btstack Struct Reference

#include <bt_hci_api.h>


Detailed Description

Represents one entity of a running stack (more possible) Keeps all data for one stack, like devices, buffers, states, ...

See also:
struct bt_hci_uart for definition of uart-transport.
Examples:

bt-lego/bt-lego.c, bt-remoteprog/demo-rprog.c, btstreamer/receiver/btreceiver.c, btstreamer/streamer/btstreamer.c, l2cap-cmd/l2cap-cmd.c, mhop_blink/mhop_blink.c, and rfcomm-cmd/rfcomm-cmd.c.

Field Documentation

struct bt_hci_pkt_acl* btstack::acl_cl_pkt

Pointer to the acl-buffer for connection-less data (local to the hci-layer)
