Hi,
I am facing one issue with authentication during profile connection.
Two devices are there A and B which are paired.
From B I deleted the pairing of A.
Now from A I initiated a file transfer to B which failed during
authentication
since remote link key is not there.
Please see the hcidump logs.

But the same scenario with legacy pairing it is working fine. Pin code
request is coming
from the controller.

Is it controller issue or BlueZ has to take care this?
Please let me know your opinion.
Thanks,
