Hello, The virtualized serial ttyMCC is waiting the caracter end of line to print a message. For example, with a simple sketch like this I can't see the message with cat /dev/ttyMCC in the terminal : void setup { Serial.begin(38400); } void loop { Serial.print(45); delay(1000); } But if I add Serial.print("\n"), I receive it. So I tried to change parameters of /dev/ttyMCC with stty command but I can't. I don't have error message but there is no change. If I try to change the baud speed, I get the error : unable to perform all requested operations. Why ttyMCC parameters can't be modified ? Anyone can help ? Thanks
You don't have to change the baudrate because it is virtual. Just use 115200. I suppose because it is virtual it is not behaving as a standard serial port. It is good that you found the eol issue. Now that you know it you also can program around it I think it is faster than wait for the Udoo team to fix it. They have higher priorities I suppose.
Ok, thanks for your answer. The default baudrate is 38400, this is not a lot but I will work with it.
I have read somewhere here on the forum that the real baudrate is much higher in real time because it is a virtual serial. Setting the baudrate should have no influence on the performance of /dev/ttyMCC
