Bluetooth: Use lower timeout for LE auto-connections

When we establish connections as a consequence of receiving an
advertising report it makes no sense to wait the normal 20 second LE
connection timeout. This patch modifies the hci_connect_le function to
take an extra timeout value and uses a lower 2 second timeout for the
auto-connection case. This timeout is intentionally chosen to be just a
bit higher than the 1.28 second timeout that High Duty Cycle Advertising
uses.

Bluetooth: Clear HCI_RAW flag when controller becomes configured

When an unconfigured controllers reaches the configured state, it is
important to change the HCI_RAW flag. It indicates to userspace that
the controller is fully operational.

External configuration allows to bring the controller back into an
unconfigured state. In that case make sure HCI_RAW flag is set again.

9 years agoBluetooth: Add support for changing the public device address
Marcel Holtmann [Sun, 6 Jul 2014 10:11:15 +0000 (12:11 +0200)]
Bluetooth: Add support for changing the public device address

This adds support for changing the public device address. This feature
is required by controllers that do not provide a public address and
have HCI_QUIRK_INVALID_BDADDR set.

Even if a controller has a public device address, this is useful when
an embedded system wants to use its own value. As long as the driver
provides the set_bdaddr callback, this allows changing the device
address before powering on the controller.
