PSDK V3.4 在 M300 OSDK模式下重启容易失败

使用配置如下：PSDK V3.4 ， M300, 通过串口和ACM连接，等效于以前的OSDK
 
log如下，在不重启板载电脑的情况下，重启PSDK程序，3次中就会有一次 Try identify UART0，并最终 Core init error. 225。 
  1. 请问是什么问题导致的？
  2. 能够自定义 Try identify UART0超时时间？
  3. 以前的OSDK就十分稳定，随便重启OSDK程序都不会初始化不过。请问这里是什么原因？

    Try identify UART0 connection failed

    1、此错误是PSDK尝试与飞机进行通信时没有通信上。

    2、PSDK 3.4版本设置的尝试15s，15s未通信上会报错退出。

    3、PSDK 3.x中新增了波特率自协商逻辑，M300上飞机上电后运行PSDK后，注意一下不要通过DJI Assistant2来修改波特率。或者按照原OSDK的使用方式，PSDK代码中指定的波特率与DJI Assistant2手动设置为一致。

    1. 关于波特率自适应， 代码里面写了 #define USER_BAUD_RATE "460800"， 制订了波特率，怎样做到自适应呢？

    2. PSDK尝试与飞机进行通信时没有通信上。 但是为什么OSDK版本每次尝试都能成功呢，没有进行硬件改动

    看了这里 

     

    2、新版本OSDK与无人机通信的波特率采用自适应，仅需通过上述宏定义：USER_BAUD_RATE指定波特率，无需再通过DJI Assistant2设置无人机波特率。

    原来自适应指的是 代码预定义啊
