Re: [Discuss-gnuradio] Playing with gr-bokehgui

[Kartik Patel]

Hello Marcus, 

During my testing, I think, I set the time.sleep function by try and error. I didn't check for different PC. I will update it after testing it on my too slow AWS may be. 

Also, this resize issue is because Bokeh stopped the support of resize feature. If you can, use Bokeh V0.12.6, and tornado v4.4. I have to Port the code to recent Bokeh version. 

Thanks for the extensive verifications. I will try to update the basic suggestions this weekend probably.

Hello Marcus,

Just for starters, make sure you have v3.7.12 of GNU Radio. In particular, your GR should contain the commit `3c989f9`. Also, make sure you select Bokeh GUI instead of QT GUI in Generate Options field in Options block. For Bokeh GUI we have a different `main()` function template that has necessary procedure to start the server and the stream.

Also, thank you very much for the suggestions about the vector plotter. In addition to the vector plotter, the Histogram plotter and BER curve are also in pipeline. I am too busy with several deadlines and projects. But I will try to incorporate the things as soon as possible (maybe in summer). Sorry for the loong promise! 

Let me know if you still have trouble working with the module.

Thanks.

Thanks for the very-prompt response.  I know that you're probably very busy.

I managed to get to the point of GRC generating the correct startup code, with the "Bokeh GUI".  My repo was up-to-date, it's just that I hadn't actually built it.  Too many distractions...

But when I got to start now, I get:

Traceback (most recent call last):

IOError: Cannot push session document because we failed to connect to the server (to start the server, try the 'bokeh serve' command)

I can get past this error by setting a longer "time.sleep()" in the generated "main" -- I guess it takes a bit for the server to come up to a state where it can accept connections.

But now:
