Good morning Jeff,
yes "/data/" was a double, but I already understood the problem (there
was a discussion about that). The source signal block expects the
messages to be in dictionary format not pairs. Finally it works, thank
you for your help :)
Here is the final code:
from gnuradio impo
Is "data" a double? Thread() passes "args" to self.run() ...

Hi Jeff,
Thank you very much, all this time I didn't realize.
Now I have the following error:/Warning: failed to XInitThreads()//
//thread[thread-per-block[0]: ]: *pmt_car:
wrong_type : ampl",*/
there is something bad with the red marked line (below) , but according
to what is explained in t
Good evening,
I wonder where the function *msg_port_pub* is defined, I do not find it
anywhere.
I ask because the error "/can't interpret source code:
'messageGenerator' object has no attribute 'msg_port_pub'/**" persists.
I have implemented a handler that calls the function but it doesn't
Good morning Jeff,
I didn't write you yesterday because the code doesn't work yet as I want
and I was trying to understand why. I don't have any error message but
when I execute my flowgraph the value of the amplitude doesn't change
and I have the warning "failed to XInitThreads()".I have almo
Ha! No, not emailing myself, just a user who was replying directly. But to
continue my conversation (hopefully with the OP), here is some working
code. It does a print() because I didn't get around to actually sending a
pmt as a message, but you get the idea. Picture of flowgraph attached.

Sounds good. Only look at the C++ to figure out the general idea. I'd learn
Python threading first in a standalone program so you're not learning
(debugging) GR and python threading at the same time. Good luck - let us
know how it goes.
Also, please respond to the mailing list so everyone can bene
OK, it does work, as long as there is a message port defined and connected
in a flowgraph. I was trying too simple an example. You would do your
thread management in the start() and stop() functions.

It does not seem that python blocks can override start() and stop(),
which they should be able to do. So, don't go too far down that path. I do
not see anywhere in the code where this is used or would have been caught.
The embedded blocks are easier, be beware that GRC calls the init function

Minor correction - as is done in Message Strobe, you don't want the thread
to start running until start() is called. You can create the thread in
init() or start(). The Message Strobe creates its thread in start().

The work() functions are for stream handling. You may have already read
https://wiki.gnuradio.org/index.php/Message_Passing
The approach here should be to create a separate thread in your init, and
have that thread periodically public a message. There is a Message Strobe
block that does this (in
Good morning,
I want to generate a source controlled by voltage. Basically, I send
messages to a source in order to change its amplitude. I have built a
block to generate messages and pass them to the source. To do so, I
created an "embedded python block " that generates and transmits a
