In hierarchical block source_impl, output 1 is not connected internally #6

Closed mr-suw closed 10 years ago

mr-suw commented 10 years ago

Hi,

I am using a rtlsdr stick and run shinysdr with the following source configuration:

'osmo': shinysdr.plugins.osmosdr.OsmoSDRSource('')

My browser is google chrome 33.0.1750.91 beta.

After I check the run checkbox in the web interface the following unhandled error is thrown:

I seem to recall seeing a problem like this when giving osmosdr.source a bad device string (source_impl is part of osmosdr), but since the string is empty that can't be the problem here.

Could you look at the output that occurs before you connect with a web browser and see if there's anything that might be a complaint from OsmoSDR about not being able to set up the device?

kpreid commented 10 years ago

Since the hierarchical block reporting the problem is a source_impl, absent other information I'm going to have to assume that this is a bug in OsmoSDR. Sorry. I'll leave this open in case other people are having the same problem and can diagnose it better.

kpreid commented 10 years ago

P.S. When pasting in text please make sure to indent it by four spaces; this will format it monospaced and ensure the content is not interpreted as markup. I've edited your existing posts. Also, you might want to change your rootCap since you revealed it in posting the config file.

mr-suw commented 10 years ago

I solved it by updating gr-osmosdr to latest trunk version. Thanks for your time and great web interface.

kpreid commented 10 years ago

OK, that would seem to settle it. Thanks for the update!
