Root Mini Bluetooth Keyboards - How to get one to work

There are many Mini Bluetooth Keyboards for sale from eBay, Amazon, and others. Typically priced between $10 and $20, they have a spotty reputation at best. Most of the negative things said about these keyboard is that they don't work very well with Android. There are limitations in Android's bluetooth abilities, these are not the fault of this product. To function you need Android 2.3. You may have to un pair and re-pair your keyboard from time to time. The keyboard is a HID device (as opposed to SSP) so you'll need a driver for it to work properly. There are a few options in the Android Market for this, but most of them are paid apps and you shouldn't need to buy the software to make your new hardware work. I did, however, find a free solution. The app Bluekeyboard JP does the job nicely, and is free. One thing to note, you'll need to set the keyboard type as Apple Wireless Keyboard, not qwerty. The reason for this is none of the function keys work on the qwerty setting, so no punctuation. Set as the Apple, every key works. One caveat to this work around, while the function keys do work, they are mapped slightly differently than they're labeled so some trial and error may be needed to get the hang of it. I give this product three stars because of the unnecessarily convoluted setup and lack of driver software included, but great battery life and ease of use (once set up). This is a good option to add hardware controls to any touchscreen only device. Also works great as a game controller too!

I picked mine up from Amazon.
 
Because it was requested, and this information is useful to non rooted users as well. None of the requirements for the product list that, I had to figure it out myself. If a non rooted user were to purchase this, they would be stuck wondering why it won't work when the package says it will.
 
Thorsten makes a very good point brotherswing.
For this thread to truly work as you intended, the title would have to reflect that the bluetooth keyboards only works on 2.3 and up.
 
I did find in my research that it won't work on sense roms. I know that has nothing to do with the OV, but owners of other handsets do stumble in here, and its good information. The deal there is HTC nerfed HID support for bluetooth on all of their devices.
 
Stock LGOV (running Android 2.2.1) + BlueKeyboard JP + Motorola Bluetooth Wireless Keyboard (a HID keyboard made especially for Android) does not work.

The keyboard pairs just fine (no surprise, you get that without any apps or drivers) and is recognized as

PI didn't test it myself, I was working from several different threads at once (mostly XDA, and a couple of Japanese sites in Google Translate) and took the information in good faith. As it is, its a hack at best, so I suppose I shouldn't have expected to much. What I do know is bluetooth devices use two different protocols to communicate, SSP and HID. Froyo does SSP all day long, no problem. It has issues (heh) with HID, and results are mixed at best. I did not verify the accuracy of this info, but quite a bit came from code.google.
Well, we'll call this real world data, and I admit, I was wrong. :oAndy, would you please move this to All Things Root?
I'll edit the title and related details this evening.
 
Hi all I have the latest Backside-IHO ROM installed on my Optimus V and still I can use the mini Bluetooth keyboard. It connects fine but when I tried to type nothing happens. I installed the bluekeyboard JP and it connects then disconnects. What other program can be used with the Bluetooth keyboard?
 
It's a problem with the new kernel in the ROM. It's actually not a problem as such, but my little hack doesn't seem to work anymore. I'm trying to find another (more elegant) solution. Stay tuned, I'll post updates as I figure things out.
