Thanks for the reply, @JKSH.

I've been wondering, I'll remove the code of forever {}, what would be a way to constantly poll if there's data to process? Should I just use a timer every 1 second to keep poking the process method with a simple boolean that returns if process is already running?.

You're welcome. :) Yes, using a timer is a good way to poll.

How can i create my signal for text edit with python3 ?
With as many ways i tried, but I did not succeed .. :(

nections, the parameters must be of types that are known to Qt's meta-object system, because Qt needs to copy the arguments to store them in an event behind the scenes.
...
Call qRegisterMetaType() to register the data type before you establish the connectio

Wow, that really helps!

Thank you so much!

I will try it right now

#2 is wasteful way indeed!
but in low baud rates it will help, but in this case I don't think this is a low baud rate.

EDIT : I said for example 1ms, you really don't need it this fast, it depends on the frequency of getting bytes, for example for 20Hz you will have 20bytes every second which means you need a timer with at least 50ms refresh time and of course you read from serial port in asynchronous way then you can't 100% trust this way to read byte by byte, So as @JKSH said you better don't use this way if you don't have a specific reason.

OH yes. thread without run...
thank you.

@SGaist Thanks for the link! I'll check it!
