why serial data write on one line on console in terminal example is in package of 3 or 4 characters with qDebug?
-
hello, I want use serial data but when I write received data in file or qDebug with starting project example of Qt: terminal
m_console->putData(data); QString DataAsString =QString(data); qDebug()<<DataAsString;I get result:
":T"
"empe"
"ratu"
"re: "
"18.8"
"0:Hu"
"midi"
"ty: "
"59.0"
"0;\r"
"\n"but on console I have
:Temperature: 18.80:Humidity:59.00;thank you for your help

Hi,
How are you getting these data ?
What console are you referring to ? -
qDebug()adds an carriage return when it's done while the terminal example might just concatenate all the data received. -

:T05/05/19 23h55empe05/05/19 23h55ratu05/05/19 23h55re: 05/05/19 23h55:18.805/05/19 23h550:Hu05/05/19 23h55midi05/05/19 23h55ty:05/05/19 23h5559.005/05/19 23h550;
it's that like the data is not send in one time but by package...

Thats how serial lines work. As your data is line-based, you should use
canReadLine()andreadLine()fromQSerialPortRegards

@filipdns
It's up to you if you decide that marks your problem as Solved. However, switching to a faster speed can hardly address whatever your issue is, which is presumably a timing one. Beware that you do not find the problem arises again, as presumably it will if the data does not arrive fast enough even though you've upped the speed. As @aha_1980 said, I would have thought you need to correctly address when you read how much..... -
