KPA500 P command not working from RPI and node red, any ideas?

davedkv
I've been trying all day to get the KPA500 to "wake up" with a P command sent
from a raspberry PI zero W running node red without success. Every other
command works perfectly.  If I hook up a laptop to the KPA500 it wakes up
every time using the KPA utility of course, anyone know what the difference
is?

Hi Dave

What is the display saying when you’re trying to power it up?. I had NodeRed code running for it just fine never had an issue with it.

I found at times I managed to get it into the binary upload mode which would mess it up.

To add to my previous email, if you check with the Hams on the Node Red
Amateur group in groups.io, someone will have a KPA500 flow that already
works.

Lyn WØLEN
Are you sending a " P " or a " ^P " ?  Both work for me from a PC.  But that's not the case with some of the commands.
