mDNS example

Shows how to use mDNS to advertise lookup services and hosts

Example workflow

  • mDNS is initialized with host name and instance name defined through make menuconfig and _http._tcp service is added to be advertised
  • WiFi STA is started and trying to connect to the access point defined through make menuconfig
  • The system event handler is used to pass the network events to mDNS so the service is aware when the interface comes up or down
  • GPIO0 (BOOT Button) is initialized as pulled-up input that can be monitored for button press
  • Example task is started to check if the button is pressed so it can execute the mDNS queries defined

Running the example

  • Run make menuconfig to configure the access point's SSID and Password and the default device mDNS host name and instance name
  • Run make flash monitor to build and upload the example to your board and connect to it's serial terminal
  • Wait for WiFi to connec to your access point
  • You can now ping the device at [hostname].local and browse for _http._tcp on the same network to find the advertised service
  • Pressing the BOOT button will start quring the local network for the predefined in check_button hosts and services

See the README.md file in the upper level 'examples' directory for more information about examples.
