Paired Bluetooth Devices Keep Unpairing

I keep having to reconnect my previously paired bluetooth devices, and I believe this started after upgrading to Marshmallow. Initially, my devices seemed to unpair infrequently, like maybe every 10-14 days. But now, for whatever reason, it is happening more frequently and sometimes daily.
After reading through the forums here and at AC, I thought it might be happening because I rename the devices after I pair them, but that didn't solve the problem when I stopped that.
After Marshmallow, Android Pay required a screen lock to use, which I never had done in the past, so I also enabled Smart Lock and set my paired bluetooth devices as trusted devices. I just disabled all of that (screen lock, android pay and smart lock) so I maybe that will solve the problem, but I suspect it won't.
Anybody have any ideas?

Hi,
I have the exact same issue!
VEry annoying!
Clearing, hard reseting, repairing etc... tried EVERYTHING!
Now i also set smart lock and trusted devices.. Will go to a meeting and back, will test it on the way.

Well, that didn't work for me. I also tried clearing the cache from the boot menu, but it's still dropping my paired BT devices.
My new Square Up Contactless + Chip credit card reader arrived yesterday. Unlike their previous credit card readers that connect through the earphone jack, this one connects through BT. I cannot get it to connect to my XPE, but am able to connect it to my Moto X 2nd Gen.
I really hope this is a Marshmallow issue that will be fixed soon, but the lack of responses has me concerned that it won't.

I tried resetting the network settings and wiping the cache, neither of which fixed it. I decided it was time to do a full factory reset, but that didn't fix it either. Any other ideas?

I going to assume you are unrooted... But either way if you can change your SELinux to permissive that might help your Bluetooth issue there is this app here that might help out

Got the new phone from Motorola a couple of days ago. After reinstalling all my apps and customizations, including renaming my device and the 4 Bluetooth device I connect to, I started to experience the same problem. Not initially, but soon after I turned on the new System UI Tweak option.
So, I turned off the feature and it hasn't happened since. It has been a few days and I have restart (soft reset) several times, which I found would usually trigger the loss of pairing, so I'm keeping my fingers crossed that it was related to the UI tweaker.

Unable to turn WIFI On.

Hi there, I had my phone for about 5 or 6 months where it was fine till recently.
The problem was that I am unable to turn the wifi on. in the main settings the slider is greyed out and a text is on screen saying turning on WIFI but it does not. it does not even show the list of networks. it quick settings it shows as searching but nothing is listed.
in the about phone settings it shows the mac address to be 02:00:00:00:00:00.
This occurred a few days ago but no new software was installed the most recent being a week before to the April security update.
I have tried multiple things such as turning on the airplane mode then off, switching phone on or off, safe mode, factory reset, wiping the cache, taking the sim out.
There has been instances where I am able to connect to a wifi network but it does not last long (few mins) except when taking the sim out which lasted about half a day. (tried again but did not work)
My phone is not rooted and has the stock rom.
There has been some research on this matter where people have done something with the presist(I think that is what it is call) folder but there was no result on it so I have not tried it due to wanted to keep the phone unrooted due to warranty concerns.
I would love some solutions in figuring out this problem.
Thank you for your time.

Have you tried performing a factory reset and flashing the factory images?

Bummer, looks like you've got a hardware failure.

I was hoping it wasn't that

Same problem dont know what to do.... Factory reset\Flash factory img and other not helping at all...

Damn. I had the same thing with my n5. WiFi never showed up to the party. That's why I got the 6p... And the g4.... And the

This problem is exactly what happened to me also, since two days ago. I was searching for a solution and found this thread. Can anyone here who had this problem share how they fixed the issue? is it really a hardware problem?
Thanks!

Help! My Moto G4 Plus wont let me factory reset

So, i just bought from a friend a Moto G4 Plus almost brand new, everything working great.
But this morning i realized my notifications dont show, i cant pull down quick settings, home button and recent screens button are non responsive and i cant see the lock screen anymore; I try to unlock my phone with the fingerprint sensor but it unlocks with any fingerprint or even just by pressing the on button.
With all these problems, I went online to search for possible explanations for all of this. I tried to factory reset it but the button is a little faint and it wont let me. I tried to hard reset it but it also wont let me do that. I uninstalled all the apps i had to see if any app had done this but everything still wouldnt work. Also tried deleting all other information but still, home button and all other things dont work and still cant factory reset.
Also tried factory resetting it with two different programs conectting it to my computer but neither program recognized my phone even though its battery was over 80%.
I am getting really frustrated. I mean, everything else works fine, but all these things should work and everything and its really frustrating trying to use the phone having to go back on everything to go to the home page.
Anybody have any suggestions or have had the same problem? Tomorrow im gonna take it to a guy i know who fixes phones but would really love to know if i can solve it myself.
Thanks in advance

Search here how to flash the stock from for your model. It should fix it unless its a hardware issue.

Just did, and int fixed everything, home buttons working, quick settings are coming down and all the other things.
But, now my network connections are unavailable. My mac address is 02:00:00:00:00:00, my ip address shows as unavailable and my phone also wont read my sim.
I already flashed it again and also tried restoring it to factory setting because now it lets me do it but nothing changes. I cant connect to anything on Wi-Fi, it just stays on the screen of Wi-Fi turning on

I had same issue when memory bocame full! I did hard reset.

Fingerprint scanner not working

Hi, does anyone had issues with fingerprint scanner not working? I updated my software to the latest on A2017U with the October update. After half a day my fingerprint scanner stoped working completely. I tried to reregister it didn't work . I did a Factory reset still nothing its dead .
So its working now by itself, maybe moisture gets in there somehow thats the only thing i can think of. Thanks everyone.

I have issues with mine too, in the past to fix it I have gone into the finger prints settings and deleted all the ones that are there and then rebooted, then you have to setup your prints again. That seemed to do the trick for me.

I couldn't access the device with the fingerprint reader on the first start up after the update, and I also can't access it using the pattern, even though I'm sure I'm entering the right one. So it loos like I have to do a factory reset now

Bluetooth stopped working

At some point yesterday, my bluetooth decided it was no longer going to pair or connect with devices. If I select a paired device that is on, I get a "Connected" messages and then a second later "Disconnected". After this happens the device no longer shows up as paired.
If I go in an try to pair a device it goes through the loop above. I have rebooted the phone several times which does not correct the problem. Everything else on the phone is working. Also, the battery drains fast and a major contributor is bluetooth.
Any ideas? May be time for a new phone :crying:

Maybe a wipe can fix it. Try with another device first.

Yeah, thinking about doing this as a last resort. Thinking maybe the driver got corrupt or something else software related.

Maybe is the regist data, if the driver is corrupt you need to flash the ROM again. But only the modem file.

Have you tried a Network Settings Reset? It corrects about 90% of all connectivity issues in this device...

Where is the network settings reset?

Found it. Did the network reset, but still the same problem.

I still have not done a factory wipe, which I will do this weekend. But if it does turn out to be hardware, is the BT module part of the motherboard, or can it be replaced? I am searching replacement parts and watched the tear-down on iFixIt, but there does not seem to be a separate module for bluetooth.

All,
Here is an update, and not sure if this is pointing to a problem with the ROM or hardware but...
I did a factory reset via recovery and bluetooth functionality seemed to behave properly. I then did a recovery from google which put the bluetooth back into the same state as it was before the reset and the reason I created this thread.
Next, I did a network settings reset. After doing this I was able to add a bluetooth device. When I tried to add a second, it got flaky and was acting like bluetooth was turned off. I rebooted the phone and both bluetooth devices were paired and were able to connect. I then added a 3rd device, and it was back to the way it was when I opened the thread.
What I have noticed, is I can do a network reset and I can always add one device reliably. Adding a second device is hit and miss and a 3rd will always render the bluetooth useless.
After the 3rd device is added, even if I turn the bluetooth, it shows it trying to connect to each bluetooth device except for the last one. It is almost like a linked list is corrupt, or a stack is damaged.
My next approach will be to either wait for 7.x to OTA and see if that fixes it. Or I might bite the bullet and root it with a custom ROM.
Any thoughts?

Here is your problem. Not in system.

Thanks dzidexx. I think it has more to do with the number of devices, since if I do a factor wipe and start adding devices it gets into the same state.

You understand there is a know issue with Bluetooth in the latest Marshmallow build for this device, right? It's an issue in the kernel driver and BT radio firmware.

Thanks for that... I did not know it. But it probably explains why my wife's MXPE seems to continually lose it's BT pairings. Now if we could figure out the random reboots...
(P.S. she's completely stock and unrooted)

Random reboots are a totally different thing, very unusual on a stock MXPE... it is usually an app issue or bad hardware.
Try booting it into safe mode for a day and see if that helps, if it does, it's an app issue, if not then a factory reset is in order and do not install ANY apps and test. if it still reboots then it's defective hardware.

I might be able to convince her to try safety mode for a day or two. But she's adamant about not doing an FDR.
She's too darn stubborn for her own good sometimes.
