好用的非商业免费蓝牙协议栈源码-btstack

github.com/btstack

1. windows上用msys2编译

cd port/window-winusb

make

2. ubuntu上直接编译

cd port/libusb/

make

注意：

hfp_ag_demo.exe

关掉l2cap加强重传

btstack_config.h

//#define ENABLE_L2CAP_ENHANCED_RETRANSMISSION_MOD

注意修改成需要连接的设备的地址

static const char * device_addr_string = "00:21:3C:AC:F7:38";

需要加pin的处理流程

packet_handler函数

                    case HCI_EVENT_PIN_CODE_REQUEST:
                            // inform about pin code request
                            printf("Pin code request - using '0000'\n");
                            hci_event_pin_code_request_get_bd_addr(event, addr);
                            gap_pin_code_response(addr, "0000");
                            break;

a2dp_source_demo.exe

关掉l2cap加强重传

btstack_config.h

//#define ENABLE_L2CAP_ENHANCED_RETRANSMISSION_MOD

修改目标地址

static const char * device_addr_string = "00:21:3C:AC:F7:38";
