/dev/ttyUSB0 Serial Port Not working
Platform Used: Rasp Pi 2 Model B v1.1
OS Release : Raspbian GNU/Linux 8.0 (jessie)
I have a Node-red instance running with two serial ports, one serial in node and one serial out node.
The ports are configured correctly to use /dev/ttyUSB0 and have the green "connected" indicator on.
I have an xbee connected to the USB Adaptor and the serial out node can send messages successfully to my remote xbee.
However I can't get my serial in node to receive messages, I can confirm the messages are being sent successfully, but they do not appear in the debug console of of node red.
I have read a large number of blogs and forums and have edited my /dev/cmdline.txt. to remove all references to /dev/ttyAMA0.
It currently reads ;
dwc_otg.lpm_enable=0 console=tty1, 9600 root=/dev/mmcblk0p7 rootfstype=ext4 rootwait
I have seen references to other files to edit like /etc/initab but I can't find these and think they are not relevant for my OS version.
I have tried to disable the getty service using this command -> sudo systemctl disable [email protected]
However this seemed to have no affect. I am at a loss as to what is actually required.
Can you please help ?
