bluetooth on a dell latitude d620?

Postby helminthe on Mon Jun 21, 2010 6:29 am

Hi, does anyone have a hint on how to debug the bt module on said laptop? It does work in Windows, and I see various reports that it is supported in Linux https://wiki.ubuntu.com/LaptopTestingTe ... titudeD620 - but hcitool reports 'no such device' and the output of lspci and lsusb doesn't include any 'bluetooth' module:

Linux Mint is funded by ads and donations.

It is my understanding that, in laptops with internal wireless cards, the bluetooth software uses the wireless tramsceiver to connect with external devices. Both wireless g and bluetooth use the same 2.4 GHz frequency band so it makes sense in a tight environment like a laptop computer not to install any extra components.

If your bluetooth worked in Windows, it can be made to work in Mint but we will need more information to determine the best procedure.

What release and version of Mint are you using?

What have you tried so far?

Hello - I run the latest Mint, updated yesterday. Kernel version is 2.6.32-21-generic #32-Ubuntu SMP and I had to install the closed source Broadcom STA driver for the wireless card - otherwise it was listed by iwconfig but it wouldn't list any APs or associate if I specified one's MAC.
As for what I have tried: lsmod / hcitool / dmesg | grep bluetooth. Neither return any device.

If Bluetooth worked in Windows, you have all the required hardware to make it work in Linux. You just need the right software.

If you have a Bluetooth entry in the MintMenu under Preferences, you should be able to select Bluetooth from the menu and get a window that looks like this

Just select "Set up new device" and the daemon will walk you through the set up.

If you don't have a Bluetooth entry in the MintMenu, open Package Manager or Software Manager and search "bluez". This is the Bluetooth manager for Linux. Install Bluez and see if you have a Bluetooth entry in the Menu. If so, click it and proceed to set up your Bluetooth device(s)
