We can also change the default pins also by re-defining them in the CMakeLists.txt
set(ARDUINO_SKETCH_DEFINITIONS "-DSERIAL2_TX=12" "-DSERIAL2_RX=13")
The name of all the availalable pins can be found in the pins_arduino.h file.
Before making any connectins, make sure that the jumper is set to 3.3V !
