Bluetooth is not working in Dell inspiron 3437

Asked by Swamy on 2014-01-02

I got a new Dell Inspiron 3437 laptop with preinstalled Ubuntu 12.04,
the Bluetooth is not working.
"Qualcomm Atheros QCA9565 / AR9565 Wireless Network Adapter (rev 01)" is the chipset in the laptop which supports both wifi and bluetooth.
Wifi is working but bluetooth is not even recognized in the system.

swamydkv@swamydkv-Inspiron-3437:~$ lsusb | grep Bluetooth
swamydkv@swamydkv-Inspiron-3437:~$ lsusb
Bus 001 Device 002: ID 8087:8000 Intel Corp.

Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 0c45:64af Microdia

Need help to solve this.

Try running these commands in a Terminal:

sudo apt-get update

sudo apt-get install linux-firmware

sudo apt-get install dell-dup

sudo apt-get install firmware-addon-dell

sudo apt-get install linux-firmware-nonfree

sudo apt-get install btscanner

Then reboot your PC and retest.

If this does not help, then I suggest upgrading the BIOS of your PC to Dell System BIOS 3437A02 which you can get here:

Here are instructions on creating a bootable USB-stick which allows you to boot DOS and perform a BIOS upgrade after booting a USB stick:

The BIOS is the latest in my system.

I don't think that is a reliable way to check if you have the newest BIOS version.

I suggest booting into the BIOS and checking the release version and release date in the BIOS itself.

The BIOS should show the following release date, if it is the newest version:

Release Date: 11/21/2013

October 28 is not the same as November 21....

Did you execute the steps in post #3?

Did post #3 help?

Correction: here is the newest BIOS release for the Inspiron 14 3437 :

I executed the commands from post #3, but didn't help..

I will try BIOS A07

I didn't understand how to make a bootable falsh drive.

And the Bios file is .exe so how can I create a bootable usb using that file.

See post #5

Thanks Mark Rijckenberg, that solved my question.

Which post solved the issue?

Did the BIOS upgrade to A07 solve the issue?

Or the firmware packages you installed?
