MDNS connection failed after router restarts.

[hitenlulla]

Hello, I found this small problem, When the ESP8266 is on and the router goes off, on reconnection with router the Homekit accessories become 'not responding'. And when I restart the ESP, the accessories are back online. ps, I have used MDNS.announce() for every 10 seconds and everything works properly except this edge case.

I found a temporary solution though, it looks like when the connection is found after being disconnected, the MDNS service starts but the connection to the client is not made, I removed the line 3169 in arduino_homekit_server.cpp which is a return statement, to make the function always start making connection to the client when the device gets reconnected.

// arduino_homekit_server.cpp : line 3164
if (homekit_mdns_started) {
        MDNS.close();
        MDNS.begin(name->value.string_value, staIP);
        INFO("MDNS restart: %s, IP: %s", name->value.string_value, staIP.toString().c_str());
        MDNS.announce();
        // return;                                                      **<- Remove this line**
}

But this leads to blocking of Loop when the internet in the router is lost and I cannot afford that. Hence this workaround was a big flop. Can anyone help me solve this problem?

I encountered this issue before. My solution is to comment out this line. // MDNS.close();

Is this solution stable? Have you tested it in the long run?

Sorry I don't have a global social media. Github would be fine for us.

Please refer to this repo. It is a framework build base upon esp8266. It includes some common used functionalities as you can see them in the top menu of the screenshot. https://github.com/ruleechen/home-esp8266
