Windows Embedded Automotive 7 Deep Dive: Phone Core and Media Core 14
Automatic Connection
Windows Embedded Automotive 7 can automatically connect to a previously-paired phone,
based on events initiated from applications or phone-related functions initiated by the user,
such as pressing the Send button on the phone.
Automotive 7 supports connection to a phone with an active call. If a call is in-progress at
connection time, Windows Embedded Automotive queries the phone for the phone number and
contact information if this feature is supported by the Bluetooth phone.
Manual Connection
Automotive 7 supports manual connection to a previously-paired Bluetooth device. A user can
select a paired device from the UI and manually initiate a connection. If the connection is
successful, a notification appears indicating that the device is connected. If the selected device is
not found or fails to connect after one minute, the connection times out and the user is
returned to the paired device selection UI.
Automotive 7 also supports manual connection events while automatic connection sequences
are underway. If a user selects a manual connection routine for a paired device during an
automatic connection sequence, Automotive terminates the automatic sequence. If a phone
fails to connect during the manual connect routine, the automatic connection routine does not
automatically resume unless the user either initiates a key-on event or presses a phone-related
button.
Automotive 7 includes a feature that returns a notification of why a particular connection
failed—either that the device is out of range, or that the link key is no longer valid. If the link key
is no longer valid, a UI can be displayed that automatically begins a pairing sequence.
Disconnection
When a connected phone disconnects, Automotive 7 does not automatically trigger the
automatic connection sequence to search for a device. Windows Embedded Automotive
typically does not have any indication as to what caused the disconnect, such as whether or not
a user powered off the phone, selected a privacy option, or manually disconnected the phone.
Therefore, Automotive will not try to reconnect to the disconnected device.
Phone Availability
When a user attempts to perform an interaction that requires a Bluetooth-enabled phone be
connected while no phone is paired, Automotive 7 notifies the user that no phone is connected.
If a paired phone is available, Automotive notifies the user that it is trying to connect to the
phone.
Phone Core Registry Settings
Phone Core is managed through registry key values. These values can be programmatically
modified by applications.
