We want to enhance the support for Bluetooth mobile phone controls in QCar. So far it is done using AT commands and separate plug-ins/scripts for each mobile phone, which we feel is insufficient, since only a few phones are supported.
The best way appears to be a full emulation of handsfree hardware on the Mac OS X. The idea is following:
- Software written in ObjC (or at least wrapped in ObjC if some C/C++ is necessary)
- Must work with standard Apple Bluetooth hardware
- Must transparently emulate a carkit class device (and preferably headset as well)
- Must use computer's audio in and out for sound
- Must provide the following functionality:
- Retrieve phone information (call status, network status, battery, whatever is available)
- Generate event/notification on: Incoming call, Incoming message, Phone available/unavailable
- Accept call
- Refuse call
- Dial a given number
- Mute the ringer
- Redial the last number
- Initiate voice dialling (with phones that support this function)
- No GUI is required
- Contact synchronization is not required
- Unless absolutely necessary, only standard Apple frameworks should be used
We will pay USD 5.000 for a working prototype with source code and all the transferrable rights (including the right to decide on license we use for distribution) and after that we will pay additional USD 5 for each copy of product using this code that we sell. If more people come with a solution, only the first one gets paid though ;-)
