And a new program to try to set it up in bypass to see if we can see what’s failing that way. I’ve also posted this on GitHub here: https://github.com/EnviroDIY/ModularSensors/blob/master/tools/LTExBee_FirstConnectionBypass/LTExBee_FirstConnectionBypass.ino

You should set your end of line back to newline instead of carriage return when running this or you might get a lot of extra blank lines in the printout.
