Hello stackprogrammer:
HackRF does not support 32ks/s, and Osmocom Sink does not resample the data for you (and sometimes does not give you a clear warning when something is wrong). So, I would check whether the stream is really being transmitted at 32ks/s (by using
something like Probe Rate).
Buffer also may affect the transmission time, but I don't expect too much changes in the number.

I created a file complex with a file sink in Gnuradio. It is a cos wave.
The size of a recorded file is 1,146,283,728 bytes. because data type is complex so recorded file has N samples...
N=1,146,283,728 bytes/(8 bytes)=143285466 samples....All of the samples in the recorded file are 143,285,466. So in another stage, I want to transmit it with Hackrf.......In the transmitter stage, I had a GRC file that you can see a screenshot of it.I set the sample rate to 32k.
According to the definition sample rate we expect to consume 32k samples every second.....So I want to predict that the second Hackrf should be transmitted and red led the show on...Second= 143,285,466/32000=44776.708125 second but in transmitting it only takes a long 80 seconds.My question is How I can compute the time of transmitting for a file that is set to no-repeat...For the Wav file and float type, I had the same problem...Thanks in advance
