XPS 15 9570 Bluetooth disappearing
I have been using the laptop with my Logitech MX Master 2S mouse for quite a while and things work just fine. But recently, the Bluetooth is not working very well. The Bluetooth adapter just disappear while I had my mouse connected and used for a while.
And the Bluetooth adapter disappears across ubuntu and windows 10 together every time, which indicates it is a BIOS or hardware problem. The only solution that I found useful is to reinstall the bios update released on 21 Sep, but it only helps for a while.
I found that quite a number of people have experienced a similar situation, yet their solutions do not apply to me.

Hi DrQuant,
Thanks for posting. Apologies that your system is not performing as expected.
Your post indicates you have the same problem as the original poster. Does this issue occur using other bluetooth devices such as speakers, or is it only the Logitech mouse?
Here is information from the Dell knowledge base you may find helpful:

Hi Antiaris! Also I have the 9570 and your own mouse, and I have your same problem. It happened to me once upon waking up in standby these days. I blame the new bios v. 1.4.1, since I have this XPS since 26 July and I took the mouse a few days later and only in these days the problem occurred to me. But if you say that it does to you with the previous version of the bios .... I do not know. As for the MX Master 2S, some small "lag" occasionally occur to me both when I move the mouse and when I scroll the main wheel. Does this happen to you too? I'm Italian and I translate with google obviously, sorry! ;-)17378

I upgraded to a newer version of the wireless firmware and the problems have gone. My Wifi and bluetooth were failing reguarly. (same mouse)
When doing a dmesg I noticed the firmware crashed.
I followed the instructions on:
https://wireless.wiki.kernel.org/en/users/Drivers/ath10k/firmware
Using the firmware
https://github.com/kvalo/ath10k-firmware/blob/master/QCA6174/hw3.0/4.4.1/firmware-6.bin_WLAN.RM.4.4.1-00119-QCARMSWP-1.
But check your version (lspci |grep Network)

Yes!! my mouse lag in some time as well. I have just had the bios updated to 1.5.0 today but the problem persists. Even worse, the wifi dies with the Bluetooth, it makes me feel that the problem is the wifi card itself.

The problem persists after updating the firmware.

I have the same problem with Bluetooth. It will just stop working while typing or when machine hibernates, it wakes up without Bluetooth. I have now made 4 calls to tech support. They seem to fix it temporarily only to have it reoccur.
Dell needs to fix the bios or whatever they need to do resolve this problem. Tech support offers the lame excuse that it disconnects due to RFI. That explanation is utter rubbish.

I have followed the later instruction at
<ADMIN NOTE: Broken link has been removed from this post by Dell>
and for 90% it seems to be working fine. The only times when it sometimes fails is when i close the lid.
New firmware versions seem to improve over time is my feeling.
I hope this helps.
