Connection reset not detectable

[bkamenov]

I have a server on my Android phone using chrome.sockets.tcpServer API. When remote peer successfully connects, the communication is fine. However, when remote peer gets disconnected in a non clean way (no power, wi-fi lost) I cannot get any information that client socket has been reset. chrome.sockets.tcp.getInfo(clientSocket) says socket is still connected. chrome.sockets.tcp.send(clientSocket, data) returns resultCode=0. chrome.sockets.tcp.onReceiveError is not fired, except when I disable the personal hotspot as I use the program as a wifi server waiting for clients to connect. Sometimes, after a long time > 120 secs chrome.sockets.tcp.onReceiveError is called saying that clientSocket has been reset. I'm running Android 10.
Absolutely identical is the behavior on iOS - if the client loses power (unclean disconnect) I do not get any callback in the server code.
