[RFC v3 04/12] Bluetooth: Use connection parameters if any

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

 



This patch changes hci_connect_le() so it uses the connection
parameters specified for the certain device. If no parameters
were configured, we use the default values.
