Learn how to request date and time from an NTP Server using the ESP32 with Arduino IDE. Getting date and time is useful in data logging projects to timestamp readings. To get time from an NTP Server, the ESP32 needs to have an Internet connection and you don’t need additional hardware...
In this tutorial we’ll show you how to get date and time using the ESP32 and Arduino IDE. Getting date and time is especially useful in data logging to timestamp your readings. If your ESP32 project has access to the Internet, you can get date and time using Network Time Protocol (N...
I'm using ESP32 board Lilygo T-Call with AXP192 PMIC and I'm trying to connect it to Internet using firmware based on ESP-IDF. I can get information from the modem but I can't connect to the network. I tried to change auth params, APN, username and password but no result. NET...
