[RFC 1/7] Bluetooth: Add new connection states

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

 



This patch adds two new connection states which will be used by
hci_conn to establish LE connections.

BT_SCAN state means the controller is scanning for LE devices. Once
the target device is found, the connection goes to BT_DEV_FOUND
state, and then to BT_CONNECT state.
