Is anyone around experienced with SDR, especially the HackRF?

I am trying to send OOK data at a certain frequency but it doesn't work. I am basically recording the wave, then using ooktools to decode the wave to binary and the hackrf_ook to send the binary. It doesn't work...

Using GNURadio for replay attacks works great, since I am not testing it on a rolling code device.

Has anyone managed to transmit binary (or hex) with the HackRF or any other SDR as a matter of fact? I cant use rfcat with the HackRF.
