Ubuntu: “No Bluetooth adapters found” [closed]



Question:

I'm using an HP 250 G3 notebook with Ubuntu 15.04 32-bit. But I can't use the bluetooth service. It says "No Bluetooth adapters found". My bluetooth status shows:

● bluetooth.service - Bluetooth service     Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled; vendor preset: enabled)     Active: active (running) since Mon 2015-08-17 21:27:33 IST; 2min 2s ago   Main PID: 5952 (bluetoothd)     CGroup: /system.slice/bluetooth.service             â""â"€5952 /usr/sbin/bluetoothd -n    Aug 17 21:27:33 arkya-HP-250-G3-Notebook-PC bluetoothd[5952]: bluetoothd[5952...

Please help.

P.S.: Following is the output given by the command "lspci -knn | grep Net -A2; lsusb" :

Solution:1

I am also a HP 250 G3 user. Bluetooth driver present is Ralink rt3290. I successfully got my Bluetooth working using the module in the link below.

https://www.github.com/dineshraj01/rtbth-dkms

you need to compile it and install it using commands given below

make  sudo make install  

Works like a charm for me. Sometimes on restart bluetooth doesn't work. you can simply remove and add the module again using the commands below and it will work.

sudo rmmod rtbth  sudo modprobe rtbth  

You can also read the instructions on the github repo given :)
