No bluetooth adapters detected?
Post by nikial » Sun Sep 20, 2020 9:54 am
Hi all!
I am using LInux MInt 19.3 Cinnamon for some months now. I had never tried to use the bluetooth until now.
So, bluetooth says «No adapters found». I tried to solve the matter using this suggestion https://www.maketecheasier.com/setup-bl . -in-linux/
https://www.maketecheasier.com/setup-bluetooth-in-linux/0: phy0: Wireless LAN Soft blocked: no Hard blocked: no sudo service bluetooth startsudo apt-get install bluemanNext step was to open Bluetooth Manager but when I tried, I got the message «Connection to BlueZ failed BlueZ daemon is not running, blueman-manager cannot continue. This probably means that there were no Bluetooth adapters detected or Bluetooth daemon was not started.»
I tried to start the bluetooth service using the command
sudo /etc/init.d/bluetooth start [ ok ] Starting bluetooth (via systemctl): bluetooth.service.I would be grateful for any help.

Hello, having similar problem.
I have Acer Aspire 5720, it has a physical shortcut button for bluetooth right above the keyboard. Yet it does not detect any adapter I guess.
Here are my results for JeremyB’s input:

I’ve been using Arch Linux for a while and bluetooth has been working without issues. Now, for no explicable reason, Arch doesn’t detect my bluetooth adapters anymore. I tried doing:
$ sudo systemctl enable bluetooth ,
$ sudo systemctl start bluetooth and
$ sudo systemctl start dbus . I’ve enabled generic bluetooth drivers:
$ sudo modprobe btusb . I’ve installed: bluez, bluez-utils-compat and blueman. $ sudo lsmod | grep bluetooth returns:
