Won't receive COM messages

[Vortex070]

I have a custom Arduino script that will not display any messages at all in Unity using the plugin. It will display that the device is connected and, in docklight, I am receiving messages. I've wondered into the code and the inputQueue will appear as null (meaning no messages are being received).

the following is my Arduino Code:

//player 2 commented out for single wheel
int p1Pin = 0; //player 1 potentiometer
//int p2Pin = 1;//player 2 potentiometer
int p1Val = 0;
//int p2Val = 0;
void setup() {
Serial.begin(9600);
}
void loop() {
p1Val = analogRead(p1Pin);
//p2Val = analogRead(p2Pin);
Serial.print("P1 Raw Val: ");
Serial.println(p1Val);
p1Val = map(p1Val, 305, 853, 0, 100);
Serial.print("P1 Mapped Val: ");
Serial.println(p1Val);
/*Serial.print("P2 Raw Val: ");
Serial.println(p2Val);
p1Val = map(p2Val, 305, 853, 0, 100);
Serial.print("P2 Mapped Val: ");
Serial.println(p2Val); */
delay(5);
}

Hello,

Have you tried the sample Arduino code provided with Ardity? It's at the bottom of this page.
If that code works with your Arduino, then you can use it to debug your other code.

Regards.

Hi,
I have the same problem. I open the DemoScene_AutoPoll in Unity while your example Sketch is running on an Arduino Yùn. The Arduino serial monitor gets the heartbeat messages.
The console in Unity prints "Connection established" and nothing more. This is Unity Version 2019.4.0f1 on Mac OS. The API compatibility Level is set to .Net Standard 2.0. But the same behaviour occurs on .Net 4.x. Do you have any ideas, what this could be?

Hello, Yes, I modified the code in the game so I could parse the messages and pass the values to the actual game. There is a message listener that you need to setup (if you do it manually) and in the message received función, you can print out the messages that you are receiving. If you're trying to catch the messages, I recommend you use Docklight instead, it's more straightforward to use. If you run into any issues, please let me know.

I tried to get the example autopoll scene to run with the arduino test code since that already has a message listener. On Mac OS I get a connection message but none of the following messages. If I use the arduino serial monitor it works fine. Strangely enough if I use the same code on a windows machine, it works without problem. Will look into this further and update here when I find the time.

Thanks for the help

Just a quick update: I set Dtr and Rts to true manually for the port in the AttemptConnection Method of the AbstractSerialThread Class. A quick test shows that setting either of them works just as well.
@Vortex070 Docklight seems to be Windows only unfortunately

Hello,
Thanks for the information, I'll update the package to include configuration for both flags then.
Thanks!
