Bluetooth data buffer API.
struct net_buf * bt_hci_evt_create(uint8_t evt, uint8_t len)
Allocate an HCI event buffer.
int bt_hci_driver_register(const struct bt_hci_driver *drv)
Register a new HCI driver to the Bluetooth stack.
struct net_buf * bt_hci_cmd_complete_create(uint16_t op, uint8_t plen)
Allocate an HCI Command Complete event buffer.
bt_hci_driver_bus
Possible values for the 'bus' member of the bt_hci_driver struct.
Definition hci_driver.h:59
struct net_buf * bt_hci_cmd_status_create(uint16_t op, uint8_t status)
Allocate an HCI Command Status event buffer.
int bt_recv(struct net_buf *buf)
Receive data from the controller/HCI driver.
int bt_hci_transport_setup(const struct device *dev)
Setup the HCI transport, which usually means to reset the Bluetooth IC.
int bt_hci_transport_teardown(const struct device *dev)
Teardown the HCI transport.
