Hi, ? am ne in Qt. I was trying to send data from STM32f407vg to Qt. The data is produced by RTC module and gives time, date (for example, 2024-03-11T17:01:24+08:00Monday). However the data read by Qt is not full in text edit always. It is like a loop below and repeated always. ``` 2 2 2 20 20 20 202 202 202 2024 2024 2024 2024- 2024- 2024- 2024-0 2024-0 2024-0 2024-03 2024-03 2024-03 2024-03- 2024-03- 2024-03- 2024-03-1 2024-03-1 2024-03-1 2024-03-11 2024-03-11 2024-03-11 2024-03-11T 2024-03-11T 2024-03-11T 2024-03-11T1 2024-03-11T1 2024-03-11T1 2024-03-11T17 2024-03-11T17 2024-03-11T17 2024 ..read more
