OSDK设备是STM32F40x，硬件不连接M300的USB口，只连接串口，这样的连接方式对于OSDK4.1和PSDK300有无影响。我实际测试的结果是，1、在一台第一次使用OSDK功能的M300上，跑RTOS版的OSDK4.1程序，MSDK能发送数据到OSDK，OSDK发送不了数据到MSDK。2、psdk300不接OSDK的USB口跑不通程序。

    PSDK 3.0接OSDK接口开发OSDK功能时，若只使用串口通信，需要通过以下代码设置(PSDK 3.0 github 代码），可以参考链接相关说明： https://sdk-forum.dji.net/hc/zh-cn/articles/4408437830041-PSDK-3-0%E7%89%88%E6%9C%ACOSDK-OSDK-5-0-%E9%83%A8%E5%88%86%E7%9B%B8%E5%85%B3%E4%BB%8B%E7%BB%8D%E4%B8%8E%E6%8C%87%E5%BC%95 ![](https://djisdksupport.zendesk.com/attachments/token/ILcvfLHKM5avmb2PXgrpG6ROb/?name=inline100211761.png)​

    参考你发的教程，现在STM32F40x跑psdk300也能跑通了，实现我想要的OSDK和MSDK的双向数据传输，但是有个问题，为什么stm32接上OSDK的串口和USB口跑PSDK300不需要开启“启动API控制”和配置波特率，不接USB只接串口还需要开启“启动API控制”和配置波特率才可以用

    配置波特率是通过串口自适应的，与USB连接应该没有关系，我这边只连接串口，波特率与飞机不一致的情况下也会重设波特率。能否提供一下完整的终端打印log。

    好的，log信息稍后提供，就是说“启动API控制”那个不勾选也是可以的吗

    是的，不勾选应该也是可以的。

    这个是M300关闭“启动API控制”和配置与OSDK设备不同波特率的log

    好的，这个问题这边再进一步确认一下，您可以暂时先配置使用。

    这个问题这边测试了一下，勾选启动API控制与USB连接应该没有直接关系，您是否是在使用中来切换勾选或取消启动API控制？DJI Assistant2界面的控件还是有用的，如果在使用中勾选和取消勾选会更改飞机的设置。飞机上电启动时默认是勾选的，此时使用SDK无需先设置，如果使用过程中更改了设置，此时飞机启动API控制对应为设置的状态值。
