Read unknown buffer serial length

[Anonymous]

I need to readout all the char from the RX buffer after a CR has been sent. So send CR, wait for 1sec, dump the char. I can see how to do steps 1 and 3 but how do I set a 1 sec delay to wait for the buffer to fill up?

You can use sleep or a timer (depends on your script).

Sleep:

scriptThread.sleepFromScript(1000);//Sleep for 1s

Timer:

function timerSlot()
{
    timer.stop();

    //Do something.
}
var timer = scriptThread.createTimer();
timer.timeoutSignal.connect(timerSlot);
timer.start(1000);//Start the timer with a 1s interval

Hi Stefan,

Can you give me an example of using the single shot timer. I can't get it to work for love or money.

Thanks in advance.

Hi Stefan,

I must be missing something fundamental. I have two functions One starts a timeout timer(3 sec) every 10 seconds to send some data. The second function is called when some data is received. To process the data and stop the timeout timer. It would appear the stop timer command in the second function does not stop the time started in the first function. The timer is defined in the main body of the script.

What am I missing?
