links between mobile computers, mobile phones, other portable devices, and connectivity to the Internet. "In defining Bluetooth, the Sig has taken a very different approach than the IEEE 802.11 Committees did. Rather than build Bluetooth as an adjunct to TCP/IP, it was defined as a standalone protocol stack that includes all layers required by an application. This means that it encompasses not only wireless communications but also service advertisement, addressing, routing, and a number of application-level interfaces referred to as profiles Bluetooth is based on a frequency hopping spread spectrum(FHSS)modulation technique The term spread spectrum describes a number of methods for spreading a radio signal over multiple frequencies, either simultaneously (direct sequence)or in series (frequency hopping. )Wi-Fi devices are based on direct sequence spread spectrum transmission which uses multiple channels simultaneously. While this technique increases the speed of transmission (for example in Wi-Fi from 1.5MHz to 1 1MHz), it is more susceptible to interference from other radio sources as well as being a greater source of interference to the surrounding area In contrast, Bluetooth utilizes the frequency hopping method of spread spectrum which uses multiple radio channels to reduce interference and increase security the signal is rapidly switched from channel to channel many times per second in a pseudo-random pattern that is known by both the sender and receiver(s). This provides robust recovery of packet errors caused by interference from another radio source at a particular frequency. Also, data is generally more secure because it is not possible to receive more than a fraction of the data Embedded blue 506 User manual unless the hopping pattern is known. Bluetooth utilizes frequency hopping in the 2. 4GHz radio band and hops at a relatively fast pace with a raw data rate of about 1 Mbps. This translates to about 700 kbps of actual useful data transfer. The eb506 module supports a maximum sustained bidirectional data rate of 230 kbps Bluetooth devices can support interoperability with one or more types of devices. In order for two Bluetooth devices to communicate with each other, they must share at least one common profile. If I want a Pocket Pc to communicate with my Embedded Blue radio I need to make sure that they both support the same profile. Embedded blue devices support the Serial Port Profile(SPP)which is one of the earliest and most widely supported profiles The main elements of the bluetooth Applications stack are shown in the figure to the right As with a typical diagram of the TCP/IP stack. there are a number of details that Bluetooth profile are hidden by the apparent simplicity of SPP(Serial Port Profile the stack. Specifically, there are a number of profiles that sit roughly on top of the L2CAP layer that provide much of DP RFCOMM the power (and also the complexity ) of the Bluetooth protocols These profiles are the primary entry into L2CAP the stack for an application. Essentially they define the set of services that are available to that application. Currentl HCl (Host Controller Interface) there are more than 25 different profiles defined or in the process of being defined by the Bluetooth SIG. With so Link Manager Protocol much variety, acquiring an in-depth understanding of bluetooth is not a trivial task. However, the abstraction by a Baseband and Physical transport single profile can provide an application the use of the profile without such detailed knowledge There are a number of profiles that are exposed in very familiar forms. The eb506 module, for instance, implements the SPP profile which enables it to appear like a traditional serial port This virtually eliminates the need for the user to have specific Bluetooth knowledge and allows the radios to be integrated into applications very quickly Embedded blue 506 User manual
