I have been experiencing issues connecting to devices over Bluetooth. Sometimes it just works, other times it doesn't work at all, and some times it kinda works but not right.
All of these issues are resolved by restarting the phone, but that isn't a solution because the issue comes back.
3 Devices I have been having issues with
1. S Pen - Sometimes it won't connect to the phone, I get an "S-Pen Missing" message and it will not connect. If I t ry to connect to it manually via nRF Connect (The Nordic Semiconductors Bluetooth App) it tells me that the BLE device has a GATT error. It happens semi-randomly but I can always make it happen by doing #2
2. Car Stereo - This is the weird one, it will connect and play music, but it will not do "calls" if I connect to Discord it won't recognise the car as a Bluetooth device it can route to.
3. Raspberry Pi - This one it appears it will connect to ONCE, and then after a disconnect it will not connect again.
Again, each of these can be fixed by restarting the device, but they happen again after a while. The pen & RPi use BLE, I don't know what the car uses for calls.
Turn off global power management completely in Device Care.
Network reset, reboot and clear system cache from the boot menu.
Ok, I've done a network reset, and cleared the cache partition. I checked Device Care for something like global power management, and I couldn't find anything. Most of the pwm settings are off except the "optomise daily" setting.
I'll let you know later if I have the same issue again.
These, this is a N10+ running on Pie.
To check if you have disabled global power go to Developer options>standby apps, all buckets should show as active otherwise power management is enable.

Are those the only three devices you connect via BT? What other apps do you use that need to use BT (i.e. Galaxy Wear, Apple Music, etc.).
You mentioned "Nordic Semiconductors Bluetooth App." I looked it up. Why do you need a third party generic BLE connecting app? It seems to me that could be the problem. You shouldn't need a third-party app to connect your BLE devices. The S22U's native pairing will work with any BT device that adheres to BT standards.
Try uninstalling the nRF Connect app and see what happens.
The only other Bluetooth devices I have are other in-house hardware, running on SiliconLabs BGM13P chips or NRF52840 chips...
The NRF app isn't a replacement for your bluetooth pairing app, its a debugging app... it can connect to BLE devices and show their GATT profiles, update devices that have Nordic's OTA update code and copy a devices GATT profile to act as a BLE Server.
We use it for testing and debugging.

Ok. I recommend uninstalling nRF Connect anyway. If anything, to rule out the app. How old is your car and the Raspberry Pi? Even though BT 5.2 is backwards compatible, sometimes older BT devices won't work with newer devices. That doesn't account for the S Pen issue though.
I uninstalled nRF connect, and changed all the settings you both recommended. Exactly the same behaviour when I went to leave work. My car stereo would do music but not calls, then when I restarted my phone, it worked. Then when I got home, my S Pen would not connect to my phone, then I restarted my phone and it worked.
Its not a problem of not being compatible, its a problem of something stops working.
Please also note that these devices worked fine together in the past. I am concered that it is either a change made by an update or a Bluetooth chip that is faulty....
OP- Have you debloated at all and if so maybe you've removed something relevant that might be causing these issues?
No, stock image, no OS modification beyond the things that Samsung offers (GoodLock and Stock customisation)
I have our in-house apps for interacting with our equipment (over Bluetooth) installed, but #1 they shouldn't affect anything if they are not open and #2 they don't do this to ANY of our other test equipment.
I would just like to say, that I appreciate the assistance that you are all offering! I have used many forums over the years when looking for support on things and I rarely find a place that is more ready to try and help than XDA forums!

I've seen the issue of the spen disconnecting but only a couple of times and the issue worked itself out within a couple of minutes with me not having to do anything.
I've also have had a couple of wonky issues when connecting a new Samsung phone to my car. I've narrowed down my issue to the fact that when I transfer my data & settings via Samsung smart switch, it includes the details of my Bluetooth pairings. To fix it, I have to go in and delete my Bluetooth phone settings from the car and from my phone and re-pair them.

As cool as I think Smart-Switch is as a program, I actually never use it when moving from one phone to another. The junk that Google drags with me from one phone to the next is already too much, I like to use a new device as a chance to do some housecleaning. So no old-data oddities here.

Hmmm.. Ok. You're probably right about the suspect causes. I know there is a code you can dial to get into diagnostic mode, I just don't know what it is.
The only other option you can try (as a last resort) is to factory reset it. If it is update caused, a factory reset MAY fix it. If you take it to a service center, send it in for repairs, or do a warranty replacement, they're going to factory reset it, or have you reset it.
have you tried running diagnostics in device care ?
or check with this dc
android
Bluetooth test*#*#232331#*#*
samsung
Bluetooth Test Mode*#232331#
I still haven't done a factory reset, but I continue to have the issue.
I have run the BT Test in device care, it always reports good.
I tried the codes, neither of them work as the first one is for vanilla android and the second is for older versions of Samsung firmware.
I've tried completely unpairing from the car radio and re-pairing, disconnecting and connecting from the other device to no avail.

I'm not entirely sold on the idea that it is a hardware fault. It could be a hardware limitation; meaning you cannot connect to more than a certain number of devices simultaneously. I don't know how many BT devices you can connect to at once. I know at least two simultaneous connections (I've only had two simultaneous connections at a time).
You said you have other BT devices in your house other than those three your having issues with. How many are there? How many are you connected to at any given moment?
Is it possible that you have too many simultaneous connections?
When you try to connect to your car.. Did you check under BT connection (your vehicle) to make sure both audio and calls are checked..

Yes, and I've disconnected, reconnected and even unpaired and re-paired the phone to the car.

Unless having multiple connections causes the BT to fail completely, no. Even after turning the car off and walking away, it still will not connect to the S Pen. The only BT devices I use with that phone regularly are:
S Pen, Car (Music & Calls)
At work I develop devices that use Bluetooth and I sometimes connect to them, but only ever one at a time.

I have a 2011 Jeep Grand Chreokee. When I first got the phone, it paired fine and I was able to make and receive calls through the BT. I had this setup for about 1-2 days. I then rooted the phone with the stock ROM only removing bloat ware...now I cannot connect via bluetooth back to the car. It seems to connect then disconnect me right away. Ideas?
I know this seems obvious but have you tried unpairing and repairing the phone to the car? Sometimes bluetooth can get fidgety and most of the time it requires you to repair the device. In my experience that generally solves the issues I have had with bluetooth.
Any time I have factory restored my phone I have had to repair it to any Bluetooth devices it was once connected to. Not sure if the Bluetooth address changes for the phone or not on a reset or ROM change, but it seems to be the case. My Infiniti G37s has Bluetooth and I experienced the same issue as you, pair it again and see if that helps.
Thanks for replies...I tried to repair about 6 different times...same result. It seem that the phone and audio connections both connect for about 2 seconds, then the phone disconnects.
Funny, I wanted to try this but kept forgetting. So I just went down to my garage and tried it, and it paired successfully on the first try. Tried making a call via number/phonebook and it all worked.
I'm rooted running Das BAMF 1.3, and paired it with a '11 Sonata Limited.
So I got it working...but without the phone book downloaded. The issue is in fact when it tries to download the phone book. Need to get another phone loaded up with my contacts and do a sync to get phone book loaded to car.

Did you do anything to get it working?
When the device asked me to allow connection to download the phone book, I declined, only then would it pair properly.
I think I figured it out, I have the Infiniti G37, when I rooted & re-paired the Bluetooth, somehow I ignored the question when it popped up asking to "allow" or "deny" the connection.
Yesterday during the whole 4G fiasco, I reflashed & had to re do everything this morning, when I paired my BT, it asked me whether to allow & this time I clicked allow & my BT connects & stays connected fine now.
My question is, is there a way to delete the BT pairing on the phone without having to completely wipe the phone with a reflash?

nevermind, I just found the answer
http://support.vzw.com/clc/devices/knowledge_base.html?id=39262
just hold down "paired"
I believe the issue is just with the MyGig radio on the Chrysler products. I have a SRT8 Magnum with the MyGig and allowing it to download the address book "Breaks" the B.T. connection. I don't know what the issue is? Perhaps too much information being sent to the MyGig and it "locks up"?
I also have a Ford Focus for a daily driver and allowing it to download the Address Book over the phone has no such issue.

It does it on my aftermarket Kenwood double-din unit, too. I've seen it happen on several Ford units too.

I updated my 430N radio with the latest firmware update and phone book downloaded and BT is working without getting disconnected.
Thanks
Thanks for that info. Although I can't do it as I have the "MyGig" retro-fitted into my 07 SRT. So, if I apply the "official update" I will lose GPS time and a bunch of other things.
But, nice to know it works.

Both my wife and I have SGH-T959V with stock 2.3.6 firmware. We have numerous bluetooth devices these two phones are paired to.
My questions.... Once paired, a device should always show up on the bluetooth setting page (as PAIRED) even if that device is turned off or not within distance, right? What if unpairing has been done from that device?
The Scan Device button is to scan new unpaired but ready to be paired (30 sec or so) devices, right? And it has nothing to do with the paired device list below it, right?
Last question. If I turn off the bluetooth on my T959V and turn it back on, my panasonic KX-TG7745 link-to-cell desktop phone would not reconnect even it is set to auto-reconnect every 1 min. I have to manually connect it on my T959V. That is annoying but is that normal?
The problem I have is I am always losing paired devices on the paired device list on my T959V. Power cycling or removing battery might or might not get every device back.
Anyone having the same problem?
Bluetooth on the stock GB ROMs was wildly unreliable for me. I never figured out what it was, but my Motorola hands-free unit would sometimes not connect, sometimes disappear, and often not connect the audio.
I find that the Bluetooth support on AOKP (and probably most of the ICS ROMs derived from the TeamAcid line) to be greatly improved. Shoot, even just being able to give my Motorola a name so I can tell it from the same model in my wife's car is worth it!
Hi all,
I'm growing increasingly frustrated with this watch because of connection issues.
When I received this watch in January, I was able to set it up no problem. Everything worked great. I just had two issues-
1. The Bluetooth car system would no longer work because the phone would use the watch as the default headset.
2. Google duo would go bonkers when I was getting a call if the watch was connected.
Both of these issues were solved with a solution found here in the forums-by unchecking the option to use the watch for phone connection.
I noticed immediately after doing that that the connection became unstable. I would disconnect randomly then reconnect. As the weeks went on the disconnections became more frequent i.e. Every 2-3 minutes. Then the watch wouldn't connect anymore. Once the watch wouldn't connect anymore neither would my car. Nothing related to Bluetooth would work on my phone. My Tiles wouldn't connect anymore either.
So I went through and deleted all data and cache related to the three Samsung apps and uninstalled the apps. I deleted all Bluetooth connections. Then reinstalled the apps and connected the watch. Within an hour I was still in the same situation. (With no other things connected to Bluetooth.)
I figured out that if I restart my phone everything works again for about 20-30 minutes.
I'm at the point where I don't feel like it is worth keeping anymore. I can't have anything else connected to Bluetooth and I have to restart the phone so often that it just doesn't make sense.
After reading through the forums here it doesn't sound like this is a common problem. Is there something I am missing? Is the watch defective? Any suggestions is greatly appreciated.
Thank you.
You could well find the issue is with your phone and not the watch. I initially used my S3 with a Samsung phone that went bust. I went back to my Nexus 5 and found I had some issues and one app had disappeared from the app store. I contacted the app firm who told me that they were aware of it but it was Samsung that was blocking the app. On going back to a Samsung phone the app was available again and works fine. Can you check your S3 with a different phone?
I also have a S3 and a 6P. Disconnect the S3 Bluetooth from your phone Bluetooth settings and it should connect to your car. You should still see the "Gear S Plugin" notification if you swipe down on the the phone. You should still receive notifications on your phone but the Bluetooth will connect to your car. Connect the S3 to your phones Bluetooth again if you want to answer calls via your watch. Hope this helps.
I have the Mate 9 and the Frontier... when i enter my truck i just press airplan mode on the watch turning off all connection. bluetooth from phone to truck connects 1-2-3....
Clarification
Hi all,
Thanks for the responses. Probably because of my long rambling post there is a little misunderstanding of where I'm at now.
Right now my problem is that my phone can't stay connected to my watch. I have nothing else connected via Bluetooth to my phone. Once it can't connect anymore, I have to restart my phone in order for it to connect again. And then it only stay connected for a couple of minutes before disconnecting.
It is like the Bluetooth gets locked up on my phone by the Samsung gear apps.
Maybe it's my phone. Maybe time to get a Pixel.
Any suggestions are greatly appreciated.
Try this. I do it when I lose notifications. Go to Bluetooth on your phone. "forget your watch" it will disconnect. Reboot phone. Then re pair watch and phone after reboot using your phone and the watch (not the gear app). That usually fixes most problems for me.

I have OP7 PRO running android 10 and stock Oxygen OS (not root).
When I pair my device to my car bluetooth set everything works fine, but once the connection is lost it will not auto-reconnect the next time i'm in my car.
Moreover, in order to connect again i need to do the pairing again (not just select the device from the existing devices list).
I saw tons of threads online about this with no solution, some mentioned they think it's an issue with android OS and not the phone itself (this is supported by the fact that my wife just got a new Xiaomi and have the exact same problem).
Does it make sense that this is a global Android issue and has no fix for such a long time? did anyone experience it and managed to fix it?
I would guess at an issue with the car Bluetooth. May be theres a firmware update for that ?

That was my first thought, but it seems that the issue is on the device side as i can see that after connecting the device doesn't appear in the previously connected devices list.
As if the phone forgets it for some reason.
I've had occasional problems too. I'm using Launcher 10. Just last week, I turned on my wifi before starting my car as usual. It connected, then disconnected 2 times and then was stable. There's been times where I'll restart my car to fix it. It's irritating but who knows what can be done about it.
I have a rooted stock op7pro and I have a Samsung active2 watch that randomly disconnects and reconnects once or twice an hour. I have battery set to all Samsung apps on my phone to not optimize battery usage and I have no idea why it does this.

I have understood that it's also possible that it depend on the order in wich you connect.
You should first have to connect the car to the phone instead of the phone to the car.
Iow have the car lookup the phone
Yes, i head a lot about people with flaky connection but i hope that was the situation, for me it won't reconnet 100% of the times.
Changing the order of connections didn't work.
Hi. In the last couple of days, I used "Bluetooth Audio Receiver" from the Microsoft store to be able to play back music from my S20 FE android 11 device at work. I often step away from my work desk with my phone in my pocket, but yesterday I wasn't able to reconnect my phone via Bluetooth when I came back. Since then I can't connect to my work and my personal PC anymore, even tho I didn't even connect to my personal PC for a while.
I'm able to unpair and pair with said Windows 10 machines, but as soon as I tap the entry in the Bluetooth menu, it says "couldn't connect". I already tried to use the reset for wifi/Mobil/Bluetooth within the android setting, but it didn't change anything.
Restarted my phone and both PCs multiple times. It feels like something in my phone hang itself. I'm still able to send files from my PC to my phone and vice versa. I'm still able to fully use my smartwatch and Bluetooth headset.
Is there anything I can do? Any ideas?
PS: My phone is rooted.
Edit1: I just deleted cache and data of the Bluetooth app and did another reset of my network settings. I now can't pair with Windows 10 anymore. It says "couldn't connect" after the pairing dialog. My Win10 Device recognizes my Android device as paired. Which means I can't even send or receive files at my phone from my Windows 10 devices.
Edit2: My headset was still paired. Is there a way to reset saved pairing and data related to that?
Edit3: I don't know why I couldn't pair with my Windows device anymore, but it works again (Didn't do anything). Still can't connect to it, but can send files again.
TLDR:
Android 11 S20 FE can't connect to multiple Windows devices anymore with the massage: "can't connect".
UnPairing and pairing again won't help
Restarting effected devices won't help.
Resetting network settings won't help.
Nobody has an idea what it could have triggered it or what I could try to do?
Any idea is much appreciated.
