Problem with bluez-simple-agent call in .bashrc or .bash_profile.

Hi,
  I am trying to automate bluetooth pairing at startup and I have put bluez-
simple-agent hci0 bdaddr in my bashrc and it always fails. When I run it 
manually it works i.e. I can pair. Why is that? 
It fails with "Connection error: In progress". I am not sure what it means. To  
replicate simply write "sudo bluez-simple-agent hci0 <bdaddr>".

Thanks.
