Problems with Bluetooth built into BCM4313 WLAN card

Problems with Bluetooth built into BCM4313 WLAN card

[mail+bluetooth]

Hello,

In my Laptop, I have the following WLAN card built in:

# lspci | grep Wireless
02:00.0 Network controller: Broadcom Limited BCM4313 802.11bgn Wireless Network Adapter (rev 01)

The Bluetooth part of this adapter "somehow" seems to be available:

# rfkill list
0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: ideapad_bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no

While the WLAN part works well, I don't have access to the Bluetooth part of this card. It is not visible anywhere, so I currently have a small USB Bluetooth stick on my laptop.

Is this a known problem? Can someone give me some information if Bluetooth should work and if so, how to get it working?

Thanks in advance.

Manuel

is this wired via USB or maybe via UART. I would check the ACPI tables and see if you have a Bluetooth entry there. If it is USB and they are using a kill switch to disconnect it from USB bus, then rfkill unblock bluetooth and then lsusb and check if it shows up.

Hello,

I've tried with unblocked bluetooth but don't get anyting in lsusb:

# rfkill list
0: ideapad_wlan: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: ideapad_bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
3: phy0: Wireless LAN
	Soft blocked: no
	Hard blocked: no
[root@manuelslaptop ~]# lsusb

Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub


The WLAN part is also not the greatest (open source driver).

I've ordered a new card with Atheros chipset some days ago and will try if this solves this issue.

Then use acpidump etc to look at your ACPI tables and see if a Bluetooth UART device is described there. There is sadly no simple lsacpi to list your devices.

What is the WiFi chipset anyway? Is this Realtek based or what?

Hello,

my acpidump output doesn't seem to have anything about "bluetooth" and I even don't see anything about my BCM4313 card.

About the Wifi chipset, I think it should be Broadcom (BCM4313)

I've tried to load the "thinkpad-acpi" module, but sadly it doesn't detect my ideapad laptop. No way to configure Bluetooth there. I also don't have bluetooth in the BIOS setup to enable it there.

If I'm right, then ACPI/BIOS can somehow block Bluetooth and so even if I get my new card, Bluetooth could still be disabled?

Is there any other way to enable Bluetooth besides booting Windows on this machine to do it there?

Hello,

My new WLAN mini PCI card has arrived and is installed into my laptop.

I hope this at least fixes the unstable WLAN but unfortunately Bluetooth keeps absent.

While searching, I've found something that may be interesting:

Oct 20 11:08:07 manuelslaptop kernel: usb 1-1.3: Product: Bluetooth USB Host Controller
Oct 20 11:08:07 manuelslaptop kernel: usb 1-1.3: Manufacturer: Atheros Communications
Oct 20 11:08:07 manuelslaptop kernel: usb 1-1.3: SerialNumber: Alaska Day 2006
...
Oct 20 11:08:07 manuelslaptop kernel: usb 1-1.3: USB disconnect, device number 3

So yes, on this card the bluetooth controller is connected via USB. I just cant see it in lsusb as it, for some reason, disconnects itself. I have no idea what is causing this...

Maybe I should just stick with my USB dongle. Linux and MiniPCI Bluetooth doesn't seem to be a good combination.

Hello,

unfortunately, I forgot two lines, showing the vendor and product:
