Hi all,
I have two android phones, when i connect two phones using
bluetooth it generates passkey and displays it for our conformation,
once we conform, pairing takes place , i was able to transmit and
receive data via bluetooth. i want to change the pairing process to
"just works" of SSP. so that the phones connect automatically without
MITM protection. how to change the pairing mode of SSP from numerical
comparison

Android is based on linux, I think Majority of Android phones uses only
Bluez as the bluetooth stack, Can you please mention what are the other
Bluetooth stack used in majority of Android phones. So that many of us
like me can known about that.

Majority of Android phones don't use Bluez as the Bluetooth stack.
If your phone uses Bluez, what Johan said will work.
If not, post to the Android mailing lists as this is dedicated to Bluez.

There are two ways how to do this:
1. Make sure neither side requires MITM by setting the security level
for each socket to low.
2. Set NoInputNoOutput as the IO capability for the agent on one or both
sides (you can override the Android agents capability e.g. by doing your
own CreatePairedDevice D-Bus method call).
