耳机本地播放说明

📎 原始文档：https://www.kdocs.cn/l/cpvj3e36bBSX 耳机本地播放说明

1、彩屏仓耳机本地播放协议

增加两条指令
同步仓的经典蓝牙地址给耳机、耳机同步给对耳

void sys_smartstore_event_deal(struct sys_event *event)
{
    u8 *data = event->u.smartstore.args;
    u8 len = event->u.smartstore.data_len;
    log_info("sys_smartstore_event_handle");
...
 case CUSTOM_EDR_CONTRAL_CONN:
            log_info("CUSTOM_EDR_CONTRAL_CONN\n");
            custom_ctrle_edr_conn(data[0]);
            break;
        case CUSTOM_EDR_SYNC_INFO://仓的地址
            log_info("CUSTOM_EDR_CONTRAL_CONN\n");
            custom_ctrle_emitter_info(data,len);
            break;
....
}

耳机接收到仓的地址、同步给副耳同时清除配对信息

static void custom_ctrle_emitter_info(u8 *data, u16 len)
{
    log_info("%s[line:%d, len:%d]\n",__func__,__LINE__, len);
    memcpy(&emitter_info, data, len);
    // put_buf(emitter_info.emitter_addr, 6);
    sync_emitter_addr();
    sync_clear_last_info();
    clear_last_info();

    
}
//相关函数
static void remote_emitter_addr(u8 *data, u16 len)
u8* get_remote_emitter_addr(void)

对耳连接后同步仓的地址
相关函数

//发命令同步仓的地址
void sync_emitter_addr(void)  
//副耳接收到同步地址的回调函数
static void earphone_sync_sbox_setting_receive(void *_data, u16 len, bool rx)
{
...
case SYNC_CMD_EMITTER_ADDR:
            remote_emitter_addr(&data[1], len-1);
            break;
...
}

仓发命令连接耳机还是回连手机

void sys_smartstore_event_deal(struct sys_event *event)
{
    u8 *data = event->u.smartstore.args;
    u8 len = event->u.smartstore.data_len;
    log_info("sys_smartstore_event_handle");
...
 case CUSTOM_EDR_CONTRAL_CONN:        //控制耳机连接仓还是手机
            log_info("CUSTOM_EDR_CONTRAL_CONN\n");
            custom_ctrle_edr_conn(data[0]);
            break;
        case CUSTOM_EDR_SYNC_INFO:
            log_info("CUSTOM_EDR_CONTRAL_CONN\n");
            custom_ctrle_emitter_info(data,len);
            break;
....
}

void custom_ctrle_edr_conn(u8 cmd)
{
    u8 phone_mac[6];
    u8 mac_addr[6];
    
    u8 flag = 0;
    g_printf("%s[line:%d, cmd:%d]\n",__func__,__LINE__, cmd);
    switch (cmd)
    {
    case 1:         /* 如果连接手机先断开手机。然后处于可发现可连接状态 */

        delete_link_key(get_remote_emitter_addr(), 1);
            

        if ((BT_STATUS_CONNECTING == get_bt_connect_status()) ||

                user_send_cmd_prepare(USER_CTRL_DISCONNECTION_HCI, 0, NULL);
                get_current_poweron_memory_search_index(phone_mac);
                put_buf(phone_mac, 6);
        }else {
            bt_wait_phone_connect_control(1);
        }
        
        
        break;
    case 2:    /*发射器断开耳机、同时耳机清除仓的配对记录、如果之前连接过手机回连手机 */

        clear_last_info();
            // conn_emitter_addr[5] = ~conn_emitter_addr[5];
        sync_clear_last_info();

                

        flag = restore_remote_device_info_opt(mac_addr, 1, get_remote_dev_info_index());
        if(flag){
            printf("%s[line:%d] connected last mac\n",__func__,__LINE__);
            put_buf(mac_addr,6);
            memcpy(bt_user_priv_var.auto_connection_addr, mac_addr, 6);

            sys_timeout_add(NULL, sw_connect_last_device_from_vm, 1000);
        }
        
        // sys_timeout_add(NULL, sw_connect_last_device_from_vm, 8000);
        // conn_earphone_count = SWITCH_CONN_EARPHINE_COUNT;

        
    default:
        break;
    }
    
}
