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 gr-osmosdr 0.1.4 (0.1.4) gnuradio 3.7.9 built-in source types: file osmosdr fcd rtl rtl_tcp uhd miri hackrf bladerf rfspace airspy redpitaya Using HackRF One with firmware 2017.02.1 gr-osmosdr 0.1.4 (0.1.4) gnuradio 3.7.9 built-in sink types: uhd hackrf bladerf redpitaya file Number of USB devices: 19 USB device 1d50:6089: 000000000000000071c469c82d291f43 skip USB device 1d50:6089: 000000000000000071c469c825671743 skip 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
