I just bought a Latte Tab2 tablet. So far I have been impressed with performance for the price, and rooting was simple. My main issue is I got this thing for to write with while on the road with a BT keyboard, but for some reason the blue tooth on the tablet stops working. To explain further:
Tablet will pair with keyboard (keyboard works on my 4.1.2 phone and ios devices no problem)
I can open up any text app and type, but the moment I stop typing (sending input through BT) it's like BT shuts down, although it says the keyboard is still connected. If I tap "search for bt devices" I can immediately start using the keyboard again, until I pause for more than a few seconds, when the tablet stops "looking at" the keyboard.
If I turn off my keyboard, the tablet doesn't recognize that it shuts off unless I hit the "search for bt devices" again.
It's like the tablet's BT just sort of goes to sleep if it doesn't have constant input from the keyboard.
My other issue is that I can't write anything to the external SD card, only internal, even with link2sd installed, but that can wait for another day! I need BT help!
Thanks!

I purchased a Targus Bluetooth Wireless Keyboard (has the Android logo and claims compatibility). It paired and connected without any issues and works with all of the apps that I have tried (gmail, text client, Docs To Go, etc.). It also works with Webtop apps, including Citrix (which is why I needed the keyboard).
The problem is that when the keyboard is connected, Webtop will randomly crash and re-start (Motorola logo appears and Webtop re-initializes). I have tried this many times, with and without the keyboard and it is definitely related to having the keyboard connected. Sometimes it will crash right away, while other times it will last 2 or 3 mins. It always fails with 5 mins.
I have tried it using 4G (mine will go to 3G at times due to my area) only (WIFI off) and did not effect the crashing (though WIFI does seem to have conflicts with Bluetooth being on).
Has anyone successfully had a Bluetooth keyboard work? Is there a setting I am missing?
Any help would be much appreciated.
I am still having this problem. Has anyone gotten this to work?
I am using a logitech bluetooth keyboard for android 3.0+ tablets, a bit of a PITA to get it paired, but has been working flawlessly for 2 days now.

Not saying its the only one that will work, I'm sure there are more.
Just a heads up for anyone that gets this keyboard, pairing procedure for the razr is...
1. turn on the keyboard
2. hit the "connect" button on the bottom.
3. find the keyboard in the bluetooth menu on your phone and touch to pair to it.
4. When prompted for the password type "0000" in the popup on your razr.
5. On the bluetooth keyboard type "0000" and press enter. Its VERY important to press enter.
6 your keyboard is paired!
I've used an iPhone4 BT keyboard on my ATRIX....and on RAZR works, too.
Well it turns out the Motorola Wireless keyboard works flawlessly with Webtop as well. Guess I chose the wrong keyboard for my first try.
I am now using the Motoroal Wireless keyboard ... bought through Amazon.
Thanks for all of the posts!!
I just bought a Logitech bluetooth audio adapter (Model 980-000540) and am having a lot of trouble getting my Asus Transformer Prime to pair with it.
I've got the gold TF201, 32GB, all software up to date. I've gotten it to pair a couple times reliably, but the other 20 times I've tried pairing it works like this:
1) Press the button on the Logitech that puts it into discovery mode. The light on the unit starts flashing green to indicate it is announcing itself.
2) In the Prime settings, I have Bluetooth enabled, and then search for devices.
3) The Logitech unit shows up in the "Available Devices" list pretty quickly. Sometimes I see (what appears to be) a MAC address, sometimes it shows up as "(A9)Logitech Adapter".
4) When I click on the Logitech item in the list, it goes gray and says "Pairing" underneath it.
5) Most of the time, it the moves to the section above, to indicate that it has paired.
6) Immediately the green light changes to red on the Logitech, indicating it has lost pairing.
7) Shortly afterwards, the Logitech item goes back into the "Available devices" section.
8) If I try to pair now, with the Logitech no longer in discovery mode, the Prime will show a dialog that says "Couldn't pair with (A9)Logitech Adapter because of an incorrect PIN or passkey." The only option is OK, and there is no ability to set the PIN.
This happens 19 out of 20 times, but it's locked on a couple times and seems totally solid and reliable after that. It's just the pairing process which seems unbelievably fragile.
To my surprise, my Samsung Galaxy Nexus (LTE) has no trouble pairing with it at all. It paired the first try, and now whenever I turn Bluetooth back on it immediately syncs with the Logitech with no hassle at all. Rock solid.
I've tried various tricks, but none seem to work:
- Put the tablet into Bluetooth-broadcast-visible mode at the same time.
- Turning bluetooth off and then back on, etc.
Has anyone else had trouble with Logitech bluetooth speaker adapters too? Or does anyone have any tricks or apps that can coax the Transformer Prime into pairing more reliably?
Thanks for any help,
Jim
I had a very similar problem last week trying to pair a LG headset with the prime, connected with phone perfect, and but likewise when trying to connect also to prime second got the lost connection, incorrect pass/pin etc etc.
I solved it by connecting bluetooth headset to phone, then under phones bluetooth settings press and hold device name to bring up a menu, and select options. Then unchecked the Media option/box. I then tried to connect the device to prime and it worked flawlessly. Since then I haven't had an issue and can even switch between the phone/prime & bluetooth device with no issues.
Hope above helps and you get it sorted.
Try this app. It may help if nothing else does.
Bluetooth Address Finder - Market
Not sure if the Prime or your Logitec gives you the option to input the BT address or not. I've not had any problems pairing or connecting to any of my BT devices.
This is seriously getting annoying. Recently, i bought a Rapoo Bluetooth Keyboard E6300 as i thought it would be convenient for me to type and take notes in class with my XS. However, when i tried pairing, it paired perfectly for the first time and all the media buttons worked perfectly too. However, 4 or 5 mins later, it disconnects and is REALLY HARD to reconnect. It would automatically reconnect but only when the bluetooth feels like it. Is the problem with the phone or the keyboard?
I've tried external apps to try solving the problem like "BlueKeyboardJP" and "Bluetooth Keyboard Easyconnect". These apps help with a faster pairing at first but then the connection still gets disconnected and reconnecting also takes time. And also reconnecting needs to be done manually.
Why won't my bluetooth keyboard connect to my XS properly and STAY CONNECTED until i turn bluetooth off?!
Please HELP!
I'm finding the pairing of the Folio Keyboard with my Nexus 9 to be problematic. I'm not sure if this is because there's an issue with NFC on either device or I'm just doing it wrong.
Pairing the keyboard using only bluetooth works but needs to be triggered by selecting the already paired with keyboard in bluetooth settings and can take 10s of seconds before it is connected. I expected that the keyboard would connect as soon as it came in range of the NFC chip, but it doesn't. I think NFC at least partially works as the keyboard is detected by the tablet as a trusted device via NFC. When I follow the directions to pair the keyboard via NFC by placing the tablet on it in the right manner it does not pair though I hear a tone when the doing it, that doesn't happen when I change the orientation of the tablet. From this I conclude that the NFC hardware works but something in my use of it, the configuration of the tablet or a system bug is stopping it working properly.
1) Is it a reasonable expectation that I can be expect once pairing has been completed that placing the tablet on the keyboard will be recognised by NFC without having to lay the tablet in the manner described in keyboard documentation?
2) Assuming the desired outcome as described above is possible will this trigger the tablet to turn on bluetooth (if it is turned off) or is it necessry for bluetooth to be either manually turned on, left on or find some other mechanism that triggers bluetooth to be turned on in order to connect the keyboard?
3) Is it a reasonable expectation that keyboard and tablet to be quickly connected (in a second or so) via bluetooth?
1. Once they're paired. They're paired, no need for nfc.
2. It will not turn on bluetooth automatically. Just leave bluetooth on at all times.
3. Mine connects pretty quickly once I learned the proper method to do it, that being with bluetooth on, slide the camera portion of the table slowly over the portion of the folio just above the number row. And visa versa to unpair.
The only annoying thing about this keyboard folio is the fact that I need to turn back on the "hardware input" to either see the on screen keyboard when not using the tablet, and turn off the onscreen keyboard when using the folio keyboard. I wish it did that automatically. I'm either missing something, or need to figure out a way to do that with tasker, via touch imputs or something.
Yeah, once you connect via bluetooth, NFC is no longer needed.
The frustration I am experiencing is that once the keyboard is paired and connected...if I turn bluetooth off or it disconnects, it won't automatically reconnect the next time BT is turned on. Am I missing something here? It's like the keyboard is asleep and the nexus can't find it to connect to.

I generally just touch an input then hit a button on the folio keyboard. In about 1 or 2 seconds the letter will show up and the on screen keyboard will disappear. From there I just type normally.
I was using my wireless Logitech desktop set but I noticed some lag after not using it for some seconds. When I keep using the mouse or keyboard there is no problem and everything works fine. But when I stop typing or stop mousing for longer than three seconds, the tablet doesn't recognize any input anymore. When I move the mouse or use the keyboard, nothing happens, but after two seconds any input is recognized again.
So I have to keep typing or else I have to wait some seconds to let the tablet recognize any input. This is unworkable.
I tested it with two desktop sets with two different Unifying receivers. When I use a corded mouse or keyboard, everything's fine. It seems to me that there is some sort of logitech standby mode which the tablet can't handle or something.
What can I do abaout this?
Added logcat of connecting usb, a freeze moment, and the disconnection. But I see nothing wrong there...

I bought an other Logitech Wireless mouse (standard receiver, no Unify) and that one works perfectly. So it looks like it has something to do with Unify, not wireless in particular.
Anyone?!
The Shield tablet has the same issue:

Maybe it has something to do with the Tegra K1?

It is really annoying. My Shield Tablet is fantastic, except for this issue with the keyboard/mouse. Sad panda.

And no solutions yet. Maybe a different kernel will work, but I like to keep my N9 stock (the first months hehehe)
Any solution?
Has there been any solution to this issue yet? I too am having the same problem.
Work Around
I have a work around that seems to fix this issue. For this to work you will need to be root. Also note that this solution will cause all USB devices to remain on at all times and will not survive a reboot. My experience is mostly with linux and very little with android. I expect someone should be able to modify the following script fairly easily for a more permanent solution.
Open your favorite terminal emulator and type the following four commands pressing enter after each:
su
for i in /sys/bus/usb/devices/*/power/control;
do echo on > $i;
done
This script toggles the power control setting for all usb devices from the auto state to always on. Hope this helps!
I have a slight lag with my logitech controller through USB OTG. It's just a split second lag, but it's there right from when you plug it in. Makes it unusable for gaming. No issues whatsoever with my Logitech bluetooth keyboard however.
