Hello!
I have a Photon, thats conected to my WLAN at home and the RTC-Clock is syncing. The display shows the right time - everything is perfect. A battery is connected to Vin for the RTC.
Now I want to disconect the clock from power, move it to a place without WLAN, repower it and want to see the time from the RTC. But my Photon does nothing, because it waits for a WLAN. Is there a way to check if WLAN is available and connect to it, or work offline when no WLAN is near?
Thanks for your help,
Robert
