vortigont · vortigont · commit 12d90bd2662d · 2021-11-02T14:04:01.000+03:00
- increase default number of NTP servers up to 3 (match with Arduino esp8266) - activate SNTP over DHCP requests (match with Arduino esp8266) addressing issue espressif/arduino-esp32#4964 provided via espressif/esp-idf#7336
