    What is the battery voltage that your Mayfly is recording in your data file?  We’ve had a few random failures of a mosfet on the board that will cause the Mayfly to read the incoming Lipo or USB voltage as being much lower than it really is (see this post: https://www.envirodiy.org/topic/innacurate-lipo-battery-voltage-data/).   Your logger code probably has a line in it that prohibits the bee from transmitting when the battery gets low, so it’s possible that your board has a bad mosfet which is tricking the Mayfly into not transmitting.
