Im lost the server will not pass this line:

config.devices.add(u'audio',name='RSHFiq', AudioDevice(rx_device='Built-in Input',sample_rate=48000,channel_mapping='IQ'))

or

config.devices.add(u'audio',name='RSHFiq', AudioDevice(rx_device='plughw:0,0',sample_rate=48000,channel_mapping='IQ'))

or

addCallback(lambda rig: config.devices.add('RSHFiq',rig, shinysdr.devices.AudioDevice('Built-in Input', sample_rate=48000, channel_mapping=IQ')))

I know that this works:

d = hamlib.connect_to_rig(config.reactor, options=['-m', '2519', '-r', '/dev/ttyUSB0', '-s', '38400'])

what's the proper call to attach a iq radio?

config.devices.add(u'audio',name='RSHFiq', AudioDevice(rx_device='Built-in Input',sample_rate=48000,channel_mapping='IQ'))

This should work — without frequency control since there's no rig device, of course.

addCallback(lambda rig: config.devices.add('RSHFiq',rig, shinysdr.devices.AudioDevice('Built-in Input', sample_rate=48000, channel_mapping=IQ')))

There are some typos here (no d. in d.addCallback and a missing quote in 'IQ'), and I don't know if it's what you were actually trying or whether you copied it into the issue imprecisely.

Let's start with the simpler case of audio only. Please make sure you share exactly the text of the config file (you can leave out your config.serve_web call for privacy) and the full output of ShinySDR when you try to use that config file.

It should add config.devices.add.plugin rigctl control for its VFO and IQ audio input!

Tip: When posting code sections on GitHub, place "```" (three backticks) at the beginning and the end, so that they're formatted properly and not as miscellanous headings. (I've edited your previous post to do that so it's readable.)

The error message isSyntaxError: EOL while scanning string literal (config.py, line 28). It tells you line 28. Looking at line 28, we see

addCallback(lambda rig: config.devices.add('RSHFiq',rig, shinysdr.devices.AudioDevice('Built-in Input', sample_rate=48000, channel_mapping=IQ')))

There is the syntax error it is referring to: you have channel_mapping=IQ' instead of channel_mapping='IQ'.

But with that fixed, there are still problems: addCallback is not a global function; you have to call it on the deferred returned from hamlib.connect_to_rig, like so:

d = hamlib.connect_to_rig(config.reactor, options=['-m', '2519', '-r', '/dev/ttyUSB0', '-s', '38400'])
d.addCallback(lambda rig: config.devices.add('RSHFiq',rig, shinysdr.devices.AudioDevice('Built-in Input', sample_rate=48000, channel_mapping='IQ')))

That looks like it should work, but I haven't got your hardware so of course I can't test it.

pardon the formatting errors!!!

When I isolated the device in the server. removing the RTL and hackRF, It fails. Looks to be mad "ERROR:shinysdr:ConfigException: No devices have been configured using config.devices.add(...)."

Oh, right, you also need to specify that there are things to wait for. End the config file with

config.wait_for(d)

By the way, you should not be running shinysdr as root with sudo. Network servers running as root are unnecessarily dangerous.

I haven't fixed the permissions for ttyUSB0 so im using root for testing.

its still producing errors, having trouble passing frames?

Whoops, the manual's config example is a little inconsistent with naming. Add

from shinysdr.devices import AudioDevice

at the top if it's not already present, then change the add line like this, changing shinysdr.devices.AudioDevice to just AudioDevice.

d.addCallback(lambda rig: config.devices.add('RSHFiq',rig, AudioDevice('Built-in Input', sample_rate=48000, channel_mapping='IQ')))

That was progress .... one must now define a proper audio device!!! it should be something like this "plughw:0,0"

You need config.wait_for(d), not config.wait_for(5). This specifies waiting for d to finish its work (including adding the audio device as specified in addCallback). It does not take a time delay.

It works... Then the Web interface freezes becoming unresponsive, and there are no demod plugins available. IDK? Something is crashing on the backend of the server!!!! The server even keeps running after ctlC.

kpreid commented Oct 20, 2020

Unfortunately a problem like that generally indicates some issue with the GNU Radio components being used, and I cannot suggest any simple troubleshooting steps for you.

When you say no demod plugins at all, where exactly are you reading that and what does it say? If in the log, show me the text. If in the UI, a screenshot.

It's expected that various plugins will be only available if additional software is installed (e.g. rtl_433), but if the basic modes like AM, FM, etc. are missing then something's gone wrong with the installation of ShinySDR itself.

I have all of the plugins I need!

I dont know how the backed was put together to handle an IQ audio. It broken according to what Im doing. Aside from the confusion about configuration. I will stick to running rtl SDR's and HackRF's for now.

Let just say that as soon as I select the audioIQ device and click on the spectrum display to add another receiver, the web interface freezes. I've captures the terminal after the crash... and linked to screen captures.

I went ahead and check out the direct audio device config. The waterfall is intermittent with a 2sec delay, and if you click anything the web UI becomes unresponsive.

#config.devices.add(u'rig', AudioDevice(rx_device='plughw:0,0', sample_rate=8000, channel_mapping=1, usable_bandwidth=(0, 8000)))

gr::log :ERROR: audio_alsa_source1 - [plughw:0,0]: Device or resource busy

Based on this log line, it looks like your audio devices don't cooperate with being reopened promptly. If you look at shinysdr/devices.py, around line 575 you should find:

    # implement IRXDriver
    def notify_reconnecting_or_restarting(self):
        # Under some conditions on Mac, gnuradio.audio.source may stop working when the flowgraph is modified. Therefore, recreate it, which causes a glitch but doesn't leave the device permanently nonfunctional.
        self.__init_source()

Replace self.__init_source() with pass and see if it works better. That will disable reopening the audio device whenever a change is made.

That fixes the waterfall. Adding a receiver still crashes the backend.

This line in the traceback indicates that the change I specified was not applied. Perhaps you removed the line under __init__ and not the one in notify_reconnecting_or_restarting? Or, actually, I see you have it in site-packages — if you edited the downloaded copy then you need to either rerun setup.py install or edit the copy that's in the site-packages directory.

(In any case, this problem indicates that I really ought to disable this by default on Linux, if not everywhere. But that won't happen today.)
