bluetoothkeyboard
The Bluetooth keyboard on Asus T300 Chi has been disconnected and I can't seem to get it to connect (pair) again. It's asking for a PIN that should be showing so you can enter it on the keyboard to complete the pairing process but it never shows the PIN. I have tried:
Rebooting the system
Tried Random PINs that matched on the tablet and the keyboard.
Uninstalled and installed the Bluetooth drivers.
0000
Searched on Asus forums but no with no luck.
It should be an overlapping use of same frequencies by different equipment
One possibility could be wifi, take a look at http://en.wikipedia.org/wiki/List_of_WLAN_channels#2.4.C2.A0GHz_.28802.11b.2Fg.2Fn.29 and compare then with
http://www.newlogic.com/products/Bluetooth-Tutorial-2001.pdf the bluetooth adapter operate at a frequency spectrum in the 2.402 GHz to 2.480 GHz range.
You should use CommView for WiFi (Windows) or wifi analyzer (Android) to make sure that your network isn't causing that random disconnections, proceed disabling your wifi (physically turn it off) and re connect, if this solves the problem, try changing your wifi channel configurations other good tries could be turning off others BT devices.
By the way, the BT should be able to alternate channels and avoid interferences, but I have issues with a router in an train station that causes this kinda of disconnections, until I managed a way to wait the train in a point of the platform that is distant of that router.
I tried pairing the device on Ubuntu 12.04. Upon clicking on "Add a new device" it shows the following screen; the "PIN Options" button shows a dialog box that allow me to either select some sort of PIN auto configuration or insert a PIN manually.
The same dialog box states that many devices have their default PINs set as 1111, 1234 or 0000; the latter more common for devices such as microphones, mice and GPS.
I have entered 0000 on my device and it paired.
