I'm a little perplexed. I have a weather station I've built. The code runs great on USB plug in. Even runs well when plugged into LIPO, but here's the thing: On USB the loop runs the way it's supposed to reconnect every 50 seconds. On LIPO, it runs once and never runs again (despite the fact that the board and all connected devices remain powered.)
The code is below. Any thoughts?
