I’d like to add a multimeter to node red via the serial port interface.
I’m using a USB/RS232 converter.
How can I know the serial port path (the /dev/ttyUSB0 doesn’t seem to work)?
Does the Edge MC box needs to have special privileges to access the serial port?
Thanks in advance,
It might be an issue:
on the configure drivers page, the generic-serial option is grayed out…
Do you know if serial port is supported on software version eMMC-os43.1-nanopi-r1-stable ?
Finally it worked: you have to restart the node-red option to be able to use /dev/ttyUSB0
Hey @Emmanuel ,
Great to hear you got it sorted out
Thanks for keeping this post updated with the solution!
