Hi all,
This patch set takes in consideration Marcel's comments from previous revirew as
well as introduces privacy feature support to LE auto connection mechanism.
Below follows a summary to help the review process:
* Patches from 1-10 are pretty much the same from previous version
(exception to Patch 8). They introduce the LE auto connection
infrastructure and auto connnection options.
* Patch 8 modifies hci_conn_params_add() and hci_conn_params_del() so they
also add/delete pending LE connections according to the auto_connect
option. This way, background scan is automatically triggered/untriggered
when connection parameters are added/removed. This feature was requested
in "[RFC v10 10/10] Bluetooth: Add le_auto_conn file on debugfs" review.
* Patches 11-12 add resolvable addresses support for LE auto connection
mechanism.
* Patches 14-15 change set_scan_params() so it restart background scan when
new scanning parameters are set. This allows us to update scanning
parameters on the fly.
This patch set don't filter duplicates on background scanning. The "time to
time re-enable scan" approach suggested in previous review might not be good
enough. Depending on how many time we wait to restart background scan, some
low latency reconnection profiles, such as HID over GATT, can become
impractical.
Moreover, just fine-tuning the scan parameters might be good enough. With
patches 14-15, we can easily change background scan parameters and do lots
experiments.
Finally, if enabling filter duplicates is really the way to go, I can write a
small patch set improving the background scan routine.
BR,
Andre
