[RFC v3 08/12] Bluetooth: Re-enable background scan in case of error

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since we temporarily stop the background scanning in favor of
connection, we should re-enable it in case something goes wrong
with connection establishment. So this patch adds a hci_update_
background_scan() call in create_le_conn_complete() and hci_le_
conn_complete_evt() error flow.
