Messages not showing

Hello,

I followed the pdf with steps to get incoming messages into Unity from the COM port with the 'MyMessageListener.cs' script.
Upon pressing play, the only message I get is "Device Connected" and no more messages. I checked if the device is sending data via a python script and yes it is constantly sending data.

I have 2 suspicions:

  1. The data being sent from the device is in the form of hex bytes (as shown in the image). Is that a problem? Also, they come as packets.
    packs

  2. Does it matter if the device is arduino or not?

I'm sorry I have no idea what dts and rts means. There is no such flag in the method you indicated (see image).

Could you write the lines of code that I need to add to the AttemptConnection method here?

Hello,

Sure, no problem. Please locate these 2 lines:

serialPort.WriteTimeout = writeTimeout;
serialPort.Open();

And in between them, enable DTR and RTS like this:

serialPort.WriteTimeout = writeTimeout;
serialPort.DtrEnable = true;
serialPort.RtsEnable = true;
serialPort.Open();

Let me know how it goes,
Daniel W.

Hello,

It looks like there is progress after enabling DTR and RTS. I was getting the messages 'Arrived: I????' repeatedly (happened only once, directly after I made changes to the code), but I don't have a screenshot of that, because I cleared the console. But after that whenever I press play again, there were no values coming, just the 'Device connected' message and when I disconnect and reconnect the device, the message in the image below appears.

Again, to double check, I checked if the values are actually being sent by the device via my python script, and yes they are being sent, but not to Unity apparently. :(

Any ideas?

Really appreciate your responses btw.

Thanks,
Brolin

I'm having the same problem...
Btw, I'm writing in arduino in C language, using Atmel Studio and flashing with AVR8.
Verified the port with arduino IDE monitor, and it indeed send the messages, but Unity just don't receive/show them.
Please if anyone find the solution I would be grateful!

Hello @samu158820 ,
In which scene are you experiencing the issue? and what is the delimiter of your data?

Notice that scenes like DemoScene_AutoPoll expect the data to be sent in lines, while the scene DemoScene_CustomDelimiter allows you to set a custom delimiter. So depending on the format of your data you need to use one or the other to test your device.

Regards.
