esp32 - tcp_server_blink example

[flbauer]

Hello,

Hooray, I observed that in the meantime tcp_server-Example is available.
Is it already operational? When connecting with browser Im getting a reboot:

`I (2071) NETWORK: SYSTEM_EVENT_STA_CONNECTED received.

I enabled TRACE to see more: a new connection appears in the netconn callback for which no event descriptor is registered:

The mentioned behaviour occurs with browser.
When I use nc 44404 it works nicely.
However when cancelling the nc command and issueing a new one a reboot occurs.
