Hi, I am trying to figure out how to connect a phone by bluetooth thru terminal. I am just posting my progress here:
First! I Don't know how Ive got it working, but there must be something that I have done correctly to ensure the connection was successfully made. Secondly, this is going to be a mess and you are warned. Third, there is really not much info on this and quite a lot of them are specific issues rather than guides. I will make this as helpful and informative as I can:

Ensure that you have these installed:

Code:

Secondly use hcitool to descover devices:

Code:

root:# hcitool scan

Now use sdptool to show available services:

Code:

Pay special attention to the channel, rfcomm.
add

Code:

rfcomm0 {
	# Automatically bind the device at startup
 	bind yes;

	# Bluetooth address of the device
	device 50:56:63:A6:5E:06;

	# RFCOMM channel for the connection
	channel	16;

 	# Description of the connection
	comment "OBEX File Transfer";
}

to your /etc/bluetooth/rfcomm.conf and restart your bluetooth service.
now rfcomm should give an output similar to this:

Code:

server://home/ted
root:# rfcomm
rfcomm0: 50:56:63:A6:5E:06 channel 16 clean

if not, then this must have worked:

Code:

root:# rfcomm bind hci0 50:56:63:A6:5E:06 16 clean

Then rfcomm again.
Try restarting bluetooth service again.
Now use obexftp to access the device directories:

Code:

root:# obexftp -b 50:56:63:A6:5E:06 -l /

if you lack "OBEX File Transfer" or something like "OBEX FTP", ANND you are using an android fone, you could try downloading bluetooth file transfer by searching for "OBEX" in googleplay. And the service appears as:

Code:

Service Name: OBEX FTP
Service RecHandle: 0x10007
Service Class ID List:
  UUID 128: 00001106-0000-1000-8000-00805f9b34fb
Protocol Descriptor List:
  "L2CAP" (0x0100)
  "RFCOMM" (0x0003)
    Channel: 30
