I'm a newbie using Node-RED and I'm having some issues when I try to send messages in HEX. This is the conversion table that I need:
I have a setup with 4 stepper motors and I'm connecting through bluetooth. My idea is to controll the motors with Node-RED. The first test that I made was using my cellphone and it worked with the following "setup".
What I need to do is to send this messages with Node-RED, but I'm having trouble converting it. What's the easiest way to do it? Using a msg.payload (buffer) as
"["254","254","254","254","254","254","254","254"]" that's my answer.
