Hello,

I am using modul DFR1103 ("Gravity: GNSS Position & Timing Module") with RTC chip SD3031. 

I am able to configure/use 1sec pps output from gps module as interrupt, but I can't find how to enable RTC 1Hz SQW output to use it as 1sec interrupt for ESP32.

 

How can be 1Hz SQW output enabled on this module?

 

 

br,
