Hi!
I'm new to this and am trying to get my uno to communicate with a nano using the TX and RX serial pins.
My problem is with the IDE. I cannot set boards separately i.e. I cannot have one IDE window for a nano board and the other for an uno board. It just sets the same board for all windows which is frustrating.
Any thoughts?
I have already gone itno preferences and changes "false" to "true on the "export.applet.separate_jar_files" line.
You have to open 2 completely different instances of the IDE and set the board and port for each instance. By new instance, that does not mean to use the File, New command to open an IDE. It has to be a whole separate new instance.
OF course you can! Just start another instance of the IDE. I have done it many times while testing NRF24 communication between two Nanos on my laptop.

an I see! although could you elaborate how to open a new instance?
Open IDE, that would be the first instance.
Open IDE again, that would be the second instance.
Or you can double click the ino file for the Nano (the first instance) followed by the ino file for the Uno (the second instance).
In Windows you will get two separate icons in the taskbar; in other operating systems probably as well
And you can resize the windows so both can be on one screen.
You can also use this method to examine the source code for one program while writing a new program. OR comparing one version to another. You will love it after trying it for while.

Another solution is not to communicate using the IDE at all. IF you are just interested in Serial Monitor communication you can use programs like PuTTY under Windows, or screen under macOS or Linux. As a bonus, these are more pleasant to use than Serial Monitor.
Got it! Thank you! I just didn't understand the lingo
Now I know, it seems like a stupid and prohibitively unintuitive way of doing things. Because most people compare it to things like a word document where if you click new, it opens a completely independent document to the other. They could have a plus icon for another tab to open new programs withing the same instance. I probably don't know enough and there is a sound reason why; but it's still annoying that something so simple took so long haha
an interesting idea but it sounds out of reach for someone who's starting out like me! But thank you for the help, I'll make a note of it for the future.
