Serial Port nodes
#1
Hi all, is it possible to install Serial port nodes on openplotter's version (0.17.5) of node red?

if yes, how?

I can't join the "serial in" and "serial out" palettes

what are you trying to do?
i have used arduino. gpio and serial nodes all use serial connections..

sailoog has rebuilt the serial "usb" tab in next release.. it even has a enable/disable UART to free that one up."bluetooth"

hopefully it will be released soon.

you could pull data from web-socket send to serial.. example below, you can only have one WS so use the one already there or use link node, select your config for serial node "printer".i dont know anything about that printer but other ones use cups drivers ect for setup.this flow will continually send data you will need to setup a switch somehow to send once maybe a button on dashboard.
you could get all the data directly from the web socket "ws://localhost:3000/signalk/v1/stream" it might be more than you need or you could parse out what you want.as in example for lat.

Code:

it should have been already installed
type in a terminal
cd .node-red
npm install node-red-node-serialport
or
npm i node-red-node-serialport

sudo reboot

https://flows.nodered.org/node/node-red-node-serialport

or on nodered page http://10.10.10.1:1880 top right options button manage palette install tab search serial .. install
