I have a acer travelmate 5720 laptop that runs ubuntu 13.04. It has built in bluetooth. For what I can see is that Ubuntu did pick up the bluetooth and the necessary bluetooth drivers is installed. But I'm only able to send files from this laptop to bluetooth devices, but for some reason I can't do the same visa verso to the laptop, for example if I try to send a file from a blackberry 9360 it can't send, tells me failed to find service. It kicks out. I try to find more drivers to install, tried a few in ubuntu software center, but no success. I even uninstalled all bluetooth drivers and reinstalled it, but no success, it doesn't pick up any phone anymore. Please assist me.
