Rewritten for ESP32 by Hristo Gochkov (hristo@espressif.com)
|
|
|
|
This is a simple implementation of multicast DNS query support for an Arduino
|
|
running on ESP32 chip.
|
|
|
|
Usage:
|
|
- Include the ESP32 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.
