automatic client reconnect #13

Closed IOTeule closed 2 years ago

IOTeule commented 2 years ago

Tried this client code for automatic reconnect, but fails. State isConnected() seems to be detected incorrectly.

while (1) {
if (client.isConnected()) {
std::cout << "Client connected successfully\n";
// send() } else { std::cout << "connect ... \n";
client.connectTo("127.0.0.1", 3000); } sleep(1); };

Would be glad to hear about your expert recommendation?

you're using the same "disconnected" client object after its socket have been closed. Once the socket is closed, it can't be reopened. In order to reconnect, just create a new client instance, and pass the same connection details to it.
