Bluetooth Wifi Module Carkit Hands-free Module
QC-2A1 module is one of our company's industry modules, specially aiming at Carkit Hands-free system R&D, design and production.
Bluetooth Carkit Hands-free Module is developed for organization, company and individual who is specialized in developing Carkit hands-free system. It realizes the combination of Bluetooth Headset profile and Bluetooth Hands-free profile as the core of Carkit Hands-free system, which is developed as the Bluetooth criterion 1.1, It supports any phones with Bluetooth criterion 1.0 or 1.1 and 1.2. To different Bluetooth mobile phones, the Bluetooth module can switch to different Profiles. JINOU Bluetooth Carkit Hands-free provides PCM/Audio interface and UART interface. The main external controller can realize application of Carkit Hands-free by UART interface, including 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, talk volume adjustment(15 steps), LED indication etc. It memorizes multi Bluetooth phones' pairing information, and multi phones can use this module in turn without repairing.
