[[SOLVED]] Configuring RALINK MOTOROLA Bluetooth Adapter in Ubuntu 14.04

After a lot of searching and trials and errors I have found the following configurations that have worked for me:

Problem #1: Bluetooth device not discoverable

Solution #1:  

With Ralink FAE, we found that the radio is OFF and the following command has to be executed to turn ON the device again:

sudo bccmd psset -s 0x0000 0x028c 0x0001

+ reboot

and after that bluetooth work fine (enable and disable in same time with wifi)


Tested on HP DV7-6090EF (Ralink RT5390 Combo Wifi/bluetooth) Driver (http://www.ralinktech.com/support.php?s=2 ) V2.4.0.4  Ubuntu Natty 11.04 64 bits

 Problem #2: Audio Sink Problem to Nokia BH-503 Bluetooth Headset

Solutions #2:

I had this problem recently as I bought a bluetooth speaker and attempted to connect to it with my laptop. It kept giving me "Connection Failed: Stream setup failed". I eventually figured out how to make it work like this.

You need to have pulseaudio installed, which you can check for in Synaptic Package Manager by typing pulseaudio into the search bar. You can install it from there if it isn't already installed.

Next, you need to install pavucontrol, either in Synaptic Package Manager, or by running this in the terminal.

Code:

 sudo apt-get install pavucontrol  

This is the unfortunate part. Every time you boot, you need to run this command in the terminal before any bluetooth devices attempt to connect.

Code:

 pactl load-module module-bluetooth-discover  

You can now go into the bluetooth manager and tell it to connect to the device as an A2DP audio sink.

Now, finally, if you go into the PulseAudio Volume Control, on the Playback tab, you can choose the option to send audio through the bluetooth device.
