LS3578 connectivity issue



has anybody seen LS3578 losing connectivity to VC5090 for a couple of seconds although within range and for no apparent reason? LS and VC are on latest builds and VC is on Max performance mode (i.e. never sleeps). LS is connected to VC through SPP. The issue appears randomly (not easy to reproduce)and the connection is restored almost immediately. We have seen this in two cases with LS3578, one with BT connection to VC5090 and one in BT connection with cradle. We have lost one deal with a customer because of this problem, against LXE. Thanks in advance,
