it didnt work
how to test them ?
Code: Select all
/*
ESP8266 mDNS-SD responder and query sample
This is an example of announcing and finding services.
Instructions:
- Update WiFi SSID and password as necessary.
- Flash the sketch to two ESP8266 boards
- The last one powered on should now find the other.
