Bluetooth Carkit Hands-free Module

Product Description

Bluetooth Car kit module is developed for organization, company and individual who are specialized in developing Car kit hands-free system. It realizes the combination of Bluetooth Headset profile and Bluetooth Hands-free profile as the core of Car kit Hands-free system, which is developed as the Bluetooth v2.0 criterion . It supports any mobile phones with Bluetooth 1.0 or 1.2 or 2.0 criterion. Aim at different Bluetooth mobile phone, the Bluetooth module will switch to different Profile. Bluetooth Car kit hands-free provides PCM/Audio interface and UART interface. The main external controller can realize application of Car kit Hands-free by UART interface, include: dial-up by hand, dial-up by voice, incoming display, receive a call, refuse a call switch freely between Hands-free and mobile phone, acoustics keep silence automatically when talking, talking volume adjustment(*5steps), LED indication etc. And it can memorize multi-Bluetooth phones' pairing information, and multi-phones can use this module in turn dispensing with re-pairing. Feature: * Embedded antenna or external antenna * Effective distance is *0M * Standard UART interface(default setting: baud rate ***0bit/s, 1 start bit, 8 data bit, 1 stop bit, without parity check bit) * Support many kinds of baud rate(such as 9.6k, *9.2k, *8.4k, *7.6k, **5.2k etc), the maximum is 1.**4Mbps * PCM simulate frequency interface * Energy saving automatically mode * Support low power working mode/ high speed working mode * Safe authentication data encryption * Realize agreement: LM, LC, L2cap, SDP, RFCOMM?realize Headset and Hands-free * Profile(Bluetooth Headset Profile And Bluetooth Hands-free Profile) * The Car kit hands-free can pair **7 mobiles * Acoustics keep silence automatically when talking Talk volume adjustment function( volume is divided into *5 steps) * LED indicator function * Support all the phones which are accord with Bluetooth 1.0 or 1.2 or 2.0 criterion external main controller can realize the application of Hands-free by UART interface(UART_TX, UART_RX, UART_RTS, UART_CTS) * Work temperature range: **5 ~*5 Storage temperature range: **0 ~ **5 BTM***4C2P On-Board antenna Without DSP BTM***4C2P With DSP BTM***4C2H With DSP and **0 M antenna
