Hi,

this looks like an issue with your upstart settings. My best guess is that your startup does not wait for all network interfaces to be ready. So that the driver does not find a connection to the sensor on boot-up. If its a systemd service, try to change the after target to something which indicates that the network is ready.

OK I get it , I will try so

Hi, I had the same problem as you. I tried the following step:

Enable UART serial port on boot

If the program reads data from sensor, chmod by custom udev rules by port or by group, or node and topic shows up but can't echo topics.

$ ll /dev/ttyS0 # this is what your sensor connected to
crw-rw-rw- 1 root dialout 4, 64 Jan  7 13:04 /dev/ttyS0 # the result should be 0666
