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(15steps), 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 10M
* Standard UART interface(default setting: baud rate 9600bit/s, 1 start bit, 8 data bit,1 stop bit, without parity check bit)
* Support many kinds of baud rate(such as 9.6k,19.2k,38.4k,57.6k,115.2k etc),the maximum is 1.384Mbps
* 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 3-7 mobiles
* Acoustics keep silence automatically when talking
Talk volume adjustment function( volume is divided into 15 steps)
* LED indicator function
* Support all the phones which are accord with Bluetooth 1.0 or 1.2 or 2.0 or 2.1+EDR 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: -25 ~85
Storage temperature range: -40 ~ +85
