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 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
