LEAmDNS - Multicast DNS Responder (#5442)
* LEAmDNS Responder (II) Created a new branch to solve commit conflicts with recent changes to ESP8266mDNSResponder.cpp by d-a-v. * Removed millis() roll-over issues * fix LEA-mDNS * astyle on lea-mdns examples * add compatibility with lwIP-v1 * ditto * use strncasecmp instead of lwip's strnicmp from lwIP-v2 (thanks @devyte) * ditto * fixes * Update mDNS_Clock.ino unindent * Update mDNS_ServiceMonitor.ino unindent * Update LEAmDNS.h Add setInstanceName() forwarder for compat * Disable DEBUG_ESP_MDNS_RESPONDER by default * [Fixed] Debug output line DEBUG_OUTPUT needs to go inside DEBUG_EX_ function otherwise throw error if DEBUG_ESP_MDNS_RESPONDER is not defined

ESP8266 Multicast DNS (port of CC3000 Multicast DNS library)
|
||||
Version 1.1
|
||||
Copyright (c) 2013 Tony DiCola (tony@tonydicola.com)
|
||||
ESP8266 port (c) 2015 Ivan Grokhotkov (ivan@esp8266.com)

Extended MDNS-SD support 2016 Lars Englund (lars.englund@gmail.com)
|
||||
|
||||
This is a simple implementation of multicast DNS query support for an Arduino
|
||||
running on ESP8266 chip. Only support for resolving address queries is currently
|
||||
implemented.
|
||||
|
||||
Requirements:
|
||||
- ESP8266WiFi library
|
||||
|
||||
Usage:
|
||||
- Include the ESP8266 Multicast DNS library in the sketch.
|
||||
- Call the begin method in the sketch's setup and provide a domain name (without
|
||||
the '.local' suffix, i.e. just provide 'foo' to resolve 'foo.local'), and the
|
||||
Adafruit CC3000 class instance. Optionally provide a time to live (in seconds)
|
||||
for the DNS record--the default is 1 hour.
|
||||
- Call the update method in each iteration of the sketch's loop function.
