Reply To: loggingInterval being ignored on v1.1 board. Logs every minute no matter what.

That’s one of the older, now-discontinued Xbee models.  Have you used that module before or is it completely new and unused?  We had many of them die after about a year of service.  Did you modify the SJ19 solder jumper on the back of the Mayfly to change the bee status pin from the usual Bee pin 12 to Bee pin 13.  I see you have it listed correctly in your sketch, but the jumper also has to be changed.   Have you tried running the sketch without the modem attached at all, to see if it sleeps and wakes appropriately (maybe set it to 5 minute interval instead of 15 so you don’t have to wait quite so long during testing).  It might also help to manually set the RTC first in case you haven’t successfully made a cell connection with that board yet to sync the clock.
