Subject: | Re: [Discuss-gnuradio] HackRF + osmocon, RX works but TX doesnt |
Date: | Tue, 28 Feb 2017 12:21:25 +0530 |
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

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?

GDB has a 'break' feature; why doesn't it have 'fix' too?
