I am developing a node-red flow using a raspberry pi's serial port com and baud rate, and I'm looking for a way to dynamically change the com port and baud rate from a message or a global variable.
I was unable to succeed despite trying a few options.
I'd be happy to check any solutions you know of
Hi @nadirm - pretty sure this is not possible (the serial node was not designed to be re-mapped at runtime)
You can however use env variables. Typically, you set an env var then node-red uses its value at startup.
