Confused with QSerialPort control

[SOrton]

Hi,

I'm using this to receive data from an Arduino script:

QObject::connect(arduino, SIGNAL(readyRead()), this, SLOT(readSerial()));

This line is inside a "begin" button, and calls the readSerial function
It works perfectly when I first run the program and I receive data like this (as intended):
"x"
"x"
"x"
"r"
"x"
"x"

I then have a 'pause' button, where I send a stop command to my Arduino. Once I restart the Serial read (AFTER a pause), I'm receiving data incorrectly like this:
"x"
""
"x"
""
"x"
""
"r"
""
"x"
""
"x"
I believe this is causing an issue with my system.
I have a stop command in my Arduino to stop sending data, but do I have to somehow stop my signal/slot thing?
Would love if somebody can help me/ requires more info on my program.

Cheers

Make sure you are not doing your connect() statement a second time? Your output looks like you might be doing two serial reads for each readyRead() signal, hence the alternating "blank" results?

As a separate issue, do yourself a favour and change your connect()s to use the "new" syntax which was introduced over a decade ago....

@JonB That makes perfect sense! not sure how I missed that :)

Thanks for the speedy response!
