开发板：LB52-DEV
开发分支：siflisdk-master, buletouch-master

在 main.c 中增加 mnt_init 完成 mtd 设备挂载文件系统的操作。

在 bf0_sibles_watchface.c 的函数 ble_watchface_event_handler 的 switch 中插入LOG_E日志。

    case BLE_GAP_UPDATE_CONN_PARAM_CNF:
    {
        ble_gap_update_conn_param_cnf_t *cnf = (ble_gap_update_conn_param_cnf_t *)data;
        if (cnf->status != 0)
        {
            LOG_I("update fail with %d", cnf->status);
            if (env->state != BLE_WATCHFACE_IDLE && env->update_repeat < MAX_UPDATE_REPEAT && env->update_state == BLE_WF_UPDATE_UPDATING)
            {
                LOG_I("update again due to collision %d", env->update_repeat);
                env->update_repeat++;
                env->update_state = BLE_WF_UPDATE_NONE;
                ble_watchface_check_connection();
            }
        }
        env->update_state = BLE_WF_UPDATE_NONE;
        break;
    }
    default:
        LOG_E("%s No supported case. event_id %d ", __func__, event_id);
        break;
    }
    return 0;
}

测试方式：

安卓手机使用，使用 SIFLI BLE ，在 BLE 连接成功后，选择 WATCHFACE → 表盘 ZIP → 选择 zip 文件。

预期结果：
手机端发送的文件会被保存到 /recv_file 目录下。

实际结果：
