可视化工具一拖二tws+dongle一对一唯一快连配置

📎 原始文档：https://www.kdocs.cn/l/ctUPmgjtkU6t 可视化工具一拖二tws+dongle一对一唯一快连配置
以下修改即可实现dongle设备与耳机设备的一对一edr快连，dongle设备与耳机的默认快连是通过由蓝牙名生成快连码；修改为一对一快连后：耳机与dongle设备在首次连接还是通过蓝牙名生成的快连码做连接，在首次连接成功后，双方获取到各自的蓝牙mac地址，通过双方的mac地址生成唯一的蓝牙快连地址并保存至VM区，之后即是通过唯一快连地址去连接。
添加以下的一对一唯一快连配置后，如需添加修改清除双方一对一快连信息，则参考可视化工具一拖二tws+dongle-耳机与dongle之间实现通信控制.otl

【耳机端】

1.【syscfg_id.h】

#define     CFG_USER_EDR_QUICK_ADDR        3
#define     CFG_USER_DONGLE_ADDR        4

2.【earphone.c】

    u8 bt_addr[6];
    u8 local_addr[6];
    u8 edr_quick_addr[6];

        printf(">BT_STATUS_CONNECTED<\n");
        int ret = syscfg_read(CFG_USER_EDR_QUICK_ADDR, edr_quick_addr, 6);
        if(ret != sizeof(edr_quick_addr) || !strcmp(edr_quick_addr,0)){
            memcpy(bt_addr ,bt->args, 6);
            put_buf(bt_addr,6);
            if(btstack_get_dev_type_for_addr(bt_addr) == REMOTE_DEV_DONGLE_SPEAK){
                printf("CONNECT_DEV_IS_DONGLE\n");
                syscfg_read(CFG_BT_MAC_ADDR, local_addr, 6);
                put_buf(local_addr,6);
                for(u8 i=0; i<6; i++){
                    edr_quick_addr[i] = local_addr[i] + bt_addr[i];
                }
                put_buf(edr_quick_addr,6);
                if(edr_quick_addr){
                    syscfg_write(CFG_USER_DONGLE_ADDR, bt_addr, 6);
                    syscfg_write(CFG_USER_EDR_QUICK_ADDR, edr_quick_addr, 6);   
                }
            }
        }
        printf("-------------------------\n");

    int ret = syscfg_read(CFG_USER_EDR_QUICK_ADDR, edr_quick_addr, 6);
    if(ret == sizeof(edr_quick_addr) && strcmp(edr_quick_addr,0)){
        printf("----have_quick_addr----\n");
        for (u8 i = 0; i < 6; i++){
            crc += edr_quick_addr[i];
        }
    }
    printf(">>local_name:%s",bt_get_local_name());
    return 0xfd + crc;
}
#endif

【dongle端】

1.【syscfg_id.h-dongle程序】

#define     CFG_USER_EDR_QUICK_ADDR        2

2.【bt_status_event.c】

    u8 bt_addr[6];
    u8 local_addr[6];
    u8 edr_quick_addr[6];

        printf(">BT_STATUS_CONNECTED<\n");
        int ret = syscfg_read(CFG_USER_EDR_QUICK_ADDR, edr_quick_addr, 6);
        if(ret != sizeof(edr_quick_addr) || !strcmp(edr_quick_addr,0)){
            memcpy(bt_addr ,bt->args, 6);
            put_buf(bt_addr,6);
            syscfg_read(CFG_BT_MAC_ADDR, local_addr, 6);
            put_buf(local_addr,6);
            for(u8 i=0; i<6; i++){
                edr_quick_addr[i] = local_addr[i] + bt_addr[i];
            }
            put_buf(edr_quick_addr,6);
            if(edr_quick_addr){
                syscfg_write(CFG_USER_EDR_QUICK_ADDR, edr_quick_addr, 6);   
            }
            printf("-------------------------\n");
        }

3.【user_cfg.c】

u16 bt_get_quick_con_indicate()
{
    printf("<bt_get_quick_con_indicate>\n");
    u8 edr_quick_addr[6];
    u16 crc = 0;
    crc = CRC16(bt_get_local_name(), strlen(bt_get_local_name()));
    int ret = syscfg_read(CFG_USER_EDR_QUICK_ADDR, edr_quick_addr, 6);
    if(ret == sizeof(edr_quick_addr) && strcmp(edr_quick_addr,0)){
        printf("----have_quick_addr----\n");
        for (u8 i = 0; i < 6; i++){
            crc += edr_quick_addr[i];
        }
    }
    printf(">>local_name:%s",bt_get_local_name());
    return 0xfd + crc;
}

补充：耳机关机再开机概率不连接dongle只回连蓝牙；处理方法如下，耳机端添加TWS同步快连地址

#define TWS_FUNC_ID_ADDR_SYNC TWS_FUNC_ID('A', 'D', 'D', 'R')
u8 dongle_bt_addr[6];
void tws_sync_quick_deal(void){
    printf("tws_sync_quick_deal\n");
    u8 bt_addr[6];
    u8 local_addr[6];
    u8 edr_quick_addr[6];
    memcpy(bt_addr ,dongle_bt_addr, 6);
    syscfg_read(CFG_TWS_COMMON_ADDR, local_addr, 6);
    printf("user:put buf-local_addr:\n");
    put_buf(local_addr,6);
    for(u8 i=0; i<6; i++){
        edr_quick_addr[i] = local_addr[i] + bt_addr[i];
    }
    printf("user:put buf-edr_quick_addr:\n");
    put_buf(edr_quick_addr,6);
    if(edr_quick_addr){
        syscfg_write(CFG_USER_DONGLE_ADDR, bt_addr, 6);
        syscfg_write(CFG_USER_EDR_QUICK_ADDR, edr_quick_addr, 6);   
    }
}
static void bt_tws_quick_addr_sync(void *_data, u16 len, bool rx)
{
    if (rx) {
        u8 *data = (u8 *)_data;
        memcpy(dongle_bt_addr,data,6);
        sys_timeout_add(NULL,tws_sync_quick_deal,1000);
    }
}

REGISTER_TWS_FUNC_STUB(app_addr_sync_stub) = {
 .func_id = TWS_FUNC_ID_ADDR_SYNC, 
 .func = bt_tws_quick_addr_sync, 
};
void bt_tws_sync_addr_send(u8 *addr)
{
    printf("bt_tws_sync_addr_send\n");
    u8 data[6];
    memcpy(data,addr,6);
    tws_api_send_data_to_slave(data, 6, TWS_FUNC_ID_ADDR_SYNC); //发送数据给对耳
}
