The serial port does not work

[baghjanati]

The serial port does not send or receive information

I am not able to reproduce. Please send us a video or give more info.

I am encountering a similar problem.
The code I am executing is:

void setup() {
  Serial.begin(9600);
  digitalWrite(LED_BUILTIN, HIGH); 
}
void loop() {
    Serial.println("This is a test");
    Serial.write(98);
    delay(2000);
}

With the original IDE if I open this file/project, select Uno at COM6, upload, and open the serial monitor I will see "This is a test" and "b" printed.

However if I do the same steps with this ide, open the workspace/folder, select Uno and COM6, upload, and then open the serial monitor I will NOT see any output.

I am running v0.0.2 on Windows 10.

If it is worth anything I am seeing the same error as #107 in the "Arduino" output window, it seems to go away when this ide is run as administrator.

Thank you for the snippet, @stevenloppe

same error as #107

It comes from the Arduino language server and completely unrelated.

@stevenloppe, I started the PRO IDE form the HEAD of the source, and I can confirm, it works as expected:

I am going to try it with the 0.0.2 release on Windows right now.

Great, I could reproduce it. it is definitely a UI issue as I see in the messages in the logs.

[kittaakos]

I could reproduce it.

Steps to reproduce:

• Start of the application,
• verify and upload the sketch,
• open the serial monitor you can see the messages,
• stop the app,
• start the app, you cannot see the messages but they're received according to the logs.

I have found another bug which is related to the serial-monitor; if I start the app and attach a board that runs the serial-monitor sketch, then I cannot upload:

avrdude: ser_open(): can't open device "/dev/cu.usbmodem14401": Resource busy
Upload error: Error: uploading error: exit status 1

As I see, there are a few issues here; start the app, try to send anything to the connected board:

I received only two three timestamps, although it was enabled all the time.

I have completely rewritten the serial-monitor feature; the fix will be available with the next release.
