In this tutorial, we will look at an interesting feature of the ESP32 development board through which we can acquire the epoch or Unix time from an NTP server. It provides a timestamp with a precision of approximately a few milliseconds of the Coordinated Universal time (UTC). This can be...
The latency timer is a setting that determines the amount of time that a USB device (in this case, the ESP32 FTDI adapter) waits before sending data to the computer. The default latency timer value is typically set to 16 milliseconds, which can result in a delay between when you input ...
It then takes the current time (in milliseconds) and checks if it's time to send the message. If the difference between the current time and the last time a message was sent is greater than or equal to the set transmission time interval TRANSMIT_RATE_MS , then update the last send time...
