Document how to use JSerialComm Transport Layer

[philippegirard]

I am using firmata4j on Windows 10 with OpenJDK 11 and I get the same errors as @centic9 #42 (comment)

I want to use JSerialCommTransport coded by @NorbertSandor here NorbertSandor@cd9cb59

However I am unable to import JSerialCommTransport with version 2.3.8.

Maybe a 2.3.9 version including the changes should be released? How can I use JSerialCommTransport in the meantime?

I think there should be a section in the readme that explain how to use each Transport Layer interface (and how to install optional dependencies when needed). I am not very good with maven.

I am happy to help and contribute if I can!

Until released, you can:

• add the com.fazecast:jSerialComm:2.6.2 dependency to your build
• copy the https://github.com/kurbatov/firmata4j/blob/master/src/main/java/org/firmata4j/transport/JSerialCommTransport.java file to your project
• use FirmataDevice(JSerialCommTransport(serialPortName)) to create the FirmataDevice instance

Let me know if the above steps are not sufficient.

I was able to make it work with the steps you specified. Thank you @NorbertSandor 🎉

I use the same workaround, but an official release with this new transport would be nice!

I made an unofficial release of firmata4j with the latest commit from the master branch. https://github.com/philippegirard/firmata4j-autopack

You can find today's release here: https://github.com/philippegirard/firmata4j-autopack/tree/main/releases/2021.04.28

If you don't need the jar-with-dependencies, you can pick and choose dependencies from here: https://github.com/philippegirard/firmata4j-autopack/tree/main/releases/2021.04.28/separated

Works very well on Windows 10 and gives access to the JSerialCommTransport transport layer

If you new more recent releases in the future, just open an issue and it will automatically compile the latest commit in an new release.
