Hi
Is there a tool/utility/option for enabling directed advertising?
Currently, it seems that the only options available through
bluetoothctl is undirected advertising. I can see that there is a
"type" field in the advertising section, but from browsing through the
source, it looks like the only supported options are "peripheral" and
"broadcast" (This can be seen in bluez/client/main.c). Is there an
option or another utility that enables this feature?
I am using BlueZ 5.50 on an Ubuntu machine running Linux 4.15.0-43 generic.
Thanks
Youssif

If I remember right, you can force the kernel to do directed advertising
by enabling the "advertising" mgmt setting (e.g. "btmgmt advertising on"),
and then issuing a connect on an L2CAP socket to your wanted destination
address. This was originally designed for testing purposes, so I'm not
sure how practical it's for anything else.
