Hello All,
Hopefully this is the right place for this question...
I have a RPI set up with Venus os large installed. I want to be able to send some messages back and forth over serial to an Arduino Uno (mostly to tell the Arduino my water tank level for a side project). for my testing I have set the Arduino up to send a string over serial every 2.5secs however on the node-red debug I only receive some of the messages and most of them are very messy (see image). both baud rates are set up correct and to my knowledge the ports are set up right.
the string the uno is sending is "Data: " with a random number afterwards.
Thank you in advance.
Richard
