Balint Seeber balint256 at gmail.comDear Mad, Thank you very much for identifying this bug, adding a new device and sending the patch! I have added it all to the code on SVN, githib and the Windows plugin. As for the second issue, I can't shed any light on that. I'm actually still on 3.3 and 3.4 - I need to get with the 'program' :) Kind regards, Balint > -----Original Message----- > From: mad [mailto:mad at auth.se] > Sent: Saturday, 31 March 2012 10:44 AM > To: Balint Seeber > Cc: osmocom-sdr at lists.osmocom.org > Subject: Re: RTL2832 GNU Radio Source block now in gr-baz > > Hi Balint, hi list! > > Nice work creating a gnuradio source out of rtl-sdr, thank you for that. > But I've tested it using a Dexatek DVB-T Dongle which uses a FC0013 tuner > and there are two issues I ran into. > First, there is the wrong handling of a return value when setting the > frequency on the FC0013. > The attached patch integrates the Dexatek and fixes that issue. > > But the second one isn't as easy to fix because I guess you would need > some more insight into how a Gnuradio block is constructed to do that. > The following python std::runtime_error exception is thrown in grc > everytime a graph using the RTL2832 source is started. > > [...] > Wait delay: 11,130 ms > >>> gr_fir_fff: using SSE > Traceback (most recent call last): > File "/home/mad/gr/top_block.py", line 109, in <module> > tb = top_block() > File "/home/mad/gr/top_block.py", line 82, in __init__ > self.connect((self.rtl2832_source_0, 0), (self.blks2_wfm_rcv_0, 0)) > File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/top_block.py", > line 124, in connect > self._connect(points[i-1], points[i]) > File "/usr/local/lib/python2.7/dist-packages/gnuradio/gr/top_block.py", > line 129, in _connect > self._tb.primitive_connect(src_block.to_basic_block(), src_port, > AttributeError: 'baz_rtl_source_c_sptr' object has no attribute > 'to_basic_block' > > Perhaps you have some idea about that. > BTW, I'm using 3.5.2.1 Gnuradio with 2.7.2+ Python, your feaf6c commit of > gr-baz and using stand-alone rtl-sdr the stick works well. > > > Regards, > Mad
