I have set of data which I have captured in the past using RTL-2832 usb devices and SDRSharp software under Windows. Now i would like to resend these data using the HackRF One and hackrf_resend command under linux. The function hackrf_transfer, both tx and rx under linux is working. However I would like to use this old captured data. I cannot record it again. That would be the easiest way. The data from SDR Sharp are 8 bit baseband IQ samples with wav extension. If I understand correct the data are in different format. SDRSharp saved it as 8 bit unsigned whereas hackrf_transfer is using 8 bit signed and without wav header. The switch '-w' is helping when we would like to reopen hackrf captured data in SDRSharp, but i need to do this in other way. From Sdrsharp to hackrf one. I have GNU Radio companion and trying to do some conversion. In this way SourceFile>>adding -127constant>>SinkFile. But something is missing. What kind of operation should I perform in GNURadio Companion between the source and sink file blocks?
