First post go easy on me. I am setting up my first basic flow in Node-RED on my raspberry pi.
I am using node-red-contrib-sox-utils , the sox-play and sox-record to play a message and then record a message. I have set it up successfully to overwrite the same file recording. However I would like to make the file name dynamic I can see the creator of this suggests I can use msg.filename to control this - but I am struggling to visualize / set this up.
When linking an inject into the node - I get the following debug messages.
I recommend watching this playlist: Node-RED Essentials. The videos are done by the developers of node-red. They're nice & short and to the point. You will understand a whole lot more in about 1 hour. A small investment for a lot of gain.
