Yesterday I've made test application in c# to try control 203 by ip protocol.
It works. I can receive oppo's broadcast and get information about server name, IP address and port. Comunication by TCP/IP was established and I've tested some commands like eject, close, off and on with server response about satus of execution.
I've met one problem: i can't make 203 ON when it is in standby state regardless that it should work (that is written in document about Control Protocol).
By the way the same situation is with original Oppo app for iOS.
Is there anybody who was sucessful with ON command?
