I've been having the most frustrating time getting OBEX to work from PC to Treo. I don't know if all Treo's like this, but when computers discover my Treo, it doesn't appear to have any services. So when I try to transfer a file from PC to Treo, I usually get an error that it doesn't have the service. Maybe after trying ten times I'll get it to work. It'll try to connect, the Treo will tell me it's connecting, but the computer just gives up. I have no problems sending from Treo to PC, I'm assuming because the Treo is initiating the transfer so the computer recognizes the service. Has anyone else had problems like this?
