How to fix my Bluetooth in Ubuntu?

Question

Bluetooth in Ubuntu on a dual boot Acer Aspire E5-521 laptop fails with this message:

I also have Windows 10 at the same disk but with another partition and there the Bluetooth is working properly.

How can I get the Bluetooth work in Ubuntu?

EDIT 1

I try to type: sudo /etc/init.d/bluetooth start in the Terminal and I got: sudo: /etc/init.d/bluetooth: command not found

EDIT 2

Typing the command lspci -knn | grep Net -A3; lsusb in the terminal I got the next output:

EDIT 3

I'm following the solution of: Bluetooth Broadcom 43142 isn't working

In step 7 checking if the file name is correct with the command: dmesg | grep -i blue I got the next message:

[ 23.906556] Bluetooth: Core ver 2.22 [ 23.906821] Bluetooth: HCI device and connection manager initialized [ 23.906827] Bluetooth: HCI socket layer initialized [ 23.906831] Bluetooth: L2CAP socket layer initialized [ 23.906854] Bluetooth: SCO socket layer initialized [ 24.034310] Bluetooth: hci0: BCM: chip id 70 [ 24.035305] Bluetooth: hci0: BCM: features 0x06 [ 24.051295] Bluetooth: hci0: BCM43142A [ 24.051301] Bluetooth: hci0: BCM (001.001.011) build 0000 [ 24.074628] bluetooth hci0: Direct firmware load for brcm/BCM.hcd failed with error -2 [ 24.074633] Bluetooth: hci0: BCM: Patch brcm/BCM.hcd not found [ 26.321504] Bluetooth: hci0: command 0x1003 tx timeout [ 26.322983] Bluetooth: hci0: unexpected event for opcode 0x1003

EDIT 4

It seems that the correct name for the .hcd file is BCM.hcd for my kernel 4.15.0-64-generic. Then after I shut down and and shut on my computer I get the following output for dmesg | grep -i blue command:

[ 23.041730] Bluetooth: Core ver 2.22 [ 23.041765] Bluetooth: HCI device and connection manager initialized [ 23.041772] Bluetooth: HCI socket layer initialized [ 23.041776] Bluetooth: L2CAP socket layer initialized [ 23.041798] Bluetooth: SCO socket layer initialized [ 23.170312] Bluetooth: hci0: BCM: chip id 70 [ 23.171306] Bluetooth: hci0: BCM: features 0x06 [ 23.187310] Bluetooth: hci0: marin-Aspire-E5-521 [ 23.187318] Bluetooth: hci0: BCM (001.001.011) build 0270 [ 23.945369] Bluetooth: hci0: BCM (001.001.011) build 0270 [ 23.962274] Bluetooth: hci0: Bluetooth USB module

That solves the firmware problem of the driver for the Bluetooth. Thanks @Pilot6

But still I got the same error message at the beginning of this question. So I decide to try to use my Bluetooth trough the terminal. At the very first I found the following command:

sudo service bluetooth start

And that almost solve my problem; now I can use my Bluetooth properly in Ubuntu. But still remains a little issue: I need to run the above command every time I restart the computer in order to get working the Bluetooth.

EDIT 5 [AND THE SOLUTION]

I run the command: sudo systemctl enable bluetooth That prevents that I have to run: sudo service bluetooth start every time I restart. But now the Bluetooth is always turned on! ( as expected I think) So I had kind of the opposite situation where I have to turn off the Bluetooth every time the Ubuntu starts to save battery energy when I do not need it. Thus I went to Startup Applications Preferences and uncheck the Bluetooth:

And that's it! That completely and finally fix my Bluetooth in Ubuntu.

Do you mean the build-in bluetooth utility? In that case yes I did and also didn't work. — José Marín, Sep 30 '19 at 21:09
I'm a newbie in ubuntu so I didn't use the Terminal I just click on the menu near the wifi icon. My PC is an Aspire E5-521 laptop. — José Marín, Sep 30 '19 at 21:20
Then you have not launched the daemon, which must be added to the Startup Applications list with sudo /etc/init.d/bluetooth start — K7AAY, Sep 30 '19 at 21:23

@K7AAY The terminal shows me the message: command not found when I typet your command. — José Marín, Sep 30 '19 at 21:30
Please edit your question and include the command you typed plus the output you got. — Parto, Sep 30 '19 at 22:27
Please [edit] your question and add output of lspci -knn | grep Net -A3; lsusb terminal command. — Pilot6, Oct 01 '19 at 08:56

@Pilot6 I am following your solution at the "Bluetooth Broadcom 43142 isn't working". Now I'm in step 7 in part "you can always check". And I got a message error. I will edit on the question. — José Marín, Oct 01 '19 at 18:41
Paste the message, select it and click the {} soft button to format. — Pilot6, Oct 01 '19 at 18:45

Thank you Pilot6! That solves the issue of type the command sudo service bluetooth start every time I restart the OS. It remained a last little thing but I can handled by myself. This was a work for the last night and today. I Will edit the question with the final solution and I will give you the check for the answer. I really appreciate your help and the other members of the community. – José Marín Oct 01 '19 at 22:51
