Fix for NTP blocking loop if connection is blocked

[croggero]

Fixes #615
NTP was blocking the loop causing 10seconds delays when executing when no NTP server could be reached. This fix will check every 10seconds and fall back to the device clock, updating it from the last NTP sync.

Thank you very much! This is very important mistake that I did. Thank you for fixing it :)

Just compiled the debug firmware, it's now kind of working.

Here a few issues I've encountered :

• scanning a admin card does trigger the wifi enable loop and the relay output will stay triggered until the wifi failed (~15 seconds)

• when starting the ESP-RFID board without any wifi available, it won't sync with the NTP server (obviously) but even if the wifi get available after, it doesn't sync with the NTP server ([DEBUG] NTP sync failed) and time will be stuck at the 1st January 1970

Thanks! I'll check these

hey @MaximeSharp I've just committed on dev a little fix for the NTP after wifi reconnect, can you please confirm that it's working?

Instead for the other one, can you please open a separate issue as I'm not sure it's related to this PR.

Thanks!

Compiled and tested, NTP sync after wifi reconnect is now working !

No problem, I will open a separate issue for the other one and add more info/logs.
