Hello, I am extremely new to Node Red, so I apologize if this is a simple question, but I cannot seem to be able to connect my Arduino to the Serial In or Out nodes.
I am using the browser version of node red, and my Arduino is on COM1. However, when I enter COM1 in the serial node settings, I get the error: "serial port COM1 error: Error: Error: No such file or directory, cannot open COM1"
Here are my node settings:
I tried this but nothing changed, so I guess this is not the issue.
I didn't remember installing this, so I tried to run this command, but I got an error saying it doesn't recognize npm? I googled the error and found that I need to download NodeJS first, so I went ahead and tried and now the command works, but unfortunately It still doesn't recognize my port.
You mean to reinstall the serial port node, right? I did that after the previous step but still no luck
Last night, I tried to install and run Node Red locally from the command line after trying all of this, and the node is working there perfectly, but it is still not working if I launch it from the Ibm cloud site. I would really like to be able to use the cloud site as I am using many IBM services in my flows, and I also feel it is easier for my teammates to log into the website and see the same space I have instead of asking them to import the flows every time I make changes.
Yess, this was it, I think my brain didn't make the connection at all; since I saw that the microphone node could hear me, I thought the serial node would somehow work in the same way. I am so sorry for the confusion @Steve-Mcl I should have known better, thank you for trying to help though!
