Windows Embedded Automotive 7 Deep Dive: Phone Core and Media Core 26
Appendix 2: Bluetooth Pairing Service Registry Key Values for the key values.
Discovery Mode and Discoverable Mode
Discovery mode allows an Automotive 7 device to search for a nearby Bluetooth-enabled device
to pair with. Discoverable mode allows an Automotive 7–based device to be found by a nearby
Bluetooth-enabled device so that the Bluetooth-enabled device may establish a pairing
relationship to the Automotive 7–based device.
When the device discovery starts, a phone or media application activates Bluetooth discovery
mode using the Bluetooth Pairing Core API, which communicates with the Bluetooth Pairing
Service to start an inquiry scan for nearby discoverable devices. When a nearby device is
discovered, the Bluetooth Pairing Service notifies the Bluetooth Pairing Core, which routes a
message to the application for each discovered device. When discovery mode ends, the
Bluetooth Pairing Service notifies the Bluetooth Pairing Core, which routes another message to
the application to notify it that discovery mode has ended.
To facilitate quick reconnection of a previously paired Bluetooth phone, an “ignition ON” event
triggers Windows Embedded Automotive to enter a listening mode so that previously paired
handsets can be reconnected as quickly as possible.
Special Pairing Features
Windows Embedded Automotive 7 includes support for the following features:
• Delayed PIN sharing
• SSP
• HID
• PAN
• Device ID
SSP simplifies the pairing procedure for Bluetooth users, while maintaining or improving
Bluetooth wireless security. Automotive 7 supports the following SSP association models:
• Numeric compare
• Just works
• Out-of-band
Hands-free Phone
Automotive 7 provides robust hands-free capabilities when paired with Bluetooth-enabled
mobile phones. These capabilities include the following:
• Authenticate command and control phones
• Receive service information from phones
• Manage incoming and outgoing calls
• Provide 3-way calling
• Maintain call history
• Receive call information from Bluetooth-enabled mobile phones
Automotive 7 provides the ability to download and access phone book data, in addition to
initiating phone calls using the downloaded phone book entries. This provides users easy and
