Bluetooth simply not working???

Post by kevanf1 »

I have a Hewlett Packard Pavilion dv6 64 bit laptop running an i3 cpu with 4gb of RAM. I have recently updated my OS to Linux Mint 17.3 64 bit with a fresh install, not an over the top upgrade. I was previously running Linux Mint 16 64 bit and had no issues with running bluetooth (built in on this laptop) or pairing with my bluetooth headphones. Today I tried to pair the headphones but it just will not play. I have now installed blue man bluetooth management software and still no joy. If I go into the graphical display from the bluetooth icon on the panel (not the blue man one) I have the option to turn on blue tooth. Ok, I have done that. I cannot make bluetooth (or more correctly this laptop) visible as clicking on the switch does nothing, it appears to be greyed out. I then go over to the next bluetooth icon I have on my panel which is for blue man. The title says Bluetooth Devices. Everything is greyed out. I would have expected to find the options in black to enable me to pair up my headphones.

The next thing I did after searching through some older posts on this similar problem was to run sudo blue-man through a terminal. This is what was output:

Which quite frankly means nothing to me :( I am hoping somebody will be able to make some sense about what is happening and why I can't get bluetooth working with this upgraded version of Mint. Is there a solution?

I would just like to add that I have successfully paired up the same headphones to my 32 bit netbook running Linux Mint 17.3 32 bit edition. So, it would seem to be something to do with the 64 bit edition...

There were a lot of changes to the kernels between LM16 and LM 17. Post the results of

Ok, thank you. Here are the results after entering that code:

I can also confirm that the actual bluetooth hardware is working as I tried running a Mint 17 32 bit live DVD on this same machine. This was to rule out the possibility of hardware failure. It worked and paired straight away.

Can you run the same command on LM 17 32 bit live?

Hope this can be of some help :)

Re: Bluetooth simply not working???

From my very untrained eye it would seem that the difference is in the very last two lines from the 32 bit Mint 17 live DVD.

"[ 156.366476] ieee80211 phy0: rt2x00lib_request_firmware: Info - Loading firmware file 'rt2860.bin'
[ 156.368060] ieee80211 phy0: rt2x00lib_request_firmware: Info - Firmware detected - version: 0.34"

These two lines of code are not there in the installed 64 bit version I have. I presume this is important and my next question would be what can I do about it?

Thank you for the help so far :)

The firmware is for the wifi. I am not sure why the bluetooth isn't being detected in LM 17.3 64 bit but gets detected in LM 17 32 bit. I am fairly certain that your bluetooth is this from lsusb command

Code: Select all

  ID 148f:1000 Ralink Technology
Does the update manager under View/linux kernels give you the option to install a 3.13 or 3.16 kernel in LM 17.3?

Ok, thank you for pointing out those two lines. :)

How do I check for different kernel options please? I am certainly willing to give it a try but have no idea of how to go about doing it :/

https://sites.google.com/site/easylinux ... el-updates on the right side shows how to do it. Once you have a 3.13 kernel installed, reboot and hold the Shift key until the GRUB menu shows up. The use the down arrow to select "previous Linux versions" then select the 3.13 kernel and press enter to boot using that kernel

Cheers. I was coming down with a migraine earlier so wasn't thinking quite straight... Anyhow, I found the list of kernels etc and will have a go at setting it up with a 3.13 kernel. I shall report back with the results tomorrow.

Again, thank you for the help.

Re: Bluetooth simply not working???

Ok, I have installed and set up with kernel version 3.13.0-24-generic This is the same kernel version that is on the live DVD for which Bluetooth fully works. It has made no difference at all. I seem to be missing some options when I click on the Bluetooth icon on the panel. If I try Blueman everything I need to search for new Bluetooth hardware is greyed out as if Bluetooth has not been enabled, yet it has.

Any ideas of what to try next? In the meantime I shall reinstate the previous kernel as it has some security updates when compared to the earlier one that I have in place now.

I have just gone through the installed software (synaptic). There is only one thing different from the live DVD to installed version I have on this machine.

[cinnamon-bluetooth 3.8.7+rebecca] is on the live DVD

[cinnamon-bluetooth 3.8.11+rosa] is the version I have installed on the laptop.

Is it possible to install this older version?

Re: Bluetooth simply not working???

Post by kevanf1 »

I have now tried uninstalling the latest version of cinnamon-bluetooth as detailed above. I installed the earlier version as is used in the live DVD which is of course fully working with bluetooth on this laptop. It made no difference whatsoever despite going for a full reboot to make sure the software was recognised.

I am stumped. I really don't want to uninstall 17.3 and install an earlier version of Mint but that seems the only way I can have bluetooth working. It is a major issue for me as I use these headphones to listen to music/other media while the rest of the family is watching rubbish on the tv. It looks like digging out an ancient pair of headphones :(

When booted into the 3.13 kernel, post the results of the commands again. I am about to recomend that you buy a IoGear GBU521 bluetooth dongle

Re: Bluetooth simply not working???

Progress. Thankfully it does not look like I will have to buy an extra 'dongle'. I did not think it could be quite so easy as simply switching on wireless networking :oops: I did that and suddenly I have the functionality back, the ability to detect and pair my bluetooth headphones. It may seem the obvious thing to turn on wireless networking but first I did not even realise there was a key press for this and secondly I had thought the two chips were separate. I'll also add that I have had bluetooth working fine previously with wireless networking turned off. Go figure?

Now, all I need to do is to find out why I have no actual sound output to those headphones.

Try

Code: Select all

pactl load-module module-bluetooth-discover
Then do the pairing with the audio device

Thank you JeremyB :) that seems to have done the trick :) I can now sit happily listening to music while the rest of the family watch dull soaps :D
