I have an Asus X541UJ. When I try to discover for a device the Discover Device Window doesn't shows nothing even if it leaves it open for several minutes. I've already tried to resize the Discover Device Window but same. The same happens using blueman.

The bluetooth seems unlocked:

giuseppe@giuseppe-X541UJ:~$ rfkill list
0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

While when checking the status I have this error:

giuseppe@giuseppe-X541UJ:~$ /etc/init.d/bluetooth status

I have already searched the net but I can not find a solution.

I've also tried to change linux-firmware but it does not change anything, now I have the version: 1.157.18. While for the kernel version: 4.15.0-23-generic.

I am also attaching some general information on my pc if they can be useful:

I had the same issue but i solved it, like this:

1) I checked lspci -nnk | grep -iA2 net; lsusb; dmesg | egrep -i 'blue|firm' it gave me the result Bluetooth: hci0: BCM: Patch brcm/BCM.hcd not found i'ts commonly on combined wifi+bluetooth devices (especially Broadcom) thanks for this post

2) Then i found *.hcd file from here and download it

3) Then I copy downloaded *.hcd file to /lib/firmware/brcm

That's it, Don't forget to reboot after all!

Have you seen this Stack Overflow answer bluez 5.30: “Not enough free handles to register service” error in starting bluetoothd and the thread mentioned there?

  • Thank you for your answare. I solved the problem with an external bluetooth adapter. I think it's a compatibility problem with the internal adatadactor of my notebook. – giuseppe antonio Sansone Jun 30 '18 at 11:07
