-- Setting up a UDP server is not possible.

 unless you use [AT firmware](https://www.espressif.com/en/support/download/at?keys=) version 1.7.0 or later. With older
 firmware, an application should be able to read fast enough to stay ahead of the network. This applies mostly to TCP
 protocol, where data would be lost without notification. On UDP using all firmware versions, the higher-layer protocol should recover from packet loss.
