Errors when launching fcu.launch #80

Open TomW1495 opened 5 years ago

TomW1495 commented 5 years ago

Hi there,

I am using a Hummingbird and I am having trouble trying to launch the fcu.launch in asctec_hl_interface, I get the following error:

ERROR: could not open serial port /dev/pts/18 reason: open: No such file or directory

I have connected my laptop to the HL Serial 0 port via the adaptor, and have set the lfcu/serial_port to /dev/ttyUSB0.

/dev/pts/18 is created if I open a new terminal window, in this situation the node obviously fails to receive any acknowledgement packets and eventually times out.

Have I missed a step somewhere, and why is fcu.launch looking for /dev/pts/18 and not using /dev/ttyUSB0?

Thanks, Tom
