After the official rom S5830XWKS9_S5830OXXKS2_FOP it's no longer possible to connect any bluetooth device that report their Class of Device (CoD) code as 0x00 (zero). Currently there is a bug in the Broadcom bluetooth stack that, for some reason, intentionally skips discovery of all such devices.
I saw in various forums that many people is worried about that and no one solved this problem.
Imbawind , is there any way to solve this problem? Maybe replacing the bluetooth system files of your rom by the files from the rom S5830XWKS9_S5830OXXKS2_FOP...
