/*
ESP8266 mDNS responder clock
This example demonstrates two features of the LEA clsLEAMDNSHost:
1. The host and service domain negotiation process that ensures
the uniqueness of the finally chosen host and service domain name.
2. The dynamic MDNS service TXT feature
A 'clock' service in announced via the MDNS responder and the current
time is set as a TXT item (eg. 'curtime=Mon Oct 15 19:54:35 2018').
The time value is updated every second!
The ESP is initially announced to clients as 'esp8266.local', if this host domain
is already used in the local network, another host domain is negotiated. Keep an
eye on the serial output to learn the final host domain for the clock service.
The service itself is is announced as 'host domain'._espclk._tcp.local.
As the service uses port 80, a very simple HTTP server is also installed to deliver
a small web page containing a greeting and the current time (not updated).
The web server code is taken nearly 1:1 from the 'mDNS_Web_Server.ino' example.
Point your browser to 'host domain'.local to see this web page.
Instructions:
- Update WiFi SSID and password as necessary.
- Flash the sketch to the ESP8266 board
- Install host software:
- For Linux, install Avahi (http://avahi.org/).
- For Windows, install Bonjour (http://www.apple.com/support/bonjour/).
- For Mac OSX and iOS support is built in through Bonjour already.
- Use a MDNS/Bonjour browser like 'Discovery' to find the clock service in your local
network and see the current time updates.

to need a small delay to get the job done. To allow for this delay, a 'delay' was added after one

processed (which might cause another send operation or change global states).
To avoid 're-entry-like' problems, UDP processing might be blocked for a short period of time.
