I have a treo 650 and a new laptop with Vista. I have a belkin bluetooth adaptor that works great with my computer. I have no problems hotsyncing using bluetooth. But I try to connect with pdanet via bluetooth I get error messages code=666,773,780. Pdanet is on the same port (com5) as my hotsync but it never connects. My bluetooth icon in my bottom right hand corner of the screen says I successfully connected. Any help or suggestion please.
