感谢这么晚还在回复。
重启后，就是回复了几个requests的消息。譬如：storage_config_get，config,airport_bind_status。然后就开始接收osd/state。因为只在测试通信是否正常，所以没有主动发起消息。
我的疑问是，即使上面几个requests的消息，回复的格式或内容有问题。会导致机场的异常吗。
另外，我看到requests主题的config方法有规律的每25秒收到一次，storage_config_get方法每5秒收到一次。
我检查我的回复，好像也是正常的，bid和tid是原请求的内容

尊敬的开发者， 您好，感谢您联系DJI 大疆创新。 未涉及到媒体上传storage_config_get可以先不用回，只关注上云时序即可。 config应该只需要在上云的时候请求一次，重复请求需要看下回复的消息是否正确。 相关文档地址：https://developer.dji.com/doc/cloud-api-tutorial/cn/feature-set/dock-feature-set/dock-access-to-cloud.html 希望我们的解决方案能够帮到您，感谢您的邮件，祝您生活愉快！ Best Regards, DJI 大疆创新SDK技术支持 -
config固定27秒收到一次，state就更恐怖了，一秒几十条到几百条。
