With Mate-Bluetooth (Mint 13, 14, 15) I only can connect to a BT mouse. After having installed blueman, I can connect to, but not browse on a smartphone - Error message:
failed to launch thunar [error 2]. No such file or directory.
You can enter an alternative browser in service settings
BT Icon > local services > Transfer / advanced:
command to start obex ftp browser
"%d is substituted with device address"
I suppose I have to replace thunar...
with something containing caja
