Hi Victor, First of all : Thank you so mutch for making this program. this makes programming look easy:)) When i use the new uart-example nodes I get an error during Deployment. I dont know if I did somthing wrong, but here is wat I did: I copy/pasted the uart-example nodes into the main patch of a new project, and clicked ‘upload to Arduino’ (an Arduino uno), and got this error message: · Transpiling… · Project was successfully transpiled. Searching for device… · Port with connected Arduino was found. Installing toolchains… · Toolchain is installed. Uploading… Upload failed. ChildProcessError: Command failed: “C:\Users\Jeffrey\AppData\Local\Programs\XOD IDE\resources\arduino-builder\arduino-builder.exe” -hardware=“C:\Users\Jeffrey\AppData\Local\Programs\XOD IDE\resources\arduino-builder\hardware” -hardware=“C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\packages” -libraries=“C:\Users\Jeffrey\AppData\Local\Programs\XOD IDE\resources\arduino-libraries” -tools=“C:\Users\Jeffrey\AppData\Local\Programs\XOD IDE\resources\arduino-builder\tools” -tools=“C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\packages” -fqbn=“arduino:avr:uno” -build-path=“C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\upload-temp\build” “C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\upload-temp\xod-arduino-sketch.cpp” C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\upload-temp\xod-arduino-sketch.cpp: In function ‘void xod::xod\_\_uart\_\_uart::evaluate(xod::xod\_\_uart\_\_uart::Context)’: C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\upload-temp\xod-arduino-sketch.cpp:895:49: error: ‘SERIAL\_PORT\_HARDWARE\_OPEN’ was not declared in this scope state-\>uart = new (state-\>mem) HardwareUart(SERIAL\_PORT\_HARDWARE\_OPEN, (uint32\_t)getValue\(ctx)); ^ exit status 1 “C:\Users\Jeffrey\AppData\Local\Programs\XOD IDE\resources\arduino-builder\arduino-builder.exe” -hardware=“C:\Users\Jeffrey\AppData\Local\Programs\XOD IDE\resources\arduino-builder\hardware” -hardware=“C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\packages” -libraries=“C:\Users\Jeffrey\AppData\Local\Programs\XOD IDE\resources\arduino-libraries” -tools=“C:\Users\Jeffrey\AppData\Local\Programs\XOD IDE\resources\arduino-builder\tools” -tools=“C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\packages” -fqbn=“arduino:avr:uno” -build-path=“C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\upload-temp\build” “C:\Users\Jeffrey\AppData\Roaming\xod-client-electron\upload-temp\xod-arduino-sketch.cpp” (exited with error code 1) I tried replacing the uart input node with the other ones (uart-0, uart-1, uart-2, uart-3 and uart-usb) but i get the same result. I hope this is enough info Greetings, Jeffrey ---

Have you tried uploading a simple patch (like a single led node)? It looks like the toolchain upload may be failing. You need internet access the 1st time you upload a program to Arduino to get toolchain. Instructions for manually installing are included in a previous thread: [Can I manualy install the toolchain?](https://forum.xod.io/t/can-i-manualy-install-the-toolchain/319/2) ---

I uploaded a blink patch (a square wave node and a led node) and that worked ok. ---

Confirm, that’s a bug appearing on Uno, but not on Mega or Leonardo. See [#1370](https://github.com/xodio/xod/issues/1370). Will release a hotfix very soon. Meanwhile, as a hack, drill inside the `xod/uart/uart` C++ implementation and replace `SERIAL_PORT_HARDWARE_OPEN` with `SERIAL_PORT_HARDWARE` ---
