Troubleshooting

Dell™ TrueMobile™ 300 Bluetooth™ User's Guide

Cannot connect to a paired device

Paired devices are always displayed in My Bluetooth Places, even if the remote device is out of range or not turned on. Verify that the remote member of the pair is within radio range and turned on and then attempt the connection again.

Cannot discover services on an un-paired remote device

The remote device may either not be turned on or it may be out of range.

First verify that the remote device is turned on.

If the remote device is turned on, verify that it is in Connectable mode. From the Bluetooth Configuration panel, click the Accessibility tab and check the mode.

Perform a search for devices to verify that the device is within range.

Dial-up networking service does not start

The dial-up networking service will not start unless a properly configured modem is attached to the server.

Verify that the modem is usable as a local device from the server.

1. In the Bluetooth Configuration panel, Local Services tab,
   double-click the dial-up networking service.
   
   
2. Click the down arrow in the Modem field and select the modem that will be used to dial out, and then click OK.
   
   
3. Click OK to close the Bluetooth Configuration panel.
   
   

How do I determine the Bluetooth Device Address (BDA) of my hardware device?

1. From the Bluetooth Configuration panel, click the Hardware tab.
   
   
2. From the Devices section, select the device for which you want to determine the address. In the Device Properties section, the fourth entry, Device Address, is the BDA of the selected Bluetooth device.
   
   

How do I determine the version of the Host Controller Interface (HCI)?

In the Bluetooth Configuration panel, click the Hardware tab.

In the Device Properties, the fifth entry provides Bluetooth specification compliance information for the Host Controller Interface.

The sixth entry contains the specification revision information for the Host Controller Interface, if appropriate.

How do I determine the version of the Link Manager Protocol (LMP)?

From the Bluetooth Configuration panel, click the Hardware tab.

From the Device Properties section, the seventh entry provides Link Manager Protocol version number information.

The eighth entry contains the Link Manager Protocol sub-version number information, if appropriate.

How do I find information about the Bluetooth hardware attached to my computer?

From the Bluetooth Configuration panel, select the Hardware tab.

How do I test a network access connection?

If the client is hardwired to the LAN, unplug the hardwired connection to ensure that the test checks the wireless connection rather than the hardwired connection.

If the server has access to the Internet, open a browser on the client and connect to the World Wide Web. You may also Ping the server from the MS-DOS® prompt.

Why do I get an Unknown Port message when I try to use a Bluetooth serial port?

The Unknown Port error message usually means an attempt was made to connect a port that was in use.

Additional Bluetooth serial ports can be added if they are required.
