Latitude D820 355 Bluetooth Drivers

I don't have F2 as a function key; I have the enable/disable switch on the side of the laptop. I made sure that the switch was set to enable/disable the Bluetooth in the BIOS as well, and once Windows was up and running, I switched the switch a few times to see if the software would pick it up. The software never did find the Bluetooth module, nor did the Bluetooth LED turn on.

If bluetooth is enabled in the BIOS, but it doesn't show up in Device Manager, then I'd say it is either a problem with the bluetooth module or the slot it is connected to.  I wish I had a different answer for you.

I'd recommend contacting tech support to see about getting it replaced (unless you did not buy it from Dell).  You will need the order number for the bluetooth module when you call since it won't show in our system under the service tag for your computer.

I was thinking along the same lines; I tried to install this in my Inspiron 1318 with the same results.

So which Bluetooth Module should I get for this Latitude? I'm not sure what the difference is between the 350, 355, 360, etc is; there are so many different versions of each with different part numbers, and none of the ones I have seen on Dell's website have my D820 listed as "Compatible". How do I find the correct one and or know that it will be compatible with my machine?

Hi Larry,

Yes, I have made sure that Bluetooth has been enabled in the BIOS before I installed the module or tried to install the software/drivers.

Fn+F2 to twiddle the radio?

The one you have now should have worked, which is why I recommended having it replaced for failure.  The fact it failed to work in another computer that supports it just backs up my belief that it is a hardware failure in the bluetooth module itself.

So is it safe to assume that if the module fits the cable in the laptop, it should be compatible with the correct drivers?

Good to know. Well, I will get on RMAing that, get a new one, and see how it goes.

Thanks Larry

Not quite safe.  I happen to know that particular module does work, however.

Did you try downloading BCM2045 driver? In my opinion the Toshiba Bluetooth Stack is garbage. Go with the Microsoft default program and you only need to load the driver which can be found here:

BCM2045 driver

Yes, I did try those drivers.

If I am not mistaken, the Microsoft and Toshiba bluetooth stacks are designated for their respective OEM equipment, ie, if a bluetooth device was designed to work with the Toshiba Stack, you must have the Toshiba Stack installed to use it, not the Microsoft Stack and vica versa.

The Microsoft Stack is nice in the regard that since it comes built into Windows XP SP 2 and up, any device built for the M$ Stack will work out of the box (like BT M$ mice and keyboards).

The Toshiba stack, is a huge install, is a picky program, and has some quirky problems, but seems to offer many more options for me to configure my BT devices with.

Anyways, my experience with Latitudes in the past is that they use the Toshiba stack, not the M$ one, is this correct?

I'm not in any way an expert with BT, so if anyone knows more and sees an error, please let me know. :)

What were your results with the drivers? I have the same bluetooth module as yours and I got it working with the M$ stack. Initially I installed the Toshiba stack and drivers but when I try to use my Dell bluetooth mouse, it kept turning on and off the bluetooth radio repeatedly so a prompt came up "Are you sure you wish to disconnect the bluetooth device? Turning it off will cause your bluetooth devices to not function. - YES, or CANCEL" So I uninstalled, did a little research and found drivers for the BCM2045. I figured to look up this driver because that is the name of the driver prompt that came up during the new hardware wizard when I installed the bluetooth module. The link I provided IS for WINDOWS VISTA but I was able to get around the setup error by pointing to the driver folder in the 32bit version of Vista. The problem you described was not being able to see the bluetooth module in the device menu which makes the bluetooth module not functioning. For me, after installing the BCM2045 I was able to finally see the module in the device menu and got it to work with my bluetooth mouse using the microsoft stack. hope this helps.

You might need to get windows to re-detect the installation of the module in order to point to the driver manually. You can do this by doing a Scan for Hardware changes in device menu and if that doesn't work you can physically remove the device and re-install it. Another way I got the prompt was installing the Toshiba stack and uninstalling it and when the drivers rollback it will give you the BCM2045 hardware wizard prompt.

jasonchocert,

Apparently I did not look very closely at the link you provided. I have not used the driver you linked to because I am using XP Pro, not Vista.

In any case, I have yet to receive the replacement BT module (shipping confusion, long story). Once I get the replacement module I will try this all again, see what happens, and post back here. Thanks for your help.

Hey, I got it working!

I started with this search on the Dell site.

First, I installed this little utility.

Once this was installed, XP's Device Manager immediately found and listed the BT module. Since the OS was now able to recognize the module, I was able to install the WIDCOMM Bluetooth Stack Software, of which I found 2 versions for XP.
