Hi!
I was hoping to piggyback on this thread since I am having a similar problem with the clock sync and LTE connection. I am also working with a 1.1 Mayfly model with LTE Bee, hologram, and a Hydros 21 CTD sensor.
So far I have tried several locations with full LTE coverage through AT&T, reprogramming the Mayfly to make sure all changes Shannon mentioned here and in the instructional video were correct, and installing another LTE Bee module with no change.
Any help would be greatly appreciated.
Thank you!
