Hi in communication networks, GPS is often us to sync network elements and to get accurate timing. with nRF9160 MFW 1.3, "GPS time based configurable IO-pin / pulse" is available; with 1pps pulse. To this regard: where is best documentation to read more about this functionality (how to set it up) for which use case this has been introduced? how can I use it in my application to sync all devices? example: if I want to make sure that all my devices have the same time and they are in sync, how can I use it? To have the same time on all devices, I guess they need to receive the Time of the Day at first (or from time to time) and then keep the sync using the 1pps pulse? or how? Thanks
