Per chance, are you looking for the quadrature demodulator?

Hello!
I am building a monitor where capture of I/Q samples to a file is triggered
on an pluggable detection scheme. For example, I want to capture say 10
seconds of I/Q samples when LTE is detected.
Is this an appropriate place to use

So, a block called db_logger is written in python and port is defined in
following way:
self.message_port_register_in(pmt.pmt_intern(in_port))
Well, I am not sure, this works fine in older version.

What does your message_port_register_in call look like?
Or is it a message_port_register_hier_in call? (should it be?)

Hi,
ok thanks. Does it matter how I everything is declared, but it is clear
that something changed since 3.6.5.1.
So i have hier block written in python where i define
in_port = 'in_port'
out_port='out_port'
These arguments are passed in the following way:
in_port is receiving port of a block tha
Hi,
not really, what it says is really "I can't find in ", with that list being the names of the registered ports.
So, the interesting thing is that seemingly,comparin
pmt::symbol("in_port") with pmt::symbol("in_port") doesn't quite work well.
I'd have to look into what pmt::comparator looks lik
Hi,
hm, could just tell me if I am thinking wrong, but this looks like some of
my blocks is also called in_port?

Hi Tom,
Yes, you will need one block for each RTL-SDR.
In Device Arguments you have to put: rtl=0 , rtl=1 , rtl=2 ...
You can also use the Osmocom Source block for this.

Hi Nemanja,
a blind suspicion: as "system" is a port that should be registered by
the runtime for each block, there might be some confusion happening.
Does it work better when you rename your block to something else?
Best regards,
Marcus

Hi all guys,
I recently installed 3.7.8, and before that I had 3.6.5.1.
I was using message passing in some of my blocks, but now I get error which
is following:
Could not find port: in_port in:

Hi
I am new to linux and GNU Radio, I am trying to create a frequency to voltage
converter, I tried looking into the source code of QT GUI Frequency Sink to get
an idea how it detects frequency. However, it seems a little complicated, is
there any particular function i should look out
