你好,我们这边也遇到相同的问题,RK3399的安卓板,经常出现TypeC接口与遥控器连接有时可以,有时不可以,或者面在飞机飞着飞着就断了,之前的log

握爪子,我这边也是用RK3399做工业控制,连接在大多数是正常的,只是偶尔会抽风,总的发现一些规律:
1.首次安装应用和连接经常连不好,有时连不上,有时连上了Product,但是RemoteController组件加载不出来,有时没有图传。此时使用官方的Pilot连接使用一会,再切回APP就正常。
2.如果APP的so模块发生了闪退(libdjivideo.so (RTMPLiveStreaming::ffmpegShutdown()+76还是有小概率发生闪退),闪退后有一段时间可能连不上,怎么搞都不行。此时可以关闭APP等待几秒钟后再启动APP可能可以恢复。
3.APP运行久了,可能会有莫名其妙的连接不上,我是尝试每30分钟就重启一下adbd服务,然后APP运行满3天就重启一下APP。
4.工业板开机运行久了,可能会不听使唤,一直都连不上,或者连上了又断开然后又连上断开,不断循环。此时建议重启一下开发板。
5.如果板子故障导致温度超标(安装一些查询工具可以查看cpu温度),如果温度达到70度,大概率操作系统接近卡死,自然也连不上。
以上是血泪总结出来的经验,继续坑踩中...
