需要增加解析命令回调

static void identification_cmd_handler(u16 acl_hdl, u8 arg_num, int *argv)
{
    u8 i, j;
    int trans_role = argv[0];
    u8 *data = (u8 *)argv[1];
    int len = argv[2];
    if (trans_role == CONNECTED_SYNC_CALL_RX) {
        for (i = 0; i < CIG_MAX_NUMS; i++) {
            for (j = 0; j < CIG_MAX_CIS_NUMS; j++) {
                if (app_cig_conn_info[i].cis_conn_info[j].acl_hdl == acl_hdl) {
                    put_buf(data, len);
                    break;
                }
            }
        }
    }
    /* 由于转发流程中申请了内存，因此执行完毕后必须释放 */
    if (data) {
        free(data);
    }
}

CONN_DATA_TRANS_STUB_REGISTER(identification_cmd) = {
    .uuid = CONNECTED_UCMD_SYNC_FUNC_ID,
    .task_name = "app_core",
    .func = identification_cmd_handler,
};

#define CONNECTED_UCMD_SYNC_FUNC_ID           CIG_FUNC_ID('U', 'C', 'M', 'D')

2. 发送命令demo，自行根据主从机角色调用不同接口去收发命令

    case   KEY_MASTER_SEND_TO_SLAVE :
        u_data++;   
        printf(" KEY_MASTER_SEND_TO_SLAVE u_data is %d \n", u_data);
        connected_send_data_to_sibling(CONNECTED_UCMD_SYNC_FUNC_ID, &u_data, sizeof(u_data), CONNECTED_DEVICE_IDENTIFICATION_L);
        break;
    case   KEY_SLAVE_SEND_TO_MASTER :
        u_data++;   
        printf(" KEY_SLAVE_SEND_TO_MASTER u_data is %d \n", u_data);
        connected_send_data_to_sibling(CONNECTED_UCMD_SYNC_FUNC_ID, &u_data, sizeof(u_data), CONNECTED_DEVICE_IDENTIFICATION_M);
        break;
