When to use this block?
Simple Network Time Protocol (SNTP) block can be used to get the time from any SNTP server.
Limitations
This block need to have a WIFI_block to communicate with the server.
Demo
Demo file : esp32_system_time_demo.slx
Inside of the if action subsystem.
Description
This demo use SNTP_block to update the ESP32 local time with the server. There it need to be connect to the WIFI first from the WIFI_block. Once it connect SNTP will synchronize the time with the server. Then System_time_block will get the internal time from the esp and give the output to a String_processing_block. It will process the string and print it for the user.
What should be happening?
Firstly it will connect to the server by using the WIFI block. When the WIFI connection is established it will update the local time. Please check the Serial Monitor for the more info (baud rate : 115200). It will log the current time there.
