What Can I Do With Bluetooth Wireless Technology?
    Bluetooth wireless technology makes the sharing and exchange of information between mobile or static devices as simple as possible. Whether at home, on the move, or in the office it can be used for networking, sharing files, synchronizing information, email, Internet access, printing, and more. In industry it can be used to wirelessly control equipment and machinery - perfect for servicing inaccessible devices.

What's the difference between LBDK and EBDK?

A. LBDK is Chinese version, while EBDK is in English.
B. LBDK supports bidirectional transmission, while EBDK only
supports unilateral transmission.
C. The dimension of LBDK is no more than a quarter of EBDK.
D. LBDK supports dynamic configuration while EBDK supports one-off.
E. Its price is much lower than that of EBDK.

How does LBDK help you with your R&D?

The forepart user of bluetooth technology can help to extend itsapplication, shorten development period and cut expense. LBDKprovides a flexible design environment. It demonstrates the key features of bluetooth technology and offers all the bluetoothfunctions required. It consists a mother board and a sub-boardwhich is convenient to upgrade. LBDK is a ideal tool fordevelopment based on host, supplying the basic bluetooth software including API interface.

When will the BLUETOOTH GATEWAY be published?

And its functions? Lanlingtong "LLTR" will come out at the late of the Jan. ,2002. Following is the functions.

LLTR provides various interfaces. It enables a connection between bluetooth terminal and wired network (Internet/Intranet). Thus bluetooth terminals realize their connectivity to the internet withoutcords. Remote surveillance, control and information share of bluetooth terminals sustaining PAN physically will be achieved.

What's the difference between our BLUETOOTH GATEWAY and others'?

JINOU BLUETOOTH GATEWAY supports 7 bluetooth equipments toaccess Broad Band, complying with TCP/IP, HTTP, FTP, ARP, Telnetand PPP, etc. It also provides audio communication and IP voice communication to PSTN. No matter whether bluetooth terminals (such as bluetooth mobile) can realize LAN ACCESS PROFILE or
support TCP/IP, BLUETOOTH GATEWAY can link them to PCs in the LAN or the Internet and other bluetooth terminals on the other side of BLUETOOTH GATEWAY. So PCs without bluetooth function also can communicate with bluetooth equipment. Thus makes remote control come true.

What's the functions of EXTERNAL BLUETOOTH MODULE?

In brief, EXTERNAL BLUETOOTH MODULE makes equipment without bluetooth function realize the whole bluetooth functions.

How to use EXTERNAL BLUETOOTH MODULE?

User sends instruction to the module to search bluetooth equipments and establish links, then transmit ACL data, finally undo the links. And to judge whether it succeeded by instruction fed back. the following is the steps:
(1) Send demand instruction
(2) Find bluetooth equipment address. (If user knows the address, he can establish link directly.)
(3) Send connection instruction according to the bluetooth equipment address.
(4) If succeed, send data by prescriptive format.
(5) After transmission, send disconnection instruction

what's the main technology specs of EXTERNAL BLUETOOTH MODULE

A. Transmission Rate: audio 64kbps asymmetrical 721kbps/57.6kbps symmetrical 432.6kbps
B. Interfaces: RS232\USB\UART\PARALLEL PORT
C. Link Type: SCO\ACL,CIRCUIT SWITCH\GROUPING EXCHANGE OPERATION
D. Link Communication Type: Point to Point/Point to multipoint
E. Max Sending and receiving ACL data: 1 K byte
F. Dimension: 9x9 cm G. Frequency Band:2.402-2.480GHz

Which fields does EXTERNAL BLUETOOTH MODULE fit for?

It's widely used in Industry, Agriculture, Medicine, Scientific Research and Military. Specially for developers who know little about bluetooth technology to manufacture bluetooth products. So it will popularize bluetooth products smoothly
