Client to server approach

[pberna67]

Dear Invzblio

Serial redirection is a very good approach because avoid the code change, however it should work as a "telnet server" program. The idea is that remotely a telnet client program should be able to connect to a virtual telnet server in which I will see the equivalent view of Arduino Serial Monitor. If nobody is connected to the server, than the Serial.printf / Serial.println should be ignored, so the program can run quickly.
This avoid the need to be connected as is happening in your case.

Hi Paolo,

Thanks for your comment.

Using an egress model is a design choice for the following reasons:

• It allows to monitor multiple devices from a single listening console
• It allows to monitor devices behind a firewall or other NATing devices
• You don't need to deal with DHCP locking of IP addresses from multiple devices in order to monitor them over time. Simply launching the console and restarting the device will resume connection

In the current release, the connection attempt is done only once so if the console is not listening, you have only minimal impact at launch. Using the RECONNECT option forces the esp32 to try reconnecting and might add unwanted delays but that's not the default behavior.

Hope this helps.
