Serial message structure

Bonjour

If someone can tell me what I'm missing to have the same format of the message that I want to send by an rf433 frame
the first is OK and the second is NOK
thanks in advance

Hi,

It looks like there is a CR/LF at the end of the first message that is missing from the second one.

You can add / control the contents of a STRING using the 'node-red-contrib-string' node.
This can be installed from the 'Manage Palette' option.

Cheers,

Paul
