Hello, (raspberry pi 2b, node-red v0.19.5) I have a battery operated bluetooth thermometer (testing wine temperature) that I do not use very often... (or too often, I don't know). I switch it off when I do not need it to preserve the battery. But when I do I get the "serial port /dev/rfcomm0 cl…

For future reference if you select a node or nodes then use the Export feature then only the selected nodes will be exported.

Hi Colin, thanks for your comment. Here are only the selected nodes (I think) .... I though being able to connect the bluetooth to the tty needed to be included... Still : The question remains.... "How do you catch such an error in a flow so you can re-act on them ?" { "id": "dd0b9…

Or maybe the status node will catch it. (But basically you are saying it would be better if the error was only reported the first time?)

That is right. I set up the catch node to point to use only the serial node.

Assuming that is coming from the serial node itself rather than one of your debug nodes (you should be able to see the node name above the error) then I would have expected that to be caught by a Catch node. You say you didn't have much success with a Catch node, do you mean you got nothing from it?
