Can anybody confirm that they are having the same problem on their Galaxy Tab 7.7? If I use a bluetooth keyboard, it pairs and sets up and works fine, but if I don't press any keys for exactly one second, then press a key, there is a latency of about 0.5 seconds for the key press to register. I don't have this problem on my Galaxy Nexus, and I can recreate it with both a bluetooth keyboard and a wiimote connected through bluez ime. However, if I connect the wiimote as a non-hid device through wiimote controller, there is no latency after however many seconds. I believe there must be some latency setting to save power, but am not sure. Can anyone advise? I play games with an external keyboard, and it really messes me up. Thanks!
I haven't timed it, but I haven't noticed any latency or issue with my Bluetooth keyboard.

Could you perhaps let me know which model you have (3g or wifi) and which firmware you're running? If you could just test to make sure that the keyboard responds instantly after not being used for about five seconds, I'll flash mine to whatever you have and be forever grateful.
i am also experiencing this, but i am using like a $12 bluetooth keyboard so i just shrug it off since im not bothered by the lag anyway

Good to know that I'm not alone. Hopefully ICS will fix it. I know my galaxy nexus doesn't have this problem so I can only keep my fingers crossed. It wouldn't bother me for text input, but it bothers me hugely when trying to play games, so we'll see if anyone knows how to fix this. Thanks a lot for confirming though.
I'm using a Logitech bluetooth mouse V470 and it's really fast, yes there's a little lag when I stop using it for a few minutes but it's so little that doesn't really bother me. I cant tell you right now about a keyboard, I'll test one tomorrow with and without the mouse and we'll see what happens... I'll get back to you...
Thanks. That's the only real problem with mine right now. I've tried only the Hong Kong firmware, but I don't see there being a difference in the other ones. I imagine that if it's possible to disassemble one of the APKs related to bluetooth and change a timeout value it will work, but I have no idea where to look for such a file.
I connected the bluetooth mouse and a keyboard and they both work great simultaneously, and yes, there's always a delay after you stop using then for a moment but doesn't really bother me...

I'm using a Hong Kong one, and also experience the lag after I stopped using it for awhile. This also affects my Phonejoy game controller at times unfortunately.
Really hope, ICS will fix this.

Same here, it bothers me, but seems it's some general bluetooth go to sleep or whatever issue, after not typing for a couple of seconds, the first keystrokes fail to register for a second or so.
I noticed identical behavior with the Samsung Note.
Glad I found this thread, because I couldn't find anything else anywhere with Google. There's a similar thread in the 7.0 Plus Accessories forum. I can confirm that I'm having the same issue, only with the Galaxy Tab 7.0 Plus. Same exact issue. I'm using both the iControlPad and a keyboard, and the issue manifests itself with both devices, so it's got to be the tablet.
I also noticed that, if a key is held down for too long (I think 3+ seconds), the corresponding action or letter will repeat for a second or two (very noticeable when playing platformer games). If that same key is held down for a shorter period (say, only 1, maybe 2 seconds), then the action or letter will cease repeating immediately after I let go of the key.
Submitted a request to Samsung to fix this, and you may want to do the same (not sure if it will help, but doesn't hurt to try).
Mobile gaming was one of the reasons I got this tablet, and games are nearly unplayable with this delay that is introduced. I'm using the same bluetooth devices with the Motorola Razr Maxx, and these delay issues are not present at all (in fact, the response with using a controller is near perfect). Hate to say it, but I will be forced to look to other tablets if this doesn't get resolved with the ICS update (and I won't get my hopes up).
I can confirm that with the vanilla ICS bluetooth implementation in the Galaxy Nexus, this problem isn't present. I actually sold my Tab 7.7 because of this problem, among other various small bugs, like programs randomly disappearing (of course it's rooted, and I can't say if this happens when not rooted).
Hopefully when ICS is released, if it does have the problem, there will be an AOKP or Cyanogenmod port which will resolve it. Sadly, I don't want to wait for that. Perhaps anyone with an SGS 2 can confirm if this problem is present in Gingerbread and in ICS, or only in gingerbread. Someone with a note could do the same.
Posted this in the 7.0 Plus thread as well. Called Samsung's support line after reporting this by email. I would normally think that this would lead nowhere, but their support line seems to lead to knowledgeable people who at least understood what I was saying (and this seems to be a very specific issue). The number is 1-800-726-7864.
I reported the issue, and I also mentioned the 7.7 tab and the Note. Not sure if that will lead anywhere, but it doesn't hurt for more people to report this.
Also asked about ICS... crickets of course
So my hope to c0nnect keyboard n mouse. Hdmi output and charging at the same time is gone.

I just recently bought a white galaxy s2 from newegg. I have an MHL to HDMI cable incoming, and when I saw that you could use a mouse with the device, I was really excited.
link: I'm too new to post links, but search google for "magic mouse samsung s2" and the youtube link should pop up first.
However, even though I am able to pair a mouse (I've tried a magic mouse and a mini presentation Microsoft Bluetooth mouse so far) when it connects, it instantly disconnects... and it keeps doing that over and over.
Bluetooth is able to keep a connection with other devices, like a headset and transfer data over bluetooth to my computer.
When I called Samsung support, first the girl didn't know connecting to a mouse was possible, and upon seeing the video, her response was why would I ever want to do that, and there was nothing she could do to help.
I saw other threads mentioning bluetooth problems could be fixed with a factory reset, but after doing so I have identical behavior. I don't think its a hardware issue, and I applied the newest update 2.3.5... I'm really confused here. What should I do? Any other details required? Maybe my magic mouse just doesn't like my phone?
From what I have heard apple magic mouse does not connect correctly.do you or a friend have a different bt mouse to test?
Sent from my GT-I9100 using XDA App
I have now tested the Bluetooth with a Logitech lazer Bluetooth mouse, in addition to the magic mouse and Microsoft mouse, with the same results. Does anyone else have this problem? Could the mouse HID been disabled by Samsung? or should I do a hardware warantee exchange?

I bought a cheap (8€) noname bluetooth mouse from amazon and it works perfectly on the Galaxy S2 on the stock rom, it also works on my Galaxy S running CM7.
Are you sure you have set your mouse to pairing mode?
(I had to press the connect button for 5 seconds)
I'm sure it's pairing. I press and hold connect on the mouse until it becomes visible to my galaxy s2. It ends up showing up as paired after I tap, but when I tap again, it only connects for a second (enough that the options for that device now show me HID) but it just drops immediately. But perhaps these mice with special buttons (like the Microsoft presentation mouse) and apple mice, and the Logitech mouse, are all beyond the scope of running on the phone.
I bought a super basic and cheap bluetooth mouse ($15 cdn) from amazon, it should arrive in 1-2 weeks. I'll follow up with this then. If the phone can't connect to that, I'm going to call Samsung and ask for a hardware exchange.
Also, I may be able to get my hands on a USB host cable, to see if i can get any mouse period working.
I really can't imagine it being faulty hardware though, considering all other Bluetooth functions work? or am I incorrect in assuming that?
So I decided to see what happens with a Bluetooth keyboard, and indeed I get the same result, connecting for a second then dropping.
I'm going to exchange my unit for a new one, hopefully that solves the issue. I'm getting paranoid that something is different with the white galaxy s2, can someone extinguish those fears for me?

Alright, follow up post. The new phone connects to mice/keyboards fine. It is current on 2.3.3. Could someone with an updated 2.3.5 s2 just confirm that the feature still works after update?
Edit: Ok, i let me phone upgrade from 2.3.3 to 2.3.5, and nothing can pair once again. Wow. Did Sammy really remove this functionality?
Final edit: Flash stock 2.3.6, and mouse will work again. So to recap, 2.3.3 good, 2.3.6 good, 2.3.5 bad
I have an Apple Mighty Mouse which work fine with my SGS1. It doesn't connect to SGS2. Same issue, the connection drops out after a second. My SGS2 is running on 2.3.6 Batista ROM with Siyah 2.3 kernel.
HID Bluetooth killed by 2.3.5 upgrade
Hi, I think I have a good picture of what has happened having trawlled the net looking for answers. In summary:
2.3.3 and 2.3.4 supported and worked with bluetooth HID devices (like my sandberg mini bluetooth keyboard).
2.3.5 as suggested by Samsung key's had issues with bluetooth from the start. It all looked good until you turned bluetooth on then it went into a FREEZE, BLACK SCREEN, LOCK SCREEN cycle with a 20-30 second window at best to try and turn bluetooth off once you realised it, repeating "ad infinitum".
Some folks found that a factory reset cured this. I got a replacement from Otrange UK after a lengthy discussion!
BUT however you may have fixed this is seems that any bluetooth HID device (Mouse, Keyboard) will not stay connected against 2.3.5. They pair ok, they even actually connect for a fraction of a second then bomb out again.
I just spoke to Orange UK Tech who in turn spoke to Samsung who said they were "Not aware" of the issue but would "Escalate a resolution" and get back to me. 2.3.6 is supposedly about to come out for Orange UK within "2 Months" and will contain a fix. Apparently. Looking at other stuff, 2.3.6 does appear to be the best hope.
They confirmed something though; 2.3.5 back to 2.3.3 / 2.3.4 is not supported/advised/safe so waiting for the new version is the only hope.
All this, so the lists won't bounce a'la APPLE and have a blue "bottom of list" flash instead... Ok, maybe there was some good stuff in the rom but it's kinda been overshadowed for me
Good luck out there and hold on to your hope!
I heard back from Samsung support today (Orange having referred my case).
They said that their 2.3.5 was new (erm, yes) and that it wasn't backwards compatible, and for any devices that no longer worked I would have to get that devices supplier to provide new software on that device.
They used a car kit as an example.
So I specifically asked "Are you saying you released an update without any warning, that would render all previosuly compatible bluetooth HID hardware incompatible?" And he answered that this was the case and that I would have to ask Sandberg to update my device so that it would connect to 2.3.5
Now, either he had absolutely no idea what he was talking about, or there is something very wrong at Samsung.
I have asked for him to confirm this to me in an email. (I intend to make use of this writen statement if it confirms the above conversation.)
Has anyone else ever heard anything so bizzarre?
I surely hope this can't be right!
So while I am waiting (and waiting, and waiting, LOL) for my Keyboard Dock, i remembered that I bought the USB adapter for the TF101 (fits into the proprietary charging/dock connector port, provides 1 USB port)
A soon as i attached it, I put a USB Mouse receiver/transmitter and it worked really well. The mouse tracked MUCH better than it even did on the TF101.
Until I went to the browser, and went to type a URL. The onscreen keyboard wouldn't come up (none of them, I have the two stock, plus Swiftkey X Tablet)
Stranger still I see the keyboard icon in the taskbar, and suddenly it hit me! The goofy thing thinks that the dock is attached! Sure enough as soon as I pulled the adpater out, the freaking keyboard popped right up.
None of this is going to cause any major issues, as I have a dock arriving tomorrow (I hope), but it's just another one of those overlooked items, and one that is SURE to get just about NO attention, LOL!
While I appreciate Asus wanting to get the flagship Tablet out there, and get ICS on it (has to be the #1 directive in tablet development at Asus at the moment, Asus needs to do a LOT more testing.
Also, and I have said this before, Asus needs to a) Try and get workable GPS functionality since it was they who put it in the tablet and b) Asus needs to repair the hardware on whatever percentage of tablets that get NO GPS signal at all. There is obviously a software component, since quite a few folks had, then lost SOME GPS function, but I have never had any, and I want it. Even if it is sub par, and works marginally, they advertised the spec, I wanted it, I bought it, I don't have it. End of story, as far as I am concerned.
Nobody has GPS working. Some may say they do but they do not know what they are talking about.
Also since the latest update, wifi location gets turned on automatically when a GPS app is trying to get a location.
Pretty much sweeping it under the carpet, it may work on those that don't know any better but for those that do know the difference it a pretty pathetic attempt.

Dude, Jen, seriously you are such a tool. Most everybody's GPS works. It is just not working well enough to navigate (which I agree is unacceptable). He is saying his won't see a single satellite in any condition. That is not working by definition. You insist on stating things as if they are fact when they may only apply to you. I can cold boot in airplane mode with nothing switching on my wifi and lock satellites in a windowless room in my house. I cannot however navigate. Those things are facts. If I were to continuously post that 'everyone can lock satellites with their prime and those who say they can't are just too stupid to know it' I'm guessing you would get annoyed at some point right? So please, if you have nothing constructive to say or you are too dense to know that just because something is happening to you doesn't necessarily mean it's happening exactly the same way to the whole community, then stfu. Please and thank you.

As an avid "emulator" user on the iPod Touch/iPhone 4, the first thing I did was install the Android varients and instantly found a problem where the A and B buttons would not be picked up as different buttons. This seems to be an issue amongst all types of emulators and I don't see why only OUR device experiences this.
After failing to find a way to get it to work, I mapped the A button to my Volume Down key.
Also, for some reason Bluetooth Wii motes DO NOT work with our device... why is that?
Anyways, if anyone knows a fix for this, please let us know!
Samsung insists on using a crippled Broadcom Bluetooth stack that doesn't play well with wiimotes or PS3 controllers.
CM7 firmwares often fix wiimotes but break Bluetooth audio (that is the case on the GSII and the Infuse for sure). CM7 for this device is quite a ways off... I'm thinking of pursuing it since it seems like we're close to the I9000 hardware-wise and we don't have to worry about RIL and call audio routing crap, but it'll be a while.

Ah okay, thanks for the update Entropy! Guess i'll just hold on until CM7 is eventually working for this device then!
For other people with this issue: The only real way of making emulators playable atm is mapping the A button to the Volume Down/Up hardware buttons. It is a bit awkward, but seems like the best way to do it and works once your used to it!

Hmm, can confirm that the Six Axis controllers MAY work. It says our device is supported when trying the app (I don't have a controller with me so I can't 100% try it).

I think the author of sixaxiscontroller may have found a workaround for the Broadcom stack suckage issues. I know sixaxiscontroller worked on my SGS2, which surprised me.
I'll try it tomorrow maybe - I do have a PS3 controller, but I have visitors this weekend.
SO after all the people worrying me I got mine today from Game Stop. Opened it up, rooted it, installed root keeper, upgraded to ICS and upgraded the camera. Wifi works fantastic at my work so far, and GPS locked me on me as soon as I upgraded Google Maps. It wasn't 100% perfect but it was accurate upto 20 meters.
I know this isnt a blog site, I just wanted to give some positive feedback after reading all of these nightmares forever.
Also, I am using wifi and my bluetooth mouse with no problems either.
Now we just need some love from ASUS so we can get some custom ROMs/Kernels
Told ya..lol. Glad to hear its working well for ya.

I do NOT want to be the one to rain on anybody's parade and insist that someone shouldn't love the product they just bought. Hell, I love my Prime as well, although I'm still debating whether to return the one I have with broken haptic feedback in hopes of finally getting one where at least every major component just functions at all.
That said, we do need to keep the issues clear that actually do exist. So:
1. If you have GPS completely turned off, Google Maps will still locate you to 20 meters via wifi-based location services. In fact, you might find that your GPS actually is turned off by default (I can't remember whether mine was on or off out of the box and following the ICS update). However, locking to 20 meters accuracy when connected to wifi has pretty much nothing to do with working or non-working GPS.
2. If you have another Bluetooth device to try other than a mouse, it would be interesting to see if you can stream more data (say, a BT headphone and streaming audio) and retain full wifi performance at the same time.
Nice to hear, I hope it stays (almost perfect).
Just to worry you some more:
Make sure you are streaming audio to a bluetooth from a video or something online. YOu want to make sure your BlueTooth is actually streaming something, and not simply turned on.
Check the edges of your screen. Make sure your screen is not lifting away from the back. This may or may not be a problem for your, but for my prime and some others, the glass appears to be raised above the Back Panel and can basically be pushed flush against it.
I love my prime, I love it. Except, I cannot update it cause I have no Serial Number. Even with my screen a little raised, and some light bleed on the right hand side, I would keep it if I could update the firmware. But I cannot, and have to take it back.

What Bluetooth device were you streaming to; presumably it was audio? While you were streaming to Bluetooth, did you do any SpeedTest runs? Would be interesting to see if you were able to maintain full Internet connectivity over wifi while streaming to Bluetooth...
my replacement ATP should be in today or tomorrow..i hope so.
They have one from a preorder that never picked up and the manager and I both agreed that it would be better not to open up one from the same "batch" but try fresh with this new batch..regardless if the units being released now are the same as before...(i doubt this from a production/shipping standpoint..otherwise if no new units were created...why the massive shortage upon release?)
the last question was more rhetorical.
Glad to see you have yours....I love mine other than what others are facing...screen separation, no GPS(none), WiFi is intermittently crappy...BT issue is intermittent..and something i haven't seen anyone talk about..i have a dead-zone right where the WLAN module seems to be. I've used both the developer screen visualizer and Multitouch Visualizer and have posted the video's confirming it "Skips" at the exact same spot and ONLY that spot.
Being an original transformer owner....I am in love with this one! IMO It is working great right out of the box smooth as butter.... I really don't know whats up with all these post about ICS being buggy,laggy,crashing.....?? This tablet is going to sell because its nice,fast,the screen is amazing and it's beat every other company off the line with cutting edge software & hardware... I'm not saying its perfect but it sure works for me.

this thing has so many problems that it's completely unusable! It times out its connection to my tablet after a few seconds. when I wake it back up it force closes whatever app I happen to be in. half the time it wont even wake up at all. It randomly repeats a typed letter, ad nauseum, during the brief intervals of "functionality."
I'm starting to get very skeptical about android. This is as bad as gtalk failing to send messages, which is another widespread fatal flaw that has gone completely unaddressed by Google.
The bluetooth implementation in android is BROKEN. SHATTERED. Extremely disappointing.
I've done a million searches seeking solutions to this problem and the internet is stone dumb on this issue. I want a workaround and I want it yesterday.
I'm using a Transformer tablet, but the same crappy issues are being had by my Xoom as well.

I'm sorry to hear that, I've used bluetooth mice, keyboards and stereo headsets from the TF101 (not sure about other androids) and they work a treat! They pair like a dream and allow you to rename them (which is great as my headsets name is KC302).
If you want a device with a poor bluetooth implementation I'd look at iOS. Does logitech assert Android as an OS it supports? Have you even spoken to them or are you just ranting? Bluetooth is a pretty solid standard these days, usually its when devices try to implement stuff beyond the standard that things get buggy.
Have you tried other roms? Kernels? (using the same devices)
I have in fact spoken to logitech and they want to send me a replacement (which wont help anyone.) The device has android printed on it's backside so it should work without a hint of trouble. Not.
I have rooted a few devices in my time, but not the transformer. Is it easy yet?

Or.. It might help? I agree though, doesn't sound all that promising.
I believe that depending on your firmware, its easier than turning it on.
The Razorclaw method requires installing an app from a link, then clicking one button. Make sure you have a compatible system first, but then it takes about 38.4 seconds from downloading to being rooted.
