This program allows to use the HackRF in half duplex mode with dynamic RX/TX switching. Currently this is implemented using standard input/output.
While there is no data incoming on STDIN, the HackRF is in receive mode and writes samples to STDOUT. When data is seen on STDIN, the receive process is stopped and the incoming data is transmitted. When the incoming data stream stops or only values of constant value are read on STDIN, the HackRF is switched back to receive mode.
Copy src/config.h.template to src/config.h and adjust it to your needs.
Then use ./make.sh to build the program. The binary will be called
build/hackrf_trx.
