    Bluetooth not Detecting devices and cant be detected

    Hi Community,

    I have just got a new laptop HP15 and have been having some problems with Linux Mint, so have now made the jump to Ubuntu. The overall gui experience is much smoother than with mint, however I have come across a snag and need your help. I have searched the www but cant find a solution.

    My internal bluetooth device is detected with hci, the icon is in the taskbar, but when scanning for bluetooth devices it finds nothing and it itself cannot be found. I have installed blueman and rebooted, there is neither a hardware nor software block in place. I really dont know where to go troubleshooting this.

    Thanks in advance for your tips.

    Regards
    Martin

    Please post
    Code:
    uname -a; lspci -nnk | grep -iA2 net; lsusb; dmesg | grep -i bluetooth; dmesg | grep -i firmware; lsmod | grep bluetooth
    And I will see what can or can't be done

    OK, an easy one
    Code:
    wget https://www.dropbox.com/s/r6q9zt59darq80n/BCM43142A0-0a5c-216c.hcd
    Code:
    sudo cp BCM43142A0-0a5c-216c.hcd /lib/firmware/brcm/BCM43142A0-0a5c-216c.hcd
    Code:
    sudo modprobe -r btusb
    Code:
    sudo modprobe btusb
    And it should work

    Re: Bluetooth not Detecting devices and cant be detected

    sorry to "unsolve" this thread but I have now come across another BT hitch. Tried to connect the laptop via bluetooth to my audio unit but it only connects very shortly then disconnects again. this BT unit is my stereo unit which should act as BT speakers.
    Any ideas?

    Audio over bluetooth can be a pain. Sometimes it can be fixed with
    Code:
    sudo pactl load-module module-bluetooth-discover
    and then pair with the audio. If you are using blueman, it will unload the module every boot.

    Jeremy31,

    Maybe it is time to make a ppa with all Broadcom firmware? It will make things easier for everyone.
