MC909X Mobile Computer User Guide

When the mobile computer suspends, Bluetooth turns off.

When the mobile 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.

The mobile 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:

On Windows CE 5.0 devices only, if 

 is running, tap 

 > 

.

Tap  

> 

 > 

. The 

window appears.

Tap a check box next to the profile to load (activate).

The Serial Port profile is always active and cannot be removed.

Tap 

 to select all profiles or tap 

 to deselect all profiles.

Tap 

 to activate the profiles and then 

 to exit the application.

On Windows CE 5.0 devices only, tap 

 > 

 to enable 

 application.

See Services Tab on page 3-22 for more information on selecting services.

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

On Windows CE 5.0 devices, BTExplorer must be disabled prior to changing profiles. Windows Mobile 5.0 
devices do not require disabling BTExplorer.
