The next step is to set the SDI-12 address of the sensor. Communication with the sensor depends on its 1-character alphanumeric address (1-9, A-Z, a-z). Unfortunately, Decagon ships all of its sensors programmed to an SDI-12 address of 0, which cannot be used to get measurements from the sensor.
Within the SDI-12 library on GitHub, there is an example with instructions for changing the address. Find it here: https://github.com/EnviroDIY/Arduino-SDI-12/tree/master/examples/b_address_change
