Data extracting question 2

Third party integrations Node-RED
1

Hello,

I am totally new to Node-RED.

I have a frame sent over UDP with the following format:

#+21/07/2023+01:03:13+25.19+27.31+25.90+0+0+20+0+0+0+0+11011111+%

I have start “#” and end “%”, as well as the separator “+”. I use it this way because in a VisualBasic APP of mine I use this beginning and end of the frame.

In Node-RED I manage to separate the data. What I don’t know is how to assign them to variables.

In the image there are a lot of tests, but you can see that the one used now is Split2.

How can I define variables, e.g. “Time” to the Array of the image (2: “23:39:51”) and so on for each of the fields?

Thanks

or you could just plug this in a function node and do something like


var payload ={
  "var1": msg.payload[0],
  "var2": msg.payload[1]
  ....
}
return msg;

Thank you very much.
Something so simple and I didn’t see it. It has helped me a lot.

Thank you
