Hi,
I am trying to find the equivalent of using gatttool's --sec-level when
writing a python script to connect to an LE device over the d-bus API.
It seems like I have to set the Characteristic correctly. But I am missing
something obvious when looking through the doc/ api files.
Can someone point me to the right spot? Thanks!
Cheers,
Don

You can call Device1.Pair if you want to authenticate, once the LTK is
exchanged it will be used automatically in the next connections.

Hi Luiz,
Thanks for the response. I guess if the Pair() fails with Authentication
failure, that implies the device does not support it? I was playing with
this TI sensortag and wanted to double check how it was connecting.
So does the authentication get setup by the agent? And the Pair() to the
agent determines if the link will be encrypted?
Cheers,
Don
