Hi,
what is Your BlueZ version? Also on some (older) Android devices
(ROMs) there is no SSP, (not sure whether agent version matters eg
bluetooth-applet).
In other cases SSP should be used by default.

Start by upgrading BlueZ :P ... to some reasonable new version ...
4.93 is the most current one.

I am running BlueZ 4.93, and have noticed when attempting to connect, BlueZ 
connects and closes the connection the first time.

plugins/hciops.c:conn_complete() status 0x00
src/adapter.c:adapter_get_device() <dev addr>
plugins/hciops.c:remote_features_information() hci0 status 0
plugins/hciops.c:disconn_complete() handle 38 status 0x00
src/event.c:btd_event_disconn_complete()
src/adapter.c:adapter_remove_connection()


Fortunately for me, I control my device's firmware, and instead of giving 
up, just retry the connection a few seconds later (using the CSR stack).

plugins/hciops.c:conn_complete() status 0x00
src/adapter.c:adapter_get_device() <dev addr>
plugins/hciops.c:remote_features_information() hci0 status 0
plugins/hciops.c:io_capa_response() hci0 IO capability response from <dev 
addr>
plugins/hciops.c:io_capa_request() hci0 IO capability request for <dev addr>
plugins/hciops.c:get_auth_info() hci0 dba <dev addr>
plugins/hciops.c:get_io_cap() initial authentication requirement is 0x04
plugins/hciops.c:get_io_cap() final authentication requirement is 0x04
plugins/hciops.c:user_confirm_request() hci0
plugins/hciops.c:user_confirm_request() auto accept of confirmation
plugins/hciops.c:hciops_confirm_reply() hci0 dba <dev addr> success 1
plugins/hciops.c:simple_pairing_complete() hci0 status 0
src/event.c:btd_event_simple_pairing_complete() status=00

In my device the HCI code returned is 19 (0x13: Remote User Terminated 
Connection)

Also, note that when connecting with my BlackBerry Torch and my Windows XP, 
Windows 7 and Windows 2008r2 laptops (all using the Toshiba stack), this 
disconnection does not happen.  Pairing works just fine, albeit Legacy 
pairing (requiring PIN entry at the laptop).

Hope this helps.

FWIW: Bluez/Dev box is Fedora14, AMD x86 Sempron, running hand-built BlueZ 
4.93 (none of the stuff from the Fed14 package).  USB Class 1 BT 2.1 Dongle 
from Cirago, but based on CSR BC04 chip.
