How do you synchronise two Sony Rollys to dance/move in perfect synchonisation?

[301606]

Hello everyone,

I have two Sony Rollys SEP-30BT (black and white) which I want to organise to dance in synchronisation to music from my laptop.  I have updated both Rollys with the latest firmware files to work with bluetooth.  I have managed to pair each one to my bluetooth connection on my Asus S6f Laptop using Windows XP professional. Each Rolly will work fine ON ITS OWN using the bluetooth connection.  However when I try to turn both Rolly bluetooth links on (showns as headsets on the bluetooth file) the computer shows that only one can function as there is already one headset in operation and that two headsets cannot function at the same time.  Once the bluetooth link and the Rolly are paired, I can use any music player (ie Windows) and each Rolly will dance OK on its own.  I just don't know how to get the two paired to work together in synch using bluetooth.  Any help to overcome this would be very much appreciated.

Many thanks
