The dongle installs fine and works perfectly with all my older phones but not with my Xperia S running Android 4.1.2.
Basically, if I install the automatic windows driver, and pair with the phone, windows complains about no drivers for the device, and I can't do anything with it.
If I install the supplied software (CSR Harmony wireless software stack) I can pair and the Xperia S is installed properly, the various audio services work (I can stream music to PC using BT), but I still can't send or receive files, either from PC to Phone or from Phone to PC.
The connection times out after a second and gives me a connectivity error. It's like the phone refuses to connect to the PC, both when transferring and receiving.
I don't know if the phone is the problem, it seems to not work only when doing file transfers with PC, if I try to transfer files to other phones or to my mac (which has built in BT) it works fine.
Is there any way to fix this issue? Any way to troubleshoot this issue to tell if the problem comes from the phone or the dongle?
Searching with google I can't find any solution, I just get lost into a sea of bluetooth problems which have nothing to do with what I'm experiencing.
By the way, using Airdroid instead of BT is not a fix.
