Hi!
I have a HackRF. I'm testing it.
It works well receiving in GRC with osmocon source, but when trying to transmit with osmocon sink I receive an error
FATAL: Failed to open HackRF device (-5) HACKRF_ERROR_NOT_FOUND
It is like if it were a problem of permissions, but it is not, the HackRF is working great receiving.
I Have tried with two HackRF, one transmiting one receeiving, this it the block diagram
I have updated the firmware of both of them to the last one (2017-02)
this is the error output
Using Volk machine: sse4_a_64_orc

FATAL: Failed to open HackRF device (-5) HACKRF_ERROR_NOT_FOUND
Trying to fill up 1 missing channel(s) with null sink(s).
This is being done to prevent the application from crashing
due to gnuradio bug #528.
The first one is receiving (numer 1), the second (number 0) is the one wich fails
Using ubuntu 16.04 LTS.
Any clues?
regards
