Bluetooth Car kit module is developed for organizations, companies and individuals 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. Aiming at different Bluetooth mobile phone, the Bluetooth module will switch to different profiles.
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, including dial-up by hand, dial-up by voice, incoming display, answering a call, refusing 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 the pairing information of multi-Bluetooth phones , 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
* Support video and audio transmit
* 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 3.0 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: -25 ~85
Storage temperature range: -40 ~ +85
