Whenever the RTC chip loses all power (including the backup battery) it will reset to an earlier date and report the time as 0:0:0 or similar. Whenever you set the time, this will kickstart the clock ticking. So, basically, the upshot here is that you should never ever remove the ba...
Reset time management By default, if a time is set it will not be reset after a reboot. Usingbegin(true)orbegin(true, HOUR_24)will reset the RTC registers. To know if a time has already been set use: bool isTimeSet(void) if(!rtc.isTimeSet()) {//Set the timertc.setHours(hours...
This post is about how to use the DS1307 Real Time Clock (RTC) module with the Arduino. You can also follow this guide for other similar modules.

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, theESP32needs to have an Internet connection and you don’t need additional hardware (like an RTC ...
If the RTC time is not consistent with the current time, because the data cannot be retained in the power-off state, if you need to keep the RTC time normal, you need to connect the RTC battery and update the RTC time Wireless scan Display the number o...
When "Auto select board/port is selected, manually switching the com port will select the corresponding board. note: the auto select feature relies on the vid/pid values returned by the usb driver which must correlate to the vid/pid of a board definition. Some manufacturers share vid/pid wit...

ESP will try to connect. If successful, it relinquishes control back to your app. If not, reconnect to AP and reconfigure. There are options to change this behavior or manually start the configportal and webportal independantly as well as run them in non blocking mode.How It LooksWishlistrem...
