How do I get a Bluetooth speaker to auto-connect at login?

rated 0 times [ 3] [ 0] / answers: 1 / hits: 6687 / 3 Years ago, tue, october 5, 2021, 3:07:20

Today I installed Ubuntu 18.04 x64 LTS on a Dell Latitude E6410i with Windows 7 pre-installed. I connected to my new JBL Flip4 speaker with Bluetooth 4.2 and with A2DP V1.3, AVRCP V1.6, HFP V1.6, and HSP V1.2, and paired it successfully.

I want to auto-connect to the speaker at login; it should connect every time I login to Ubuntu, but does not.

After study, I found suggestions on the web (like Autoconnect to a bluetooth speaker in Ubuntu 16.04), but I can't find rc.local in my system. Also, I installed bt-autoconnect which does not help.

How should I proceed to resolve this?

Work Around

Note:

Below Procedure Tested with my JBL Xtreme

OS: Ubuntu 18.04

at your present Situation that is you have already paired your BT device and while booting your BT device is On,

after login try this..

Open Terminal and run bluetoothctl

The Output will be similar to this

Output:

pratap@i7-4770:~$ bluetoothctl

[NEW] Controller xx:xx:xx:xx:xx:xx i7-4770 [default]

[NEW] Device aa:bb:cc:dd:ee:ff JBL Xtreme

[NEW] Device xx:xx:xx:xx:xx:xx HUAWEI P smart

Agent registered

[bluetooth]#

In above case "JBL Xtreme" Bluetooth Device is Paired but not yet connected.. So to connect to this device

run connect aa:bb:cc:dd:ee:ff at the prompt [bluetooth]#

Example:

[bluetooth]# connect aa:bb:cc:dd:ee:ff

Attempting to connect to aa:bb:cc:dd:ee:ff

[CHG] Device aa:bb:cc:dd:ee:ff Connected: yes

Connection successful

[CHG] Device aa:bb:cc:dd:ee:ff ServicesResolved: yes

[JBL Xtreme]#

This Means if you can run the command bluetoothctl and then at the [bluetooth]# prompt if you can input connect aa:bb:cc:dd:ee:ff The Bluetooth Device will connect.

So this can be done with a single command in terminal like this, after your first login open Terminal and run this command.

echo "connect aa:bb:cc:dd:ee:ff" | bluetoothctl

Example:

pratap@i7-4770:~$ echo "connect aa:bb:cc:dd:ee:ff" | bluetoothctl

[NEW] Controller xx:xx:xx:xx:xx:xx i7-4770 [default]

[NEW] Device aa:bb:cc:dd:ee:ff JBL Xtreme

[NEW] Device xx:xx:xx:xx:xx:xx HUAWEI P smart

Agent registered

[bluetooth]# connect aa:bb:cc:dd:ee:ff

Attempting to connect to aa:bb:cc:dd:ee:ff

Agent unregistered

[DEL] Controller xx:xx:xx:xx:xx:xx i7-4770 [default]

pratap@i7-4770:~$

so the command echo "connect aa:bb:cc:dd:ee:ff" | bluetoothctl is working..

This means if we can run this command at login without human interaction.. the Bluetooth Device which is Paired and already Turned on at the time of Boot will connect in the above manual way..

mkdir ~/bin (Create this directory if you dont have already.. Otherwise Ignore this step)

touch ~/bin/btautoconnect.sh

gedit ~/bin/btautoconnect.sh

Paste the Below Content:

#!/bin/bash



bluetoothctl

sleep 10

echo "connect aa:bb:cc:dd:ee:ff" | bluetoothctl

sleep 12

echo "connect aa:bb:cc:dd:ee:ff" | bluetoothctl

exit

Save & Close the File.

chmod +x ~/bin/btautoconnect.sh

create a .desktop file named btautoconnect.desktop in ~/.config/autostart/

touch ~/.config/autostart/btautoconnect.desktop

Open the fiel with gedit and copy paste the content below this command

gedit ~/.config/autostart/btautoconnect.desktop

Content:

[Desktop Entry]

Type=Application

Exec=/bin/bash /home/pratap/bin/btautoconnect.sh

Hidden=false

NoDisplay=false

X-GNOME-Autostart-enabled=true

Name=BTAutoConnect

X-GNOME-Autostart-Delay=5

Comment=Starts Bluetooth speaker

Reboot to see the BT Device Connected after login in 10 to 20seconds.. without any Human Interaction..
