I cannot get my Universal Bluetooth Mobile Keyoard to work with my Sony Xperia Tablet Z. Sometimes it will ask for a code, and before I can enter it an error message pops up saying "cannot communicate with device". Other times I am able to enter the code with no errors, however, key presses are not registered at all on the tablet.
The most confusing part about this problem is that my Microsoft Wedge Mobile Keyboard works perfectly well with my tablet. And what's more, when the Wedge keyboard is connected, the bluetooth module in quick settings displays the Wedge kayboard name. While, when the Universal keyboard is connected, the bluetooth module in the quick settings doesn't seem to pick it up. I have also tried using both keyboards with my Nexus 5 running Android 5.0, and both keyboard work fine. Even more confusion!
It's important to note that while trying to connect either device, I've unpaired the other from the tablet. Basically, only one keyboard is paired with my tablet at any given instance. Therefore, this is not the issue.
I've heard that there was a bug in 4.3 Jellybean which caused some connectivity issues with bluetooth devices. My tablet is running a Cyanogenmod 4.4.4 Kit-Kat ROM, so that issue shouldn't be present here (at least, I think...)
Has anyone encountered this problem before, or have a solution?
