The tx_samples_from_file application is just an example application. You are free to modify it to meet your needs, including converting real-samples data to complex baseband data
The hardware, however, supports complex baseband data, In either sc16 or sc8 format “over the wire”. The host software (whether that’s the tx_samples_from_file example code or your own) is free to accept and convert files into the baseband format accepted by the radio hardware.
