why are you using a real time clock if you can get the time over the esp from a ntp Server?
<p>Good question but there are a few reasons: getting it from an RTC is in fact quicker. Also, when one uses the ESP as a client to get time from an ntp server, but at the same time want it to do something else as a host then that may cause some problems. I am sure it is possible but wouldnt directly know how</p>
Hi, If you're right, we agree<br>But I'm doing something like this application:<br>https://revspace.nl/EspWifiTracker<br>and I have no connection to any network for a long time<br>regards
