When you power-up the sodaq one with tracker code you only have 30 seconds to send a command, after every commend the timer will reset to 30 seconds. After the 30 seconds the tracker program will start.
If you open a Serial Monitor and don't see anything, just press enter. You will see the menu again and the timer is reset to 30 seconds.
The "SodaqOne-UniversalTracker" is for our first version of the SODAQ ONE.
The "SodaqOneTracker_v2"is the same software but modified to work on the SODAQ ONE V2
Choose the correct software version for your board.

To use LoRaWAN you have to use your own LoRa keys, if the program does not safe your keys check if the Serial Monitor is on "Both NL & CR" next to the baudrate select. See: http://support.sodaq.com/wp-content/uploads/2016/02/serialMonitor_CRLF.png
