Update via transmitter

To verify that time updates via a connected transmitter are working correctly, follow these steps:

1. Set a Test Time:
   Manually set the SmartSampler to a “wrong” time to ensure you can observe the update.
2. Adjust the Offset:
   • Navigate to Basic Settings and temporarily change the applied time offset.
   • Apply the new offset.
3. Synchronice the Time so the offest will be applied
4. Revert the Offset:
   • Restore the original time offset.
5. Power Cycle the Device:
   • Disconnect the main power (USB can remain connected).
   • Wait for at least 3 seconds.
   • Reconnect the power.
6. Verify the Update:
   • Use the Serial Monitor –> Cellular to observe the time sync. You should see messages like after it connected to the network:
     • 2025/05/08 02:56:12, update RTC
     • Set time to: 25/05/08,10:56:13+08 ignoring the offset from network
     • 2025/05/08 08:56:13, Time was off for more than 10 seconds, it has been set from cellular to: 2025/05/08 08:56:13
     • 2025/05/08 08:56:13, time was off for more than 10 minutes (this would restart the system if it is running already)
7. Handling Network Limitations:
   • If the transmitter cannot obtain the time from the network, you may see:
     • 2025/05/08 08:27:38, update RTC
     • Cellular time is not set, skipping setting time

Note: Not all network providers support automatic time updates. If this message appears consistently, it might indicate that the network lacks this feature.
