title: ESP32 Fails on set wifi Hostname
body: <p>I am using the AT command binary (provided by Espresif) to interface my wi-fi application. In order to identify the device over a network, I've changed the Hostname to a known name, but when I scan the network, the Hostname still being "Espressif", instead of being my "Own Hostname". </p>
  
  <p>Does anyone knows how to fix that? I actually think that it's an error on AT command's binary.</p>
