[Solved] Can't activate Bluetooth (Broadcom BCM20702A1)
Hi,
I've tried for a couple of days to get my bluetooth to work, but haven't managed to do so...
It's a BCM20702A1 in a X230 Thinkpad.
Gnome just tells me, that it's switched off even if the switch is on ?!?
In one of the many tutorials I read was written to extract, the firmware from a .cab file and place it in /lib/firmware/brcm/:
ls /lib/firmware/brcm/
BCM-0a5c-21e6.hcd # was not sure which naming was right so I added both files
BCM20702A1-0a5c-21e6.hcd
...dmesg tells me:
dmesg | grep -i bluetooth

Any ideas?

Re: [Solved] Can't activate Bluetooth (Broadcom BCM20702A1)
I have the same symptoms on an XPS 15 (9550) with Broadcom BCM20703A1 after updating yesterday. I'd not updated for about week and bluetooth was working fine before the update.
After the update I get the exact same as you - device shows up in lsusb and rfkill, lsmod shows the btusb module loaded and the bluetooth service is up and running without errors but bluetoothctl (and other bluetooth tools) report no devices.
Bluetooth is working fine on my desktop PC at the same level of updates with an "ASUSTek Computer, Inc. Qualcomm Bluetooth 4.1". So presumably it's something specific to these Broadcom chips.
I'd previously added in the firmware you mentioned (downloaded from the link in this post) so I tried removing that but that made no difference.
No idea what to try as bluetooth is a bit of a mystery to me.

Hi, thanks for the reply.
Can you reconstruct which bluetooth packages were updated? In this case maybe a (temporary) downgrade would be a solution?
What's a bit strange, I tried to setup bluetooth quickly ~a month ago and it did not work either, and the driver was installed 3 weeks ago.
Any more ideas?

Re: [Solved] Can't activate Bluetooth (Broadcom BCM20702A1)
Ok well that was easy - I downgraded bluez to the previous version I had installed (5.44) and now bluetooth works again. I was able to downgrade bluez without touching anything else so that made things simple.
My memory may have been off in terms of how long it's been since I did a pacman -Syu, it may have been more than a week, but I'm pretty sure it wasn't as long as a month which makes it weird that it's not been working for you for longer.
So it may be worth your trying an earlier version of the bluez package and see if that helps.
The firmware issue won't matter in terms of just seeing the device in bluetoothctl, as soon as this particular issue is solved the "[NEW] controller blah blah blah" line should appear when you run bluetoothctl (getting it to actually talk to things properly is where the firmware comes in).
But yeah, it seems reasonably clear that *my* problem, at least, is in the bluez package. Whether it's the same problem you're having remains to be seen.
Keep me posted and we'll see if we can get anywhere with this.

Re: [Solved] Can't activate Bluetooth (Broadcom BCM20702A1)
Strange, I thought I made a post that I could solve it as well by downgrading the bluez package....
Just created a bug report:

Hi, I have your same problem on the same PC. I tried to roll back from 5.50 to 5.49, 5.47, and 5.44, but without any luck. I do not see the bluetooth in the rfkill list though. Can you tell me which steps you followed after downgrading?
Thanks a lot

Re: [Solved] Can't activate Bluetooth (Broadcom BCM20702A1)
lincoln_lee, if you are experiencing the same problem, please open a new thread instead of bumping an old one. You can link back to this thread if you think it is relevant. It is better to create your own thread because then you own the thread and can mark it solved once you fix the issue.
