I'm working on Windows so it could be different (who knows) ?
Did you activate your peripheral encryption? What is your peripheral by the
way ?
In the issue, there is a link for the mailing exchange and there are some
things about android :
Also, it has been confirmed that it should be managed internally and that's
why we don't have any command to control the encryption behaviour. Thus, we
cannot really do a lot of things except going further in the source code or
trying to change command order or / and timing.
