Hello,
I connected the netPi RTE 3 to a Raspberry Pi 3 B+ via LAN. I switched off DHCP and assigned a fixed IP address.
In order to send data to the netPI, I want to use UDP with Node-RED. I noticed, that Armin already posted the default UDP-Ports that the netPI listens to (see below), but I want the Port to be 9323. For this, I built up a Flow addressing the local IP of the netPI on Port 9323.
The "Listening"-Flow is running on the netPI and the "Sending"-Flow is running on the Raspberry Pi (See attachment).
The connection between them seems to be woking since I am able to Ping the netPi-IP-Address. But when I try to send messages to the mentioned Port 9323 nothing happens. Do I have to change some settings in the netPI's UI to allow listening to other Ports as well or is there another mistake I made?
Many thanks in advance,
André
