I have a strange problem with my built-in bluetooth adapter. It was visible when I installed trisquel first time. Then disappeared after reboot. And bluetooth manager shows bluetooth adapter not found. It was working properly in ubuntu.

Can anyone help me?

I'm using trisquel 5.0 on hp probook 4230s

I'd point you to our documentation although I'm not sure it would help. Try adding/removing the bluetooth dongle. Use the +/- arrows from preferences. Bluetooth in general can be a tricky beast.

Another thing to note. Some devices like wireless bluetooth keyboards can't be used with multiple operating systems/computers. The code you enter on the keyboard is held in the devices memory and scrambles the signal so others can't intercept it as easily. However since the code is produced by the software and entered on the keyboard I know of no solution. There is no way to manually enter that code into the desktop software as far as I know. You may be able to find a hack. Possibly copy the bluetooth configuration files and/or examine them. You may be able to find the line / edit it manually.

First note that I'm using trisquel 5.0 .There is no +/- arrows. Then it is problem with detecting bluetooth adapter itself not with any particular device.
Here is my adapter information taken using lsusb command

The chipset is actually AR30xx and it's a USB chipset not a Mini PCIe chipset despite being on a Mini PCIe card. The 802.11 portion is a Mini PCIe chipset. The Mini PCIe slot has to support the USB function to use these cards. The USB chipset here is not free software compatible.

I was also mistaken about the +/-. That might have been Trisquel 4.0.1 LTS. I just wrote up some new documentation today. It's actually a remove button in Trisquel 5.5 if I'm not mistaken.

I've the same adapter and it does the same trick.. Trisquel usually doesn't recognize it and when I shutdown I can read "Deblobbed - Free firmware missing".. but sometimes it "works".. yesterday I also connected my laptop with my symbian phone..

I use Trisquel 5.5 with Linux-libre 3.3.

The Atheros bluetooth chipset needs a non-free blob. It won't work without it. I can conceive of a few explanations for why it may have worked in Trisquel. For example it might be if you have booted up another distribution or operating system with the non-free firmware that distribution has loaded it already. If you reboot it may stay on the chip. If you shut down and then start up the system Trisquel won't be able to utilise it. The AR9285 chipset (wireless portion) holds the firmware on the chip and no firmware loading is required.

We sell USB bluetooth cards to resolve this problem. There is a CSR chipset that is compatible with Trisquel and other free software distributions. Not all USB adapters with this chipset work though. I'm not 100% certain why. This is the case even where the IDs match exactly.

I've only Trisquel on my ssd, but shortly before I had tried Mint in live.. you could be right.. :)

If Atheros legal goes ahead and approves a request to release the firmware's source code for a newer Atheros wireless N chipset we will probably try and get them to do the same for this chipset. No idea what the time frame would be. My best guess is 6-12 months if it happens at all.

This is something we want to do though. Right now we are dependant on a USB adapter which is less desirable (just because it uses up one of your USB ports). Although on the plus side our USB bluetooth adapter is very tiny so it isn't a nuisance.

One other thing. There are some reports on the web that there is a free software compatible mini pcie chip. It is atheros wireless with atheros bluetooth. This is not correct.

It appears a few people have made the mistake of believing they were installing a free solution from a driver when only the driver portion was free. The firmware portion was not. And/or in other cases they may have not tested the bluetooth portion and assumed it was also free. And lastly the one mentioned above may also have occurred in a case or two where a non-free operating system loaded non-free firmware to the chip and after a reboot no firmware in Trisquel needed to be loaded for Trisquel to use the card. In any case there isn't a solution to the problem yet...

I use a micro bluetooth adapter similar to
https://www.thinkpenguin.com/gnu-linux/penguin-usb-bluetooth-micro-adapter
i was worried that libre kernel may not run it but everything is good.
I am also able to use my phone as modem via bluetooth when needed!
After running "lsusb" command i found out it showed
Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)

Yea- you definitely want a CSR chipset. Some of the CSR chips don't seem to work even though the IDs will be identical between chips. There must be slightly different versions of the same chipset being used. Even by the same manufacturer(s).
