Hi,
Trying to configure and install the kernel and I'm confused with bluetooth adapter on the laptop. I can't understand if there is an adapter on my laptop or not.
The laptop is Lenovo b590 (20206)
According the specification there's no bluetooth on it:

But, BIOS tells me that there is the one:

I tried to find the answer in command line, but there is nothing:

Here we can see Bluetooth module. But, as I know BCM43142A0 is the wlan adapter module driver, isn't it?

How to make sure if I have the Bluetooth?

aar,

Welcome to Gentoo.

What does lsusb show?
You get that from usbutils.

WiFi and Bluetooth are often combined as the both use the 2.4Ghz Unlicenced Mobile and special care needs to be taken so that they can coexist.
Indeed, they may both share the same antenna and transmit/receive hardware.

Even if you have bluetooth hardware, it may be disabled.

The Broadcom site says that you have Bloetooth capable silicon.

It seems it's on:
Code:
aar@gentoo ~ $ sudo rfkill list
Password:
0: tpacpi_bluetooth_sw: Bluetooth
   Soft blocked: no
   Hard blocked: no
1: hci0: Bluetooth
   Soft blocked: no

Yes, it seems I have the Bluetooth adapter. Thanks a lot!
So, in menuconfig should I select only Broadcom protocol support or anything else? (see the menu )
