[Q] 4.3 Bluetooth Keyboard - Nexus 7 (2013) Q&A

Is anyone else having issues with their bluetooth keyboard when paired with the Nexus 7? I have an Apple Bluetooth keyboard and it repeats characters, and inserts the spaces out of order.
(Yes I'm aware of External Keyboard Helper, and it does help but it makes my typing laggy)

I can't even get to pair with my Motorola 89451N. I am guessing it's firing off random characters during the pairing security process.

These are exactly the type of issues I was hoping to avoid with a Nexus device. Google needs to up their QA

I have a Logitech Bluetooth keyboard with the same issues. My Bluetooth mouse is fairly unless as well.
Here's hoping it gets straightened out soon...

There is a bug filed with Google which might be relevant, but it doesn't give much hope of quick resolution because it has been open for about a year.
My Logitech keyboard works well with my (non-Nexus) phone with CM10, but a different build of the ROM with a newer kernel has issues.

I've renamed the keyboard file, and I still have issues with characters repeating and lag. I think the issue might be the Bluetooth connection being flaky.
The lag is most noticeable in SSH apps
EDIT: I traced this problem to an issue with WiFi+Bluetooth. When I tether to my phone and turn WiFi off, my keyboard acts as it should. I'm not happy with this workaround, but at least I can get some work done.

maybe try finding a keyboard ime and enabling it so it profiles the keyboard input.

Verified. I stopped using my Apple Keyboard with my N7 for this reason. It worked perfectly with the previous gen N7 (2012).
Thank God CM 10.1 added support on the Nook HD+ last week! Yay for CyanogenMod!!
Ironically, my crappy knockoff Chinese BT keyboards work perfectly. It's the exact same as the Saxony Bluetooth Keyboard on Amazon, but I bought it off the boat from China.
My Microsoft Mouse 5000 is also very sketchy with BT on the N7. Again, works perfectly on Nook CynogenMod, and previous N7 (2012).

I have the same problem with my Logitech bluetooth keyboard. It works fine until I turn on wifi, after which is starts disconnecting and reconnecing every few seconds. It's completely unusable. Didn't have this problem with the same keyboard on my Nexus 10 or Nexus 7 (2012).

Typing this on my HP Touchpad Keyboard. No disconnects or erratic key behavior here. Some of the function keys don't work as expected, but volume up/down, media keys, and power key works just fine in additon to the normal array of keys. Running CM10.2 unofficial nightly 8/12 and elementalX 0.9 kernel. Had stock for like 3 hours so i didn't get a chance to try the keyboard out with that.

So I called Google support (24 hour line) and spoke to them about the keyboard issue
(I too have an apple bt keyboard)
from my understanding of what they told me, bluetooth 2.0 (which many keyboards run on) is running at about 2.385Ghz band while the 2.4Ghz wifi band is there very near it. In fact, it is near enough that it will interfere with the polling.
I asked why it doesnt happen with my SGS4 SGH-I337 (aka AT&T version) and they told me it is because it (the SGS4) is running a Qualcom processor, whereas the N7 (Flo) is running a Snapdragon processor.
Last i heard of the Snapdragon processors, they were integrating Bluetooth and Wifi onto the same processing chip which would make sense as to why we have the bluetooth lag.
The rep advised me to try out and/or get a bluetooth 3.0 or higher keyboard saying that should alleviate the problem. This would make sense as to why some people are having this issue while others are not (such as the logitech K810 keyboard)
Just my 2 pennies

I'm using Microsoft Wedge Mobile Keyboard (BT) with External Keyboard Helper Pro and I don't have any problem.

I'm using the wedge as well. No problems at all.

This is one annoying problem. Have tried all the BT keyboards I have and they all have the repeating char issue.
Same keyboards were all working on my N10 previously on CM10.1 (aka 4.2.2). Have not tried it since updating to CM10.2 since my daily driver is now the 2013 N7. I'm going to try this and see if it is an issue with 4.3 or something specific to 2013 N7.
I have to say it's been so nice taking the BT keyboard for granted. Having to type on the virtual keyboard onscreen is such a pain.

Hi:
My Perixx folding BT keyboard doesn't work with 4.3 period, not on the Nexus 7 2013 nor Nexus 7 2012. My friend is using it on his Nexus 7 2012 running 4.22, not yet upgrading to 4.3.
On 4.3 it pairs but the keyboard won't type anything, a paper-weight.
Tom

So it's quite likely this isn't fixable via software and the only way around it is either to replace the keyboard with a BT3.0 device OR upgrade your router to one which supports 5.0ghz wifi?

I have the same issue with everyone here.
My keyboard is Microsoft Wedge Mobile Keyboard which using Bluetooth 3.0 technology but it no help

Can you have a simultaneous pairing of a keyboard and a mouse or just have them connected one at a time?
What other bluetooth devices have people found work?
I wonder if my magic mouse would work with it.....
I'm using a connectland bluetooth mouse. Working fine. It told me when I connected it I have to use the Samsung ime to use it. However thumb keyboard, swype 3, and the vanilla ime all work too. The scroll wheel doesn't work or right clicking with any of the keyboards I tried.
Edit: I take that back the scroll wheel does work with list views doesn't seem to work in web browsers.
Edit: actually its just Opera the scroll wheel doesn't work in.

Which Bluetooth Keyboard and mouse working on the Tab?

Hi Guys,
I tried apple magic mouse and apple wireless keyboard (old version with number pad) and they both are not working on my tab 10.1 wifi. So I want to know if any of you guys successfully using any bluetooth keyboards and mouse with the tab?
My brother has the new imac keyboards, well not really new but the ones that come with the macs, and it worked perfectly, I just had to set the keyboard on the tab to the samsung one and no issues. As for a mouse, I have no idea.
In my experience, the apple magic mouse connected to the tab, but no cursor appeared, nothing at all. And Apple wireless keyboard (older version with numpad) didn't even connect .
I tested the one without the number pad. Worked great. Try to get your hands on that one.
Anybody had any luck with a BT mouse?
I've been using the Microsoft Bluetooth Notebook Mouse 5000 with my LTE Tab for several weeks with no problems. It's not very sexy, but it's cheap and gets the job done well.
I've also used the Logitech Tab 10.1 Keyboard Case and the Microsoft Bluetooth Mobile Keyboard with no problems. The Logitech case is spendy, but the Android-specific keys are nice, and I doubt you will find a more compact Tab/keyboard pairing, if that's a concern (it is for me).
just tried my logisch dinovo edge it's a Bluetooth Keyboard with a touchpad on it, and it works great, mouse Cursor shows the instant i move it clicking also works! Keyboard input as well

I want this keyboard! I am just looking for the best place to get it from.
And by best place I mean the cheapest.
The apple bluetooth keyboard without the numeric block works great exept some special characters : on the german keyboard layout the @ normally is only accessible with Alt gr + a. This does not work on apples keypad. I read that this was a bug from the Galaxytab, because it works with other android tablets without a hassle.
Still looking for a solution.

Bluetooth keyboard and mouse at the same time

I don't have a Wedge but I have a Zagg Flex BT keyboard and Gearhead BT mouse and have no problems using them together. In fact, I often use my BT Clarion stereo speaker to listen to Tunein radio while I have the keboard and mouse in use. The one thing I do is connect the keyboard first.
I have several brands of BT mice and BT keyboards and they all work together just fine.
I have a bluetooth Ms mouse and a generic bluetooth keyboard with touch pad. If they are both connected, the mouse lags regardless if the trackpad is turned on or not. I am probably going to replace the KB first and see if that clears it up.
Ynt: Bluetooth keyboard and mouse at the same time
I will buy Microsoft Wedge Bluetooth mouse or Microsoft Sculpt Bluetooth Storm Mouse. I read somewhere android system sees sculpt mouse as a bluetooth keyboard. So there should be a conflict. Do you think this is true?

It shouldn't be a problem at all- the "USB HID" protocol (which is what BT mice/keypads/trackpads/etc. use) will sum all devices of the same type (keyboard/pointer/...) so they'll all work together.
(However, the system might enforce exclusive access to a particular type, but I think it only does that for exclusive-use devices like headsets and headphones/)
Ok, I bought the Wedge Mouse.
As I pair it, I can see it as a bluetooh mouse in bluetooth settings. That's ok. But when it connects, a popup says "Bluetooth keyboard connected". I also connect Wedge Keyboard and again get the popup "Bluetooth keyboard connected".
When I use them together, keyboard starts to repeat my key strokes resulting as "Ooohhhhh whaaaaaat's ggooooooinnggg oooonnnnn???". I can also see a little lag for mouse. Like they are using both the same frequency/channel/protocol (whatever it is) and there's a conflict.
What can I do?

That's essentially what the BT spec is doing , but it's OK, they're all made to multiplex together.
For the repeated keys- try changing order that you connect it with when using multiple BT devices
For the mouse-tracking speed, try changing the tracking speed in "Settings" (I wanna say in "Language and Input")
BTW, what Android version is your Note running? (Settings->About Tablet)

I installed External Keyboard Helper from Google Play and it helped preventing repeating keys. But still I feel uncomfortable.
It appears that there is a problem pairing a Wedge keyboard and mouse together in Windows and Android. There may be no fix for Android devices. If you can still return the mouse you might consider buying a non-MS mouse. Here's a link to a thread in an MS forum dicussing the issue you're having. http://answers.microsoft.com/en-us/windows/forum/windows_8-tms/wedge-mouse-wedge-keyboard-repeating-keys-help/069cf8de-da2e-49d1-ad14-128670ac0ccf

There is nothing special about it. When the mouse is paired, it should start scrolling. Are you you using Note 10.1? If yes which android version?

Note 10.1, OS 4.1.2. N8013.
It scrolls like a mouse usually does, but aside from that , the touch features are limited, though I seen on this review it can do horizontal scrolling.

I wonder if I'm doing something wrong or if its the tablet.
EDIT: Checked and the Xperia Launcher is not set for horizontal scroll, but Holo Launcher does it. I will email the developers on this .
I have Microsoft BT Notebook Mouse 5000, noname BT keyboard and BT speaker Bose SoundLink Mini. When i use mouse alone - all OK, it is smooth and fine. But when i connect BT speaker and\or keyboard - i have some lags and pointer moves stroked.
When i connect another mouse (simply wireless 2.4 ghz) via USB OTG - it OK. Phone - Sony Z Ultra (flashed to Google Play edition)
I think, mouse must have upper priority, how i can change it? Thanx!

You can't, but that's not the real issue anyway; I suspect one device's BT radio is out of specification and interfering with the rest. I use a mouse/keyboard/speaker trio quite often and they all play together. Plus, if you're connected to 2.4GHz WiFi at the same time, the WiFi will tend to make BT connections worse when you're actively receiving data, as they share the same band (in the 2.4GHz spectrum).

In this case, my mouse is the device, that interfering It lag with keyboard, and with speaker separetely. With keyboard only lag is litle low. Wifi disabling make lag little low. I know about one band, i was hoping that it frequency modulated(

This works perfectly:
1. MS Mouse 5000 (BT)
2. MS Keyboard 6000 (BT)
This does NOT work - it causes a lag/delay on the mouse - still trying to figure out why:
1. MS Mouse 5000 (BT)
2. MS Wedge Keyboard (BT) - this is a pretty new device - form is pefect, but I'm gonna return it because it makes my mouse not work
Thanks,

I have ms wedge keyboard and ms touch mouse, and they both works fine. For the keyboard I also needed to get the app called External keyboard helper pro to get all letters to work including altgr because android (atleast 412) doesnt understand altgr button and im using keyboard layout (finnish) which have extra letters and some symbols are behind altgr + key.
Hmm.. i think i had an issue too with the mouse jumping around, but the app also fixed this issue. Or was it only with the keyboard workin funny and repeating keystrokes... hmm i think it was actually the keyboard working funny but it was solved by that app.

[Q] Bluetooth fail when Wifi working

Hi, im new here.
I bought a Wireless keyboard (PS3 official) (because logitech unifying via OTG doesnt seems to work), is working fine on Nexus 7 2013 (stock rom, non rooted, JSS15R) when Wifi is disabled or even when wifi on standy, however, just 5 seconds of Tune in streaming and bluetooth gets disabled, keyboard super laggy, etc.
Im not quite sure if is a hardware fail, seems to be a concrete problem with 2013 version when wifi is NOT set to a 5GHZ antenna mode
I made a quick search on internet about this issue and found some threads but i was wondering if you guys here have another or better solution.
Anyone have tried a bluetooth keyboard on 2,4ghz wifi without problems ?
there's a keyboard fix app that fix the issue,try search "bluetooth keyboard bug fix"

Bluetooth Keyboard Connection Issue

Hi all, I just bought a COD (TM) Bluetooth Keyboard Stand from Amazon. The stand is great, but the bluetooth keyboard keep losing its connection, even when I'm typing.
What could be the cause? Does anyone know how to fix this? Your help is much appreciated.
EDIT :
Try this to fix your BT problems .
Go to settings > Connections > Bluetooth > Hit menu button > Visibility Timeout > and change it to Never

Try disabling the onscreen keyboard when connected to bluetooth. Some have reported this to help. I do not know for sure as I dont have BT Keyboard yet. There is some talk in one of the threads here about it. I dont remember where ATM but will look again for it and post a link to it if I can find it.

Thanks for your reply. I tried this trick with no luck. It automatically switch back to Samsung keyboard after 2 second. Grrrrr...very annoying
Google "android 4.3 bluetooth keyboard". Android 4.3 breaks most bluetooth keyboards and it appears Google has no desire to fix it with 4.4 out now. There are fixes out there but they involve rooting and voiding your warranty on this tablet. I think those of us who use bt keyboards and want a warranty will just have to wait for Samsung to roll out 4.4.
I almost returned the tablet over this but I get enough out of it that I'll wait. Hopefully they'll roll out 4.4 soon.

I use my Samsung BT keyboard for hours on end and have never had a single issue with it. If BT is on, my N10.1-14 auto-connects when I turn on my BT keyboard and disables the onscreen keyboard. Samsung doesn't use Android's stock BT stack so any problems in generic Android wouldn't affect their devices. There are quite a few people here that aren't having issues with BT keyboards which would lead me to believe that it's the keyboards that some people are using that are causing issues. Interestingly, I had issues with the same keyboard I'm using now on my N10.1-12 where it would fight with the onscreen keyboard and randomly pop-up accented characters if I typed something like an "a" and left my finger on the key too long. It drove me crazy and I don't have any of those issues with the N10.1-14.
It's not clear exactly what the problem is, but here are a couple of observations, from what I've noticed:
- In some cases, the problem may be related to conflicts with other apps installed. The problem became much less noticeable after i uninstalled MightyText. May be coincidence, but I definitely see a big improvement. I still get an occasional disconnect with the Logitech K810, at most once every half hour of so. When MightyText was installed, I got disconnected every couple minutes.
- I also have a Samsung BT keyboard. I very rarely get disconnects with the Samsung KB.
@BarryH_GEG
I'd like to know where it was published that Samsung isn't using the stock Android BT stack? I've tried numerous keyboards that work with my desktop, iphone, and original GN 10.1 without any issue whatsoever, but are useless with this tablet. All of the symptoms are consistent with what others have reported on android 4.3. Hard to imagine that being a coincidence. Glad you found one keyboard that works. We can add it to the (short) list of ones that do.

Kind of simple really. BT's been broken in AOSP since 4.2.
Bluetooth Is Basically Broken
Known affected devices: Nexus 10, Nexus 7, Galaxy Nexus.
Documented? Android bugs [1] [2], XDA [1] [2], Google+.
We've already received numerous emails about this issue, and I've confirmed it myself: Bluetooth on everything but the Nexus 4 (apparently) is in an absolutely sorry state right now. Audio streams extremely choppily, sounds mediocre, and often loses connectivity entirely. 3rd party Bluetooth apps that create compatibility with devices like the Sixaxis or Wii controllers no longer function at all, and throw an error instead.
This is bad. This is the kind of thing that makes someone return a phone or tablet, because A.) people have no patience for stuff like this, and B.) there's zero reason something as simple as Bluetooth should be broken so badly out of the box. Google needs to mark this one "critical" and fix it ASAP.
http://www.androidpolice.com/2012/1...major-issues-plaguing-googles-newest-release/​
Samsung's 4.2 devices weren't affected which means they had to be using either their own BT s/w or made major modifications to BT in AOSP. As for a "short list," how do we know it's of "working" peripheral's vs. "broken" peripheral's? I've only seen about a half-dozen BT connectivity complaints and really wasn't aware of the problem until it was pointed out to me in another thread. In my case I have about six BT devices I use regularly including speakers, headphones, mice, and keyboards and if asked I'd say they work better on the N10.1-14 then they did on the N10.1-12. I'd define "better" as connecting faster automatically, staying connected, and playing well with others when multiple BT devices are connected. To your point, I could be the anomaly but as posted in this and other threads disabling the onscreen keyboard and checking for conflicting s/w seems to have helped some people so it wouldn't appear BT issues are that widespread (yet).
I agree that the onscreen keyboard adds much to the frustration, as it's default behavior mimics the problems folks have been reporting on other 4.3 devices. Most of what I've come across cites keyboard issues that many have experienced immediately after upgrading to 4.3, but that doesn't really meet the requirements of being evidence either. I suppose the only real way to know would be to grab the base android build that Sammy used and compare files.
As for compatibility issues beyond keyboard input, I can't really speak to that, as I only have a few audio devices and one gamepad. It isn't really a large enough sampling to suggest that the entire stack is hosed up. My issues have been entirely related to BT keyboards, so I'm more focused on that.
You mention conflicting software, which brings up a question. Since the BT stack would be considered part of the protected core OS, apps would require root to mess with it, wouldn't they? The six axis app being a good example, as it requires root. To hook the BT stack at a low enough level to add profiles or override existing ones for compatibility isn't something that should be possible with a user level app. I could be off base here and the reports of user apps affecting BT are an interesting coincidence, but I'm not sure I can quite see where the two cross paths. The alternative is surely more concerning, as it would imply that core OS functions in this tablet are somehow exposed to being overridden by user space apps.

I agree that the onscreen keyboard adds much to the frustration, as it's default behavior mimics the problems folks have been reporting on other 4.3 devices. Most of what I've come across cites keyboard issues that many have experienced immediately after upgrading to 4.3, but that doesn't really meet the requirements of being evidence either. I suppose the only real way to know would be to grab the base android build that Sammy used and compare files.
As for compatibility issues beyond keyboard input, I can't really speak to that, as I only have a few audio devices and one gamepad. It isn't really a large enough sampling to suggest that the entire stack is hosed up. My issues have been entirely related to BT keyboards, so I'm more focused on that.
You mention conflicting software, which brings up a question. Since the BT stack would be considered part of the protected core OS, apps would require root to mess with it, wouldn't they? The six axis app being a good example, as it requires root. To hook the BT stack at a low enough level to add profiles or override existing ones for compatibility isn't something that should be possible with a user level app. I could be off base here and the reports of user apps affecting BT are an interesting coincidence, but I'm not sure I can quite see where the two cross paths. The alternative is surely more concerning, as it would imply that core OS functions in this tablet are somehow exposed to being overridden by user space apps.

Great post and it touches on one of Android's key weaknesses. "Core" like everything else is nothing but a guideline. OEMs like Samsung and app developers color outside the lines all the time for their own benefit. In Samsung's case it was beneficial because BT in 4.2 was a mess and based on your findings still is so Samsung's meddling helped their audience. Android's kind of like the wild wild West in that regard. Add to that something like BT which itself is kind of like the wild wild West with frequent complaints about incompatibility between devices and you end up with the situation we're discussing. In every phone forum I've seen there's always multiple threads on "can't connect to my [insert brand of car]'s BT system." If the phone and car's BT implementation followed prescribed standards that wouldn't be the case. But who knows who's fault it is - the device OEM or the car manufacturer.
Here's another thing to consider about Samsung devices. ROMs from different regions with the same build and change list number released within days or weeks of each other can have different versions of included apps and s/w. As an example, some users on the N10.1-12 forum couldn't import PDFs in to S Note while the majority could. Those that could successfully imported the same PDFs that those that couldn't were having issues with. With some sleuthing we discovered there were almost a dozen different versions of S Note and that two had the PDF issue. And that was with the N10.1-12 being out for about three months. I'm on a Latin American SM-601 so there's the possibility that my BT might be different from U.S. (and possibly other region) SM-600's.
You might want to try a Samsung BT keyboard that you can return if you want to see if the BT issue is pervasive. If Samsung's KB works then you'll know that BT isn't totally borked and that perhaps updates might correct incompatibility issues with other keyboards.
The OEM customizations necessary to fit android to a particular platform is a necessary part of enabling the OS on vendor specific hardware platforms. I get that part, but replacing the entire stack instead of just creating the kernel driver component would definitely be an aggressive move. If this is the case, I would really be surprised that apps outside of the ones Samsung has written or bundled would be able to interfere with it. Maybe I'm giving samsung too much credit by assuming that they would leave the baseline android security model intact, but to deviate from it that badly is asking for a major vulnerability trainwreck. The inclusion of Knox (I won't get started on that in this thread) would imply that they are trying to prevent such a thing.
I obviously don't have the details necessary to speak decisively about what Samsng May or may not have done, but if what you say is correct and they have inserted some other BT stack, KitKat may not help us either. The stock BT stack in it adds support for HID over GATT (HOGP), enabling A number of BT 4.0 LE devices that currently won't work (MS Arc Touch for Surface Pro, for example). I'm hoping we might see an update to 4.4 in Q1 '14, so it'll be interesting to see how an updated release affects BT functionality.
Anyone try the app external keyboard helper?

I gave the free version a shot but it didn't work. I tried some of the steps listed for Samsumg devices as well but no go...

I tried it as well with no luck. Bluetooth keyboard connection is very intermittent. Connection still broken while typing.

I have a logitech k810 bluetooth keyboard and have no issues with disconnects, whatsoever. Maybe its a problem with the keyboards trying to conserve energy?

Could you describe your device details?
I'm having this problem with logitech k810 keyboard and android mouse. I have the pro version of the keyboard helper and it has no effect.
Here is a video of the issue = http://youtu.be/WlCgFQ0cAO0
It is much worse with the keyboard than the mouse. My Note 3 running android 4.3 has no issue with galaxy gear, keyboard, mouse and allshare cast all connected at once. I expected the same out of this tablet. I may be returning this tablet, I do not find this acceptable.
My device is a 32GB white SM-p600 USA version.
BT problem exists at initial boot, and was tested after each incremental firmware update to still be present.

I saw your video (nice nicknames for mouse and note btw). I have the USA p600 16GB wifi only - white. I don't have a bluetooth mouse so I can't try that but it seems to work flawlessly with my K810 keyboard with my limited trials. I haven't done any extensive like write a paper but i've done some messaging and emails. Also i've only tried it with the latest firmware. I'd recommend doing a factory reset, and if that doesn't fix it, maybe exchange it for another unit.

Since there's no possible s/w conflicts and I'm assuming you disabled the onscreen keyboard during your testing it might be the keyboard itself. If your keyboard is older/newer than @ChrisNee1988's it might have a different chip or f/w in it. Peripherals aren't built to exacting standards whereas it's unlikely for there to be h/w differences between two SM-600's built so close together.

The keyboard works great on my note 3 so it's fine.
