@ADR_PT you need to give the qt event loop time to pass the serial stuff to the OS and react to the signals QSerialPort emit accordingly

take a look here:

for a proper example

@ADR_PT you may want to start using QSerialPort the asynchronous (non-blocking) approach, by using signals & slots.
Take a look at the serial terminal example
