STM32F1 ubuntu24.04 arduino-ide(2.3.7) serial communication problem

[jfj]

Hi

I'm new to the STM32 board but not to Arduino IDE. I want to use two STM32 boards (with DXV lr30 900) for LoRa communication. I'm starting with a minimal program (without LoRa), just to see how the communication works between the STM32 and the Arduino IDE's serial interface. I can compile and download this program without any problems, but I don't see anything on the serial interface, whether using the ttyUSB0, ttyUSB1, or ttyS0 ports at 9600 baud.

here is the test program

void setup() {
Serial.begin(9600);
delay(2000);
Serial.print("hello");
}

void loop() {
Serial.print(".");
delay(1000);
}

Can anyone help me ?

Thanks in advance

Hello,

Arduino environment is not a ST product. Better to ask your question in Arduino forum: https://forum.arduino.cc/c/community

As @mƎALLEm said, this forum is not focussed on Arduino - so you'd be better asking in the Arduino forums.

For specific questions about the STM32 Arduino core, you could also try: https://www.stm32duino.com/

Whichever you choose, you will need to tell them what STM32 board you are using and  how, exactly, you have it connected to your Host computer.
