 Testing:
 1. the bootstrap of MQTT
 1.a  use a bad password and bad user
 1.b  see if it stops trying after a MAX tries
 2. send the credentials over BLE
 2.a   use a bad password and bad user
 2.b  see if it stops trying after MAX tries
 3. have a bad WIFI (so it won't connect)
 3.a see if it stops trying after a bit
 4. has valid WIFI and MQTT
 4.1  see it connects
 5. Using BOOTSTRAP
 5.a see if it connects
 5.b turn off BOOTSTRAP - re-upload script
 5.c  see if it reads the EPROM correctly
