Hi Maintainers,
This patch series defines the new two-call MGMT interface in userspace
for adding advertising instances. Bluez will detect if kernel supports
the new MGMT commands, and use them if so. Each new advertising instance
will be configured by a MGMT call to set advertising parameters,
followed by a MGMT call to set advertising data. The new data pipeline
is meant to be unnoticeable from the clients' perspective, with the
exception of new intervals and tx power support, and new exposed
advertising manager properties.
All changes have been tested on hatch (extended advertising) and kukui
(no extended advertising) chromebooks with manual testing verifying
correctness of parameters/data in btmon traces, and our automated test
suite of 25 single- and multi-advertising usage scenarios.
V2 of the series puts documentation at the front as requested.
Thank you in advance for your review!
Daniel Winkler
