Re: [Discuss-gnuradio] HackRF + osmocon, RX works but TX doesnt

[Fernando Peral]

I have tried with the one in the repositories of ubuntu 16.04 (I think the package is called gr-osmosdr)  and with  the live DVD of pentoo, both fail the same way when using hackrf=0 both work using serial number.

Maybe there is some error with your osmocom source installation. I am using a HackRF one and it is working fine with osmocom sink block. Try re-installing the osmocom source.

The problem appears when using the hackrf for TX even if there is only one hackrf plugged.
Osmocon source makes the hackrf work with hackrf=0 or even leving the field in blank, but osmocon sink fails with the same parameters.
However  using the serial number works as much for one as for the other.

thanks for the help

try using the hackrf's serial number (d291f43, 5671743) rather than the index (0, 1)

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
