XPS 13 9370 no bluetooth after suspend
I got a new XPS 13 a couple of days ago. Everything works great with Ubuntu *except* for bluetooth. After a suspend, the bluetooth is lost and doesn't come back. I tried to remove and install the bluetooth driver with `modprobe -r btusb; modprobe btusb` and to restart the bluetooth service but neither things worked. I also reinstalled from factory defaults (just in case) and the problem persists.

I'm done with this machine. Just bought another laptop. Nearly one year, Dell, one year.

I am considering to do the same. The Huawei MateBook X Pro looks like a good replacement with a decent network / bluetooth adapter (Intel 8265 Tri-Band WiFi (Oak Peak) Network Adapter).

Unfortunately this hit me today on Ubuntu 18..04 , rebooting didn't help, Wifi and Bluetooth were gone, since they (as far as I remember) are on the same chip / wireless card they fail then.
Powering off the device and starting it up worked for me.
Anyway, power cycling should not be the solution, and at this price point something this essential should work flawlessly, I mean...yeah RJ45...but... ;)
Dell, please fix this! I had 2 replacement devices and was months without a device I bought...not again....

Brand new Dev machine (9370), latest firmware, 18.04 up to date, same issue you all are facing. BT disappears every 2 out of 3 suspends. A reboot or additional suspends fixes it.
I opened a new support ticket to check on any progress in a permanent fix.

@erik_dell
Try to update ath10k firmware (from kvalo) also. Bt and ath10 are somehow interdependent.
I have latest updates for both firmwares and it seems the issue has been resolved (4 days of healthy sleep with correct awakening). But there is still a chance that the issue will appear in future though.

... that didn't help for my bluetooth issue (no bluetooth device found - ubuntu 18.10). a few reboots did fix it for now. for those that do want to update their ath10k firmware and maybe have better luck than I did:

@amimimor
Have you updated bluetooth fw?

PS Only cold reboot helps

This has been a very anoying problem since I have the XPS13. I have found a workaround that seems to work.

I have also experienced this today. My setup is
XPS13 9380
BIOS = 1.2.1
Release = Ubuntu 18.04.2 LTS
Linux 4.18.0-18-generic #19~18.04.1-Ubuntu SMP
and also I'm running TLP 1.2.2
and my sleep is set to deep sleep:
$ cat /sys/power/mem_sleep
s2idle [deep]
after recovering from sleep, my bluetooth was not recognized. I tried to go back to sleep twice, and it didn't work either. I tried a warm reboot, and it didn't work too. Finally after a full shutdown and starting the machine back up, I finally had my bluetooth back up.

I just tried with this:
https://ubuntuforums.org/showthread.php?t=2423019&p=13890776#post13890776
```
sudo add-apt-repository ppa:canonical-kernel-team/ppa
sudo apt-get update
sudo apt-get install linux-oem-osp1
```
It installed the following kernel:
Linux xps 5.0.0-1050-oem-osp1 #55-Ubuntu SMP Fri Apr 24 11:08:25 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
So far it seems to work, but I haven't really tested it that much yet

sudo apt-get update
sudo apt-get install linux-oem-osp1
which installed kernel:

And it seems to be working so far

My XPS 13 7390 has this issue. I just did a clean install of Kubuntu 20.04 three days ago (format the partition). After many deliberate suspend resume cycles to [deep] state (/sys/power/mem_sleep) and now several normal suspends, I believe it to be much better. So far it has failed to find the bluetooth adapter once. Another suspend resume cycle and it was re-found. So it is not perfect, but for me, so far, it seems to be much better. If things change, I'll re-post.
YMMV

I went into bios and did a reset. Bluetooth is now working.
