struct sockaddr_bt { uint8_t bt_len; sa_family_t bt_family; bdaddr_t bt_bdaddr; uint16_t bt_psm; uint8_t bt_channel; };
The local address used by the socket can be set with bind(2).
The bt_psm and bt_channel fields in the sockaddr_bt structure are ignored by HCI protocol code and should be set to zero.
HCI socket options:
HCI sysctl(8) controls:
L2CAP socket options:
Link mode settings will be applied to the baseband link during L2CAP connection establishment. If the L2CAP connection is already established, EINPROGRESS may be returned, and it is not possible to guarantee that data already queued (from either end) will not be delivered. If the mode change fails, the L2CAP connection will be aborted.
L2CAP sysctl(8) controls:
RFCOMM socket options:
Link mode settings will be applied to the baseband link during RFCOMM connection establishment. If the RFCOMM connection is already established, EINPROGRESS may be returned, and it is not possible to guarantee that data already queued (from either end) will not be delivered. If the mode change fails, the RFCOMM connection will be aborted.
