Specification :

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.
