I have some data arriving via RF to a Raspberry Pi 3b+ and can see the data arriving via minicom in the Pi using the command
sudo minicom -D /dev/ttyAMA0 -b9600
I'm trying to access that data by using a
serial in node (which is also on the same Pi) set to the same port and baud rate, but there is no output whatsoever from the node.
Any ideas pls?
Make sure minicomputer is stopped before you start Node-RED as only one app can grab the serial port at a time.
Then try splitting on a time of say 100mS rather than wait for a character
Anfd is the user you are running Node-RED as in the dialout group so it can access the port ?
Splitting on time works for me.
