Subject: Query regarding bneptest tool

Hi All,

I am testing BlueZ bnep test tool (tools/bneptest) using PTS 6.1.0.
The BNEP client test cases are not passing in BT_IO_SEC_MEDIUM security
level.
My PTS PICS and PIXIT are same as android/pixit-bnep.txt,
android/pics-bnep.txt.
Whereas when the security level is BT_IO_SEC_LOW, it is passing.
If it is a valid fix, then I will send a patch for the same.
This is tested in Linux, not sure about android.

diff --git a/tools/bneptest.c b/tools/bneptest.c
index 98ee9b1..fccecd2 100644

Sorry. The issue is in controller. When I used PTS dongle, there are no issues, working perfectly.
All test cases are passing.
Thanks.

The passkey looks correct:

> HCI Event: User Confirmation Request (0x33) plen 10 [hci0] 128.242120
Address: 00:1B:DC:07:33:4E (Vencer Co., Ltd.)
Passkey: 564246

But we never confirm it then PTS probably times out waiting for it. If
you are getting release that probably means the agent is no longer
registered, but then I wonder why it received the RequestConfirmation.

30 seconds has passed then probably PTS gives up.

It might be related to pairing then, do you have any agent registered
in the system? Check the HCI logs with btmon, it should tell us what
is happening.
