I am trying to pair my Bluetooth speaker with my laptop(model: Dell Inspiron 3542)



I am trying this from over a week now and used every solution found on the internet.



I even tried this solution but it is not working.



Whenever I am trying to search my Bluetooth speaker, it shows me as the following image.

    Possible duplicate of Bluetooth Broadcom 43142 isn't working You can get firmware from github.com/winterheart/broadcom-bt-firmware/blob/master/brcm/… just copy it to /lib/firmware/brcm/BCM.hcd

  • @Marmayogi I have edited question as you asked. output of command sudo lshw | grep -i -A6 "description: Bluetooth" is vanishing while executing it, so cant post that.

I am trying to pair my Bluetooth speaker with my laptop(model: Dell Inspiron 3542)



I am trying this from over a week now and used every solution found on the internet.



I even tried this solution but it is not working.



Whenever I am trying to search my Bluetooth speaker, it shows me as the following image.



Bluetooth forever searching for devices



I am supplying the output of some commands.

I am trying to pair my Bluetooth speaker with my laptop(model: Dell Inspiron 3542)



I am trying this from over a week now and used every solution found on the internet.



I even tried this solution but it is not working.



Whenever I am trying to search my Bluetooth speaker, it shows me as the following image.



Bluetooth forever searching for devices



I am supplying the output of some commands.

keep a note of .hcd file name which is required as shown in the above command output on line 10 & line 22.(which is BCM.hcd in this case)



we can make that file using steps shown here Bluetooth Broadcom 43142 isn't working



OR



you can download it using following commands one by one.



install git if have not yet



sudo apt-get install git


download .hcd file



git clone https://github.com/winterheart/broadcom-bt-firmware/blob/master/brcm/BCM43142A0-0a5c-21d7.hcd


copy .hcd file to /lib/firmware/brcm directory



cp BCM43142A0-0a5c-21d7.hcd /lib/firmware/brcm/.


rename .hcd file with the name which is required(as noted in the command output of the first step) 



mv BCM43142A0-0a5c-21d7.hcd BCM.hcd


shutdown pc(not reboot) & start again
