Hi, I'm new here and I have a problem with the Arduino node. When sending data from node-red to Arduino, the number -1 always arrives in Arduino, while sending data (of any type) from Arduino to node-red the node is always trying to connect and nothing happens. I tried to use the serial nodes that before downloading the Arduino nodes worked but make the connection but it doesn't works. What is the procedure? Thanks
Attualmente utilizzo node-red v.1.0.6 e node.js v.10.21.0
serial ports don't like being shared. You probably can't have both a serialport and arduino node both pointed at the same arduino port... (and also ensure that the arduino ide isn't running at the same time)
Yes i just tried. I tried with arduino node and only after deleted arduino node e tried with serial node. Arduino ide isn't running
