Bluetooth Power States

Cold Boot

When a cold boot is performed on the vehicle computer, Bluetooth turns off. It is normal to see the Bluetooth icon
appear and disappear, as well as a wait cursor, when initialization proceeds in all modes.

Warm Boot

When a warm boot is performed on the vehicle computer, Bluetooth returns to the disabled state (off).

Suspend

When the vehicle computer suspends, Bluetooth turns off.

Resume

When the vehicle computer resumes, Bluetooth turns on if it was on prior to suspend. Note that any Bluetooth
connection that was dropped during a suspend needs to be reconnected after a resume.

Bluetooth Profiles

The VC5090 vehicle computer is loaded with a number of Bluetooth services profiles. These profiles can be loaded
or removed from memory. If a profile is not used, it can be removed to save memory. To load or remove profiles:

1.

If

BTExplorer

is running, tap

>

Disable Bluetooth

.

2.

Tap

>

Programs

>

BTProfileSelctor

. The

ProfileSelector

window appears.

NOTE

When the vehicle computer is placed in suspend mode, the Bluetooth radio mode powers off and the piconet
(Bluetooth connection) is dropped. When the vehicle computer resumes, it could take up to 10 seconds for
the Bluetooth radio driver to re-initialize the radio.
