It's great that there's a work-around but you shouldn't have to leave your device discoverable to get BT to stay connected. People that were having problems exchanged their devices and the new ones worked fine in the identical environment meaning it's most likely a h/w problem affecting a subset of devices. Those having repeatable and consistent BT issues still may want to consider an exchange.

SOLUTION

After hours of scrolling through forums for a solution for my Galaxy Note 10.1 2014 disconnecting from a bluetooth keyboard bought off amazon uk (anker bluetooth keyboard), I finally came across a working solution for the annoying keyboard disconnection problem.

I found this app called Bluetooth Keepalive on the Google Play store (cant post link as new user lol). Any of you having problems of the same nature should give it a try as it seems likely that until android 4.4 rolls out OTA for the note 10.1 2014, we're otherwise stuck with an extremely annoying bug!

Hope this helps!!:o

EDIT: For those trying the app, first switch on the device BT, then keyboard's, then once you have a connection start the app from the app drawer. Otherwise the app is useless
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] GeorgeP:
I've tried Bluetooth Keepalive and it didn't seem to make a difference for me. Maybe I'll try again being more mindful of what you said in the EDIT.

What does seem to work is keeping the bluetooth connection alive by connecting and having traffic on a second bluetooth device at the same time. If I start the music player and start playing music (Songs > Play button), then turn on a paired bluetooth headset (which causes the music to stream through the headset), then connect the keyboard... from what I can tell so far, the keyboard stays connected. This seems to work, but I can't tell for sure until I've tried this for a few days, because previously it was working fairly well, but disconnected just enough to be annoying.

Before I tried this, whenever it did disconnect, it always did so when I stopped typing for a second or two, which made it seem like there was an issue with the bluetooth power management algorithm for keyboards. Perhaps the continuous audio stream to the headset forces bluetooth to stay active and therefore connected the keyboard as well.

Even if this does prove to solve the problem for me, I'm am very annoyed with Samsung/Google for putting out a tablet that does not work properly with bluetooth keyboards.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
It's not all devices. Mine has no BT issues either connecting or staying connected to audio devices, multiple BT keyboards, and different mice. A couple of people that were having issues exchanged their N10.1-14s and the exchange worked fine with the same peripherals in the same environment. I've used a BT keyboard for hours at a time with no drops. In fact, I leave BT on so when I turn on the keyboard I can actually use it to wake my N10.1-14. You might want to consider an exchange.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] scrabbles:
Same experience here. So far, no issues with my P600, even when there are multiple bluetooth devices in the vicinity. And I can also "wake" my P600 via a bluetooth keyboard by hitting the shift key (like you would on a regular computer). At this point I have paired my P600 with three different bluetooth keyboards and they have all worked properly, even after the device goes to "sleep."
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] GeorgeP:
You were right! I exchanged mine this morning and the replacement unit has no disconnect problems. I was working on it a few hours today and have not had a single issue! The earlier one must have been defective.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
Pure guess on my part but I'd bet it's an antenna or antenna connection issue with some unknown percentage of devices. Here are the BOMs for the Exynos and S-800 N3s.

The Exynos and S-800 N10.1-14s should share the same parts when they are included/used. From the list, the only ones that could affect BT performance are the RF Transceiver, Wi-Fi/BT/GPS Radio, Antenna Switch Modules, and Antenna Control Modules. And of course the antennas themselves. One of those parts could be coming off the line defective but there's nothing ground breaking in any of the components mentioned and they're all from reputable and high-end manufacturers. Wi-Fi and BT share the 2.4GHz frequency and interference, especially on value devices, is fairly common. So for some N10.1-14s to be having issues and not others I'm guessing the way the antenna(s) are connected or routed are preventing the BT signal (which is weaker than the 2.4GHz Wi-Fi signal it competes with) from transmitting strongly enough to consistently maintain a connection. YMMV. :)

Exchanged It

I had the same bluetooth problem as well. My Apple keyboard kept disconnecting so I exchanged it today and it's working now. No disconnects at all.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] manoscello:
Did you mention the problem to the exchange service? Or you just got lucky and they gave you a working one?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Macallan82:
I exchanged it at Best Buy and told them that bluetooth could not maintain a connection and they gave me a new unit with no more questions asked. The whole process took like 5 minutes.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] manoscello:
So I suppose you were lucky. You didn't test it there , in front o f them to check if the new one is ok. This dame problem with the bluetooth is very odd. I have to send mine to service because I noticed this problem after the exchange expiration date....However I read somewhere in the forum that with the clean rom 1.1 the problem gone, but with the version 1.2 it came back. It is not clear if this is a hardware or a software problem...
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
People have exchanged the exact same model N10.1-14, running the same exact s/w and updates, with the same apps installed and settings configuration. When used with the same peripherals that didn't work with the old one the newer one worked. The majority here have never experienced a BT issue (I'm one). That's a pretty clear h/w problem. It may be intermittent and perhaps CleanROM's influencing the frequency but at the prices the N10.1-14s are selling for I wouldn't want to take a chance that s/w, Samsung's or third party,

may

fix it.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] manoscello:
Well, I will request to give me a new one as soon as possible. I just hope the new one will be ok.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] anthropoidape:
For those experiencing this problem... how frequent is it? I have some intermittent drop-outs but they are fairly infrequent and I am just not sure whether I have the hardware fault or not. It is a bit hard to prove or replicate very definitely. There are drop-outs but they are much less frequent than in the video put up earlier in this thread.

This is in Australia btw. Not sure if the fault is local to a particular area.

The thing is that I have always found BT a bit dodgy but I would really like it to work seamlessly with this tablet as I would like to use it to work while travelling.

I obviously don't want to root to try cleanrom 1.1 since then I will have less chance of getting it replaced.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] GeorgeP:
I had the the problem. It was intermittent and fairly random. Sometimes I could use the keyboard for extended periods without a problem, other times it would disconnect every few minutes. Whenever it started disconnecting, I could typically restore better connectivity by rebooting. Anyway, I got an exchange from Best Buy. Bluetooth on the new one is rock solid. It never disconnects and I'm using the same keyboard (Logitech K810) and same software. I'm in the U.S.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] aznmode:
Does it make a difference if you use a bt 3.0 keyboard? I'll be getting my kb tomorrow with 3.0 so I'm hoping this would make a difference. Unfortunately I bought my note from amazon warehouse and for some reason they don't do replacement and will have to rebuy.

Back to square 1

After spending a good part of this week fiddling around with the tablet due to the problem reappering, i've decided to give up and contact Conrad.de for a replacement unit.Lately a problem with the device not reading my 64GB Sandisk micro SD card has also emerged and thus I really have no other option but to order a replacement.

Really frustrated l have to go through the whole returns process and waitfor the replacement tablet to arrive & all but l cannot live with having a tablet that disconnects from my blue tooth keyboard every 7 seconds!! Anyone else had any luck fixing the issue without having to replace the unit?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] GeorgeP:
I got mine replaced, and it was a hassle setting it up again, but I'd recommend going that route. But prior to getting mine exchanged though, I found a workaround that always worked. The tablet would never disconnect if there was an active bluetooth audio connection. So if I was playing music through a bluetooth headset, the bluetooth keyboard never disconnected. The workaround was:

1. I paired an old bluetooth headset I had with the tablet

2. Set up a Tasker profile that would launch the music app, and start playing music whenever that headset was turned on. (this caused the music app to run in the background and play through the headset). I added an exit task to the Tasker profile to stop the music app when the headset was turned off.

Once that was set up, it was pretty seamless. So to use the keyboard, the only additional step is to turn on the headset before turning on keyboard.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] manoscello:
I just tried GeotgeP s method, i connected my bluetooth headset and startedplaying music, and now my keybord and mouse stay connected. At least we have a temporary solution for this problem. Until i deside what to do or return it,i can use this method.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Solyomszem:
Hi Guys,

The mentioned method works. I am glad, because I have less than 12 hours to unroot and re-stock my Note and travel 80 km-s to a friend who is traveling to Germany, where I had purchased my device. (The local Samsung company would not deal with non-locally purchased devices...) And I am a bit nervous because I have rooted my device and thus tripped Knox. The local Samsung support told me that even though tripping Knox is a software related issue, it even voids warranty for hardware related issues as well. Nice. So without this workaround I would be in a situation where I am a sitting duck for 1 month waiting for Samsung.de to decide my fate... :)

I think I can live with this headset-thing. And I always wanted to learn Tasker. :)
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] anthropoidape:
I am not sure I have the issue. I was using a cheap bt mouse as well, and since I ditched that I have not been able to replicate keyboard failure. If it is still there it is vastly less frequent now. I will keep trying for a while before rooting. Going to get a higher-end bt mouse to test with as well. The mouse and kb will be easy to return if necessary; the tablet will be a nusaince as I "bought" it with frequent flyer points.

Update... grabbed a wedge mouse as well. The bt failure kicked in very obviously and immediately. Basically the system becomes unusable once there is both a mouse and keyboard present via bluetooth. Neither device works right.

I will make a video of it later so you guys can tell me what you think. It seems to me to be no good as it is but I am not experienced with bluetooth.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
I don't think so; HID devices are about as low on the BT food chain as you can go in terms of complexity. I think the radio and antenna in a BT keyboard or mouse would make more of a difference than 2.1<>3.0<>4.0. You can do a search and see what's changed between the three standards. Remember, only things included in a 3.0 device need to be compliant; being 3.0 doesn't mean it offers everything detailed in the spec. And even with the "standards" there's thousands of posts across multiple forums on XDA with people complaining "my BT ______ doesn't connect with my ______ device" while people using different brands of peripherals have no problems connecting to the stated device or the reported problematic peripheral works fine when connected to a different device.

There seems to be a specific issue with the N10.1-14 because the Logitech K810 is frequently sited as both working fine and a fail. It's pretty black and white, if the K810 connects fine to one N10.1-14 there's nothing on Logitech's side that can be faulted if it doesn't connect to others.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] anthropoidape:
To eliminate doubt I've tried two keyboards and two mice now... and two firmwares with factory reset. I will also just try the kb and mouse on some other client devices as well but I am also starting the ball rolling on returning the tablet. I hope it's not a horrible experience.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] anthropoidape:
Guys, I spoke to my seller today. They are going to replace my tablet.

What may be of interest is that the guy said, "I spoke to our supplier and you are right, this is a known issue so we'll send a new one out."

So Samsung must be aware of the hardware problem I think.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] Peter Unger:
Today I had contact to a Samsung guy and he told me, Samsung ist not aware of the problem. After chatting a little bit he gave me instructions to debug the error with a hidden debugging function within the Note.

I sent him the debug log to analyze the issue. Hopefully i get some information soon.

...will keep you updated...

Cheers

I was just testing things right now as I read this thread. Last night, when I first got the kb (poetic case w/kb off of Amazon) I started having the problems with the BT dropping. The problems got better the longer the connection, ie fewer drops.

Today, I was having persistant problems with it and as I was reading the posts, I realized that I had an iPhone 4 sitting on the right about 2 inches away and a Moto X in my pocket about 2 feet away, both with BT on. I tested and turned the iphone off, and still problems. I then turned the Moto X off and now all problems seemed to have disappeared. Either one or both of the phones (Moto X because it also has BT4?) were causing interference, or the timing was coincedental and I just suddenly established a stronger connection. It felt more like it was the phones interfering. I tried turning both of the phones BT back on but the problem doesn't seem to be coming back yet...

Still unexplainable. Maybe I was not able to get the strong initial connection with the interference?

Joining the ranks of the BT challenged!!!

This stinks and it still is an issue. I purchased Note 10.1 2014 tablets for me and my wife. We both have the same cases off of Amazon, since no quality manufacturer has made one yet (read that as Logitech, Zagg or Belkin, for starters) BT cuts out randomly after 12 to 20 seconds of use. It's the same issue on both of our devices. Tried a setting that I found that keeps the BT from timing out, but that was marginally effective. Still having problems though. If somebody has a REAL solution, short of rooting it and voiding the warranty, I'm sure that everyone affected would celebrate this person.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] GeorgeP:
From what I know of the problem, I don't think rooting nor the bluetooth keyboard fix app in the playstore (that requires rooting) will have any impact on this tablet.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
It's only an issue on affected devices. There are plenty of N10.1-14's with perfect BT. I connect to a half-dozen BT devices on a regular basis and have never had a BT drop or failure to connect.

Have you tried other BT peripherals to see how they perform? Cheap Chinese BT imports can have issues unrelated to the devices they are connecting to. I bought a cheap Chinese BT speaker and had to exchange it four times to get one that worked.

People in this very thread that were having problems exchanged their N10.1-14's and the replacement made all their problems go away. If you're sure the problem isn't your Chinese keyboard exchange you and your wife's tablets. Although it's odd that 2 out of 2 have the problem.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] GeorgeP:
An update on mine...I got an exchange a couple weeks ago. The replacement was working fine for over a week. Now, the disconnect problem started happening with the replacement. It started a couple days ago.

Bluetooth keyboard testing

I was curious, so I tested my new chinese keyboard on a nexus 5 with android operating system 4.4.2. I also tested it on a samsung galaxy s 4 with Android operating system 4.4.3. in both cases the keyboard connected. There was no lag, and there was no disconnect.

I was curious. So, I tested my new Chinese keyboard against a nexus 5 running Android operating system 4.4.2. I also tested against a galaxy s 4, running operating system 4.4.3. In both cases the keyboard connected and worked without issue. There was no lag, was there any disconnect. Go figure?
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
It's odd. Some folks are issue free and others are having issues. As an example, a lot of people have mentioned the Logitech K810 keyboard. It works fine for some and randomly disconnects for others. It can't be s/w because because connecting two identical h/w devices should work (or not) universally. I suspected the problem could be the seating of or attachment of the antenna. [MENTION=615393]GeorgeP[/MENTION]'s issue of the problem returning sort of points to that. In use the antenna may have become loose or mispositioned. I travel a lot and may N10.1-14 gets bounced around pretty good. I'm still not having any issues. If it were me I'd keep exchanging my device until I got one that was trouble free. They're out there.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] anthropoidape:
Perhaps the problem come in batches. I agree it makes a second look seem warranted though.

I sure hope my replacement is fine... and that it #$%#ing arrives soon... I want to use it!
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] GeorgeP:
Do you think the idea of the loose antenna consistent with the observation that the keyboard disconnects still never occur when the tablet has a concurrent audio session (e.g., playing audio through a bluetooth headset)? Exchanging and rebuilding the tablet is a time-consuming pain in the [*censored*]. Having two N10.1 2014s in a row (purchased 3 weeks apart) with the problem makes me wonder if I'd be wasting my time trying a third one.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
Just to be clear; I'm just guessing. In 2014 BT isn't exactly rocket science and of all the components/features of a newly introduced device it shouldn't be high on the issues list. Every device forum on XDA has a smattering of BT issues just because there are so many devices connecting to so many other devices that there's bound to be the occasional issue.

Yes, your issue could still be the antenna. Each device you're attaching has its own imbedded radio and antenna. So if your headset has a stronger radio/antenna than your keyboard it might be keeping the connection alive for the keyboard to piggyback off of. Typically a keyboard or mouse are used in close proximity to a device they're connected to so I'd imagine their antennas and radios aren't very robust. If an antenna issue's causing some N10.1-14 to send/receive a weaker signal or one that fluctuates the signal strength of the device being attached could make a difference. I've ruled out s/w as the fact that the Logitech K810 works fine with some N10.1-14's and not others when all devices are running the same s/w points away from it. I you look at BOMs for Samsung devices they don't cheap out or cut corners on components. Assuming the BOM components for the radios in the N3 are the same as the Exynos/S-800 N10.1-14's there's no smoking gun in the component department. If it were a component issue, and the same components are used in both the N3 and N10.1-14, the N3 forum would be screaming bloody murder as there have probably been 10x as many sold. So that leaves the antenna, its placement, or its internal connection. Along those lines it could also be shielding issues on some devices creating interference between the radios but I don't think the N10.1-14's design is that complicated that something like shielding would be affected by assembly and vary by device. All just MHO.

Here's something interesting. If you look at the FCC diagram the Wi-Fi/BT antenna is on the right side (looking at the front of the device) about 2" below the S Pen cutout. The pic of the N10.1-14 opened up shows a double pin connector on the chassis that appears to meet a similar connector on the back of the device on what appears to be the antenna. Those types of pressure seating types of connectors can cause issues in assembly. Both Asus and HTC had huge antenna issues over the past two years using pressure connectors or pogo pins. If someone's connection cuts out try to squeeze the N10.1-14 in the area shown to see if it improves. If it does, it's definitely the antenna connector.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] GeorgeP:
You might be right.

fyi, squeezing the area did not seem to have an impact.

Edit: I thought that system cache clearing might have fix the issue, but it recurred later...deleted that text.
[Galaxy Note 10.1 (2014 Edition) Q&A, Help & Troubl] BarryH_GEG:
Interesting. I hadn't really thought about that much because the BT stack and radios are pretty deep (and protected) in the OS. But it could be possible that some rogue app is holding on to or manipulating the BT connection at the app layer causing problems. But based on the number of issue reports it would be odd if everyone with a problem was being affected by a rogue app. Especially those that did an exchange and seemed happy after re-installing and setting up their devices anew. Including the app(s) that may have been rogue. You're the first report of a successful exchange followed a week later by failure that I've seen.
