Its a problem with the old Bluetooth driver for Android/Linux.. this was updated in December (Bluez 4.97) and now has that functionality (Actually I think they are up to Bluez 4.99 now
).. but unfortunately Sony don't seem interested to give it to us in a update.
Either install Cyanogen Mod 7 (it has the new Bluez stack included) or wait for the official ICS release from Sony (this should hopefully have the new Bluez stack included.. fingers crossed
) I have been waiting for this for my Xperia phones for 2 years now.. I installed CM7 on my Mini and it works sweet with the MW600.. just dont want to install it on my Neo because I use the HDMI functions all the time and CM7 doesn't support HDMI.
unless someone can port the new Bluetooth stacks to a Stock Rom?? any takers? huh?
Xperia Neo - NightElf Kernel - Stock ROM
X10mini - nAa10 Kernel - MiniCM7-2.1.8
